Download as PPTX, PDF2 likes443 views
This document proposes a system for secure cross-cloud single sign-on (SSO) using electronic IDs (eIDs). It discusses how most cloud services currently rely on weak username/password authentication and how eIDs can provide stronger authentication. The proposed system would extend an existing SSO architecture to allow a user to authenticate once using their national eID and then gain access to services from multiple cloud providers without re-authenticating. This provides stronger security while maintaining the convenience of single sign-on across different cloud service providers.

Claim based authentaication
Claim based authentaicationSean Xiong Claim based authentication provides a solution to common problems with user authentication across multiple websites. It allows an identity provider like Google or Facebook to authenticate a user and issue tokens containing claims like user details. Applications can then request specific claims from an identity provider through a selector. The identity provider signs the token and applications can verify the signature to trust the identity provider. This avoids the need for each application to implement its own authentication and allows users to reuse their login from an identity provider on multiple applications.

task scheduling in cloud datacentre using genetic algorithm
task scheduling in cloud datacentre using genetic algorithmSwathi Rampur Task scheduling and resource provisioning is the core and challenging issues in cloud environment. Processes running in the cloud environment will race for available resources in order to complete their tasks with the minimum execution time; it is clear that we need an efficient scheduling technique for mapping between processes running and available resources. In this research paper, we are presented a non-traditional optimization technique, which mimics the process of evolution and based on the mechanics of natural selection and natural genetics called Genetic algorithm (GA), which minimizes the execution time and in turn reduces computation cost. We had done comparison with Round Robin algorithm and used CloudSim toolkit for our tests, results shows that Meta heuristic GA gives better performance than other scheduling algorithm.

50120130406006IAEME Publication This document summarizes a research paper published in the International Journal of Computer Engineering and Technology. The paper proposes a model for data storage security in cloud computing using Kerberos authentication. Kerberos is an authentication protocol that allows nodes on a network to securely prove their identity to one another. The proposed model uses Kerberos to authenticate customers connecting to cloud servers. When a customer wants to store data in the cloud, they must first register with a third party. They are then issued a password and identity. The customer connects to Kerberos and gets a ticket-granting ticket, which they can use to obtain tickets to access specific cloud services. The model aims to address security issues with managing data in cloud computing environments by leveraging Kerberos
Kerberos Security in Distributed Systems
Kerberos Security in Distributed SystemsIRJET Journal Kerberos is a network authentication protocol that provides single sign-on capabilities for client-server applications by allowing nodes communicating over a non-secure network to prove their identity to one another in a secure manner. It uses tickets and secret session keys to authenticate users and services. When a client wants to access a service, Kerberos issues it a ticket-granting ticket which it can use to obtain service tickets from the ticket granting service. These tickets contain encrypted proofs of the client's identity that can be verified by the service. Kerberos supports cross-realm authentication and uses shared symmetric keys and timestamps to securely authenticate users within distributed systems. While effective, it has some limitations such as increased computation load, single point of failure if the
Efficient and Secure Single Sign on Mechanism for Distributed Network
Efficient and Secure Single Sign on Mechanism for Distributed NetworkIJERA Editor Distributed network act as core part to access the various services which are available in the network. But the security related to distributed network is main concern. In this paper single sign-on SSO mechanism is introduced which gives access to all services by allowing to sign on only once by users. In this mechanism once user logs in to the Trusted Authority Center TAC then application or services which are register to trusted center will automatically verifies the user’s credentials details and these credentials like password or digital signature will be only one for all applications or services. Unlike all other previous mechanisms where in, if user wants to have access multiple services then for every service distinct user credentials (username, password) must be required. SSO act as single authentication window to user for admittance multiple service providers in networks. Previously introduced technique based SSO technology proved to be secure over well-designed SSO system, but fails to provide security during communication. So here emphasis is given on authentication as open problem and on to refining the already proposed SSO process. And to do this along with RSA algorithm which was used in previous SSO process, we will be using MAC algorithm, which is intended to provide secured pathway for communication over distributed network.TAC i.e. Trusted Authority Center is used for sending token integrated with private and shared public key to user.

IRJET- Secure and Efficient File Sharing and Shared Ownership in Cloud Systems
IRJET- Secure and Efficient File Sharing and Shared Ownership in Cloud SystemsIRJET Journal This document proposes a system for secure and efficient file sharing and shared ownership in cloud systems. It introduces the concept of shared ownership where multiple users can jointly own a file. For a file access request to be granted, approval is required from a predefined threshold of the file's owners. The system uses AES-128 encryption to encrypt files for security. It allows owners to share files and ownership with other authorized users, who can then read from and write to the shared file. This provides more flexibility than systems with only single user file ownership.

