Abstract - Cloud has been around for two decades and it
consists of the vast amount of data from all over the world.
Most of the people at a personal level and organization level
have moved their data to the cloud and share data across all
around the world. The main challenge faced by everyone is to
share the data all over the world or at organizational level
securely without giving away the important data to any
exploiters. To overcome the challenge to share the data
securely over the cloud, an efficient data encryptionalgorithm
for encrypting data before sending it to the cloud. In this
proposed we are using a combination of Attribute-Based
Encryption and Byte Rotation Encryption Algorithm for
encrypting the data before sending it to the cloud. This will
help the user to securely store and share the data in encrypted
form.
Key Words: Cloud Computing, Data Privacy, Encryption,
Data Security, Data Sharing, Access Control.
1.INTRODUCTION
Cloud computing means storing data andaccessingthatdata
from the Internet instead of Using Traditional hardware for
most of the operations. More than 50%ofITcompanieshave
moved their Business to the cloud. Sharing of data over the
cloud is the new trend that is being set on. The amount of
data generated on a day to day life is increasing and to store
that all of the data in traditional hardware is not possible
because of limited storage capacity. Therefore, transferring
the data to the cloud is a necessity where the user can get
unlimited storage. Security of that data over is the next big
concern for most of us. After uploading the data to the cloud
use loses its control over that data. [1] Since personal data
files are sensitive, data owners are allowed to choose
whether to make their data files public or can onlybeshared
with specific data users. Therefore, privacy of the personal
sensitive data is a big concern for many data owners. When
any of the people upload the data onto the cloud they are
leaving their data in a place where monitoringoverthat data
is out of their control, the cloud service providercanalsospy
on the personal data of the users. When someone has to
share data over the data they have to share the password to
each and every user for accessing the encrypted data which
is cumbersome. Therefore, to solve thisproblemdata should
be encrypted before uploadingitontothecloudwhichcanbe
safe from everyone. Now the data encryption part brings
some new problems such as we have to provide an efficient
encryption algorithm such that if the data Is in encrypted
format it cannot be easily to get break or get accessed byany
exploiters. The next big concern is time consumption for
encryption. Traditional Hardware withbigconfiguration can
encrypt data in short amount of time but limited resource
devices suffers from this problem. They require more
amount of time of encryption and decryption. So,anefficient
crypto system is to be proposed which can worked equally
or heterogeneously on all of the devices.
2.RELATED WORK
Attribute-based encryption (ABE) is proposed by Sahai and
Waters. Attribute-based encryption (ABE) is a moderately
late approach that re-evaluates the idea of public key
cryptography.
Attribute-based encryption is also referred to as ABE is a
sort of public-key encryption wherein the secret key of a
person and the cipher-text is established upon attributes. In
an ABE, a person’s keys and cipher-texts are labeled with
units of descriptive attributes and a symmetric key can
decrypt a selected cipher-text only if there's a match
between the attributes of the cipher-text and the person’s
key. It reduces the quantity of key used and hence makes
encryption and decryption technique faster
3.PROPOSED SYSTEM
To address privacy issue in existing system we propose a
crypto-system for secure sharing of data over the cloud,
which uses combination Attribute Based Encryption and
Byte Rotation Encryption Algorithmforsecure encryption of
the data over cloud.
The main three works are as follows:
1. Identify the issues in cloud system for data storage
on cloud. Since data is not secure on cloud user can
upload the data in encrypted format.
2. Propose a crypto-system which can run on all
limited resources devices. It can take data from the
user and provide off-line-online service.](https://image.slidesharecdn.com/irjet-v4i10262-171201094107/85/Survey-on-Lightweight-Secured-Data-Sharing-Scheme-for-Cloud-Computing-1-320.jpg)

4.1 Proposed System Algorithm
Step-1: Start
Step-2: Accept the data from the user.
Step-3: The Attributes of the data fromtheusers’formats are
obtained by the Attribute-Based Encryption.
Step-4: With the help of these Attributes, Random Key is
generated, and type of data is obtained for encryption by
BRE algorithm.
Step-5: The data is converted into equal number of blocks
and N x N matrix will be generated on the basis of these
blocks.
Step-6: Based on no. of blocks, pool of threads will be
created.
Step-7: Run the threads in multi core system to create
encrypted data in short amount of time.
Step-8: A secret key is generated in order to open the
encrypted file which is stored in the cloud.
Step-9: The secret key is shared to the user via email or
mobile number of the authorised user. This key will be used
to decrypt the encrypted file.
Step-10: The file selected will be decrypted in the original
form using the key.
Step-11: Stop.