25 7351 9003-1-ed secure cloud (edit a)
25 7351 9003-1-ed secure cloud (edit a)IAESIJEECS Key frame extraction is an essential technique in the computer vision field. The extracted key frames should brief the salient events with an excellent feasibility, great efficiency, and with a high-level of robustness. Thus, it is not an easy problem to solve because it is attributed to many visual features.
This paper intends to solve this problem by investigating the relationship between these features detection and the accuracy of key frames extraction techniques using TRIZ. An improved algorithm for key frame extraction was then proposed based on an accumulative optical flow with a self-adaptive threshold (AOF_ST) as recommended in TRIZ inventive principles. Several video shots including original and forgery videos with complex conditions are used to verify the experimental results. The comparison of our results with the-state-of-the-art algorithms results showed that the proposed extraction algorithm can accurately brief the videos and generated a meaningful compact count number of key frames. On top of that, our proposed algorithm achieves 124.4 and 31.4 for best and worst case in KTH dataset extracted key frames in terms of compression rate, while the-state-of-the-art algorithms achieved 8.90 in the best case.
25 7351 9003-1-ed secure cloud (edit a)
25 7351 9003-1-ed secure cloud (edit a)IAESIJEECS The adoption of cloud environment for various application uses has led to security and privacy concern of user’s data. To protect user data and privacy on such platform is an area of concern. Many cryptography strategy has been presented to provide secure sharing of resource on cloud platform. These methods tries to achieve a secure authentication strategy to realize feature such as self-blindable access tickets, group signatures, anonymous access tickets, minimal disclosure of tickets and revocation but each one varies in realization of these features. Each feature requires different cryptography mechanism for realization. Due to this it induces computation complexity which affects the deployment of these models in practical application. Most of these techniques are designed for a particular application environment and adopt public key cryptography which incurs high cost due to computation complexity. To address these issues this work present an secure and efficient privacy preserving of mining data on public cloud platform by adopting party and key based authentication strategy. The proposed SCPPDM (Secure Cloud Privacy Preserving Data Mining) is deployed on Microsoft azure cloud platform. Experiment is conducted to evaluate computation complexity. The outcome shows the proposed model achieves significant performance interm of computation overhead and cost.

IDaaS Defined
Identity (or identification) as a service (IDaaS)—Cloud-based approaches to managing user identities, including usernames, passwords, and access. Also sometimes referred to as “identity management as a service.
Identity and Access Management (IAM)
Identity and Access Management includes the components and policies necessary to control user identify and access privileges.
Authentication
Username/Password, digital signatures, digital certificates, biometrics
Authorization
Granular controls for mapping identities and rights

(Erl, 2014)
Single Sign-On (SSO)
Single sign-on (SSO)—PA process that allows a user to log into a central authority and then access other sites and services for which he or she has credentials.
Advantages of SSO
Fewer username and password combinations for users to remember and manage
Less password fatigue caused by the stress of managing multiple passwords
Less user time consumed by having to log in to individual systems
Fewer calls to help desks for forgotten passwords
A centralized location for IT staff to manage password compliance and reporting
Disadvantages of SSO
The primary disadvantage of SSO systems is the potential for a single source of failure. If the authentication server fails, users will not be able to log in to other servers.
Thus, having a cloud-based authentication server with system redundancy reduces the risk of system unavailability.
How Single Sign On Works
The single sign on mechanism enables one cloud service consumer to be authenticated by a security broker. Once established, the security context is persistent when the consumer accesses other cloud based IT resources.

(Erl, 2014)
Figure 10.9 - A cloud consumer provides the security broker with login credentials (1). The security broker response with an authentication token (message with small lock symbol) upon successful authentication, which contains cloud service consumer identify information (2) that is used to automatically authenticate the cloud service consumer across Cloud Services A, B, and C (3).

IRJET- Simultaneous ammunition for the multi-cloud computing simulation IRJET Journal This document discusses techniques for securing data in multi-cloud computing simulations. It proposes a protocol for securely transferring data between cloud servers and storage nodes using encryption and digital signatures. The protocol uses cryptographic algorithms like elliptic curve cryptography to encrypt data, generate digital signatures for authentication, and distribute encrypted data fragments across multiple clouds for redundancy and access control. A simulation of the protocol shows how cloudlets are distributed across different data centers and virtual machines using encrypted channels and access controls. The protocol aims to provide secure data transmission and storage in multi-cloud environments.