5. CONCLUSION
In this paper, the issue of sharing the data in cloud
computing securely is resolved. Data privacy can be
maintained by combination of ABE and BRE algorithm.
Authentication is used to guarantee data privacy and data
integrity. This indicates that the proposed system can be
used to enhance privacy preservation in cloud services.

Paper id 27201446
Paper id 27201446IJRAT This document discusses a proposed scheme called Blowfish Encryption (BE) to securely store data in public clouds using encryption. The BE scheme addresses weaknesses in an existing mCL-PKE scheme. In the BE scheme, users must register with the data owner before accessing data. The owner encrypts data using the Blowfish algorithm and secret key before storing it in the cloud. When a registered user requests data, the cloud verifies the user and retrieves the encrypted data without decrypting it. The user then decrypts the data using the secret key. The BE scheme improves security over mCL-PKE by requiring registration and keeping decryption with the user instead of the cloud. It also speeds up the process using the fast
IRJET- Securing Cloud Data Under Key Exposure
IRJET- Securing Cloud Data Under Key ExposureIRJET Journal This document proposes a new auditing mechanism to improve the efficiency and security of attribute-based encryption for securing cloud data. The existing single attribute authority model results in long wait times for users to obtain secret keys. The proposed approach employs multiple attribute authorities that can share the work of key distribution to reduce wait times. A central authority generates keys for verified users, while each attribute is managed by its own authority. The mechanism can also detect incorrectly verified users to enhance security. Analysis shows the auditing mechanism improves cloud security performance compared to previous single authority schemes.

Secure Data Sharing in Cloud through Limiting Trust in Third Party/Server
Secure Data Sharing in Cloud through Limiting Trust in Third Party/ServerIRJET Journal This document proposes a method for secure data sharing in clouds that limits trust in third party servers. It discusses shortcomings of existing approaches that rely fully on third parties for security operations like encryption and access control. The proposed method uses a two-layer encryption scheme, where the data owner performs lower layer encryption and the third party performs upper layer encryption. This limits the third party's access to the raw data. The owner also maintains control over access rights by directly providing keys for lower layer encryption to authorized users. The method is implemented and evaluated experimentally using Java and cloud services. It aims to address security and privacy concerns when outsourcing data storage while still offloading some operations to a third party.

It then encrypts the hierarchical files with the integrated access structure. This allows ciphertext components related to attributes to be shared among files, reducing both ciphertext storage costs and encryption time costs. The scheme is proven secure under standard cryptographic assumptions. If implemented, it could provide a more efficient encryption scheme

Stay Safe Women Security Android App Project Report.pdfKamal Acharya Women’s security is a critical issue in today’s world and it’s very much needed for every individual
to be acting over such an issue. This document describes a GPS based “Women Security System''
that provides the combination of GPS devices as well as provide alerts and messages with an
emergency button trigger whenever somebody is in trouble They might not have so much time, all
that they have to do is generate a distress emergency signal by shaking up their phone. Our system
provides a realizable, cost effective solution to problem detection. Nowdays due to recently
happened cases such as rape by drivers or colleagues, burglary etc., women security, especially
women security has become the foremost priority of the world. System uses the Global Positioning
System (GPS) technology to find out the location of women. The information of women's position
provided by the device can be viewed on Google maps using Internet or specialized software. The
companies are looking for-ward to the security problem and require a system that will efficiently
evaluate the problem of women security working in night shifts, traveling alone. We focus on the
proposed model that can be used to deal with the security issue of women using GPS based tracking
systems.