Presentation
PresentationLaxman Kumar Single Sign On (SSO) allows a user to authenticate once and gain access to multiple related systems without re-authenticating. SSO uses protocols like SAML and OAuth to issue authentication tokens after initial login. SAML is an XML-based standard that transfers user identity and attribute data between an identity provider and service provider using assertions. Metadata ensures secure transactions by allowing providers to look up authentication endpoints and validate digital signatures. The SSO workflow involves a user authenticating with an identity provider, which issues a token for the user to access a service provider. Major SSO providers include Microsoft, IBM, Red Hat, and ForgeRock.

ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITY
ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to
understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes
the answer to interpreting the decision-making process that AI malware analysis models use to determine
malicious benign samples to gain trust that in a production environment, the system is able to catch
malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI
as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in
many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to
conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to
balance explainability with security. Following this framework, designing a machine with an AI malware
detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its
decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on
choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique,
implementing AdvXAI defensive measures, and continually evaluating the model. This framework will
significantly contribute to automated malware detection and XAI efforts allowing for secure systems that
are resilient to adversarial attacks.

Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...
Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...Journal of Soft Computing in Civil Engineering In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling rejection in manufacturing processes of these end products. Springback phenomenon is the elastic strain recovery after removal of forming loads, causes geometrical inaccuracies in drawn tubes. Further, this leads to difficulty in achieving close dimensional tolerances. In the present work springback of EN 8 D tube material is studied for various cold drawing parameters. The process parameters in this work include die semi-angle, land width and drawing speed. The experimentation is done using Taguchi’s L36 orthogonal array, and then optimization is done in data analysis software Minitab 17. The results of ANOVA shows that 15 degrees die semi-angle,5 mm land width and 6 m/min drawing speed yields least springback. Furthermore, optimization algorithms named Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Genetic Algorithm (GA) are applied which shows that 15 degrees die semi-angle, 10 mm land width and 8 m/min drawing speed results in minimal springback with almost 10.5 % improvement. Finally, the results of experimentation are validated with Finite Element Analysis technique using ANSYS.

Secure cross cloud single sign-on (sso) using eid's
- 1. Secure Cross-Cloud Single Sign-On (SSO) using eIDs Presented by, Swathi Rampur (1cg11is092)
- 2. Agenda Abstract Introduction Related Work Existing System Proposed System Reference
- 3. Abstract Most cloud computing service providers secure their offered cloud services by username/password schemes, which have been proven to be weak. One of such mechanisms are electronic IDs (eID), which allow for unique qualified identification and strong authentication. Single sign-on defines the ability to authenticate just once in a distributed environment and gain access to several protected services.
- 4. Introduction Cloud computing is one of the fastest emerging IT topics today. Cloud computing into three different service levels: Most cloud service providers rely on username/password identification and authentication mechanisms. E-Government or e-HeaIth services usually have to fulfill higher security and privacy requirements. A lot of countries have already rolled-out national eID solutions to their citizens. (Eg:Aadhar in India)
- 5. Related Work Security Assertion Markup Language: ◦ Defines the most important standard for SSO. ◦ Designed for the secure exchange of identification, authentication, and authorization data. WS-Federation: ◦ An XML-based specification especially designed for enabling identity federation across different security realms. OpenlD: ◦ Users typically authenticate by username/password authentication mechanisms and receive a URL-based OpenlD identifier.
- 6. Oauth: ◦ OAuth provides an APT which enables applications the possibility to access specific user data of another application. ◦ Has also been adopted by some cloud SaaS providers such as Google or Salesforce.com.
- 8. In the above figure, it is assumed that a user want to access two SaaS applications of two different cloud service providers at the same time. User is registered to both cloud service providers , so that the user has to authenticate at the individual identity provider of each cloud service provider one after the another. The user has to authenticate First cloud service provider with the necessary details similarly for the Second cloud service provider and vice versa.
- 9. Proposed Architecture In the proposed system, combine both the secure authentication using eIDs and single sign. In the proposed system, combine both the secure authentication using eIDs and single sign.
- 11. Two service providers are taken for implementing SSO between different SaaS providers. The above figure shows that is supports the strong eID authentication at different SaaS cloud service providers by providing single sign on between those providers at the same time. So that by using a national eID a European citizens needs to authenticate at other cloud service providers protected STORK without re authentication. Two cloud service providers i.e. Google and salesforce.com use external interface for identification and authentication
- 12. Conclusion Username/password schemes are still the dominant authentication approach used for protecting SaaS applications. E-Government and E-Health services require higher security requirements .