International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 04 Issue: 10 | Oct -2017 www.irjet.net p-ISSN: 2395-0072 © 2017, IRJET | Impact Factor value: 6.171 | ISO 9001:2008 Certified Journal | Page 1428 Survey on Lightweight Secured Data Sharing Scheme for cloud computing Shubham Chandugade1, Prachi More2, Shaikh Mohammad Shafi Rafiq3 1,2,3 Indira College of Engineering and Management, Dept. of Computer Engineering, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - Cloud has been around for two decades and it consists of the vast amount of data from all over the world. Most of the people at a personal level and organization level have moved their data to the cloud and share data across all around the world. The main challenge faced by everyone is to share the data all over the world or at organizational level securely without giving away the important data to any exploiters. To overcome the challenge to share the data securely over the cloud, an efficient data encryptionalgorithm for encrypting data before sending it to the cloud. In this proposed we are using a combination of Attribute-Based Encryption and Byte Rotation Encryption Algorithm for encrypting the data before sending it to the cloud. This will help the user to securely store and share the data in encrypted form. Key Words: Cloud Computing, Data Privacy, Encryption, Data Security, Data Sharing, Access Control. 1.INTRODUCTION Cloud computing means storing data andaccessingthatdata from the Internet instead of Using Traditional hardware for most of the operations. More than 50%ofITcompanieshave moved their Business to the cloud. Sharing of data over the cloud is the new trend that is being set on. The amount of data generated on a day to day life is increasing and to store that all of the data in traditional hardware is not possible because of limited storage capacity. Therefore, transferring the data to the cloud is a necessity where the user can get unlimited storage. Security of that data over is the next big concern for most of us. After uploading the data to the cloud use loses its control over that data. [1] Since personal data files are sensitive, data owners are allowed to choose whether to make their data files public or can onlybeshared with specific data users. Therefore, privacy of the personal sensitive data is a big concern for many data owners. When any of the people upload the data onto the cloud they are leaving their data in a place where monitoringoverthat data is out of their control, the cloud service providercanalsospy on the personal data of the users. When someone has to share data over the data they have to share the password to each and every user for accessing the encrypted data which is cumbersome. Therefore, to solve thisproblemdata should be encrypted before uploadingitontothecloudwhichcanbe safe from everyone. Now the data encryption part brings some new problems such as we have to provide an efficient encryption algorithm such that if the data Is in encrypted format it cannot be easily to get break or get accessed byany exploiters. The next big concern is time consumption for encryption. Traditional Hardware withbigconfiguration can encrypt data in short amount of time but limited resource devices suffers from this problem. They require more amount of time of encryption and decryption. So,anefficient crypto system is to be proposed which can worked equally or heterogeneously on all of the devices. 2.RELATED WORK Attribute-based encryption (ABE) is proposed by Sahai and Waters. Attribute-based encryption (ABE) is a moderately late approach that re-evaluates the idea of public key cryptography. Attribute-based encryption is also referred to as ABE is a sort of public-key encryption wherein the secret key of a person and the cipher-text is established upon attributes. In an ABE, a person’s keys and cipher-texts are labeled with units of descriptive attributes and a symmetric key can decrypt a selected cipher-text only if there's a match between the attributes of the cipher-text and the person’s key. It reduces the quantity of key used and hence makes encryption and decryption technique faster 3.PROPOSED SYSTEM To address privacy issue in existing system we propose a crypto-system for secure sharing of data over the cloud, which uses combination Attribute Based Encryption and Byte Rotation Encryption Algorithmforsecure encryption of the data over cloud. The main three works are as follows: 1. Identify the issues in cloud system for data storage on cloud. Since data is not secure on cloud user can upload the data in encrypted format. 2. Propose a crypto-system which can run on all limited resources devices. It can take data from the user and provide off-line-online service.

Apply Attribute Based Encryption Algorithm and Byte Rotation Algorithm for encryption of data to securely transfer the data between the users. 3.1ADVANTAGES Here data can be transferred from one user to another securely over the cloud. The system cost will be decreased. It will work on all limited resource devices. 3.2ARCHITECTURE AND MODULES DETAILS Figure 1: System model The architecture of the proposed system is shown in the figure which shows the users and the operations involved. The detailed description of the architecture is explained as follows: Nodes: The User is responsible for uploading and sharing its personal data on the cloud. On-line and Off-line Services: In On-line Service data will encrypted and directly transfer to the respective user. In Off-line Service if there is no Internet Connection the data will getencryptedfirst and then it will get stored in Main Server. Until the system does not comes on-line the data will not be shared over the cloud Cloud Service Provider: Cloud service provider is responsible for providing all the required services to its users according to their demands. Encryption and Decryption:Hereweareusingthe combination of ABE and BRE algorithm to encrypt and decrypt the files. File Upload and Download: The file which are uploaded on cloud are encrypted form. Users can download the file which are decrypted if he is authorized. 4. PROPOSED SYSTEM ENCRYPTION ALGORITHM Figure 2: Encryption Diagram In our proposed system data is encrypted before uploading to the cloud. Combination of Attribute BasedEncryptionand Byte Rotation Algorithm are used for the encryption of the data. ABE will help to identify the attributes of the data and BREA will perform matrix operations on the block of the data to be encrypted. Afterperforming encryptionoperation, a random key is generated alongside the encrypted data. Data will be send in encrypted format to respective user. To decrypt this data receiver has to enter the One Time Password (OTP) which will be matched with key generated using ABE algorithm. Figure 3: Decryption Diagram

Step-3: The Attributes of the data fromtheusers’formats are obtained by the Attribute-Based Encryption. Step-4: With the help of these Attributes, Random Key is generated, and type of data is obtained for encryption by BRE algorithm. Step-5: The data is converted into equal number of blocks and N x N matrix will be generated on the basis of these blocks. Step-6: Based on no. of blocks, pool of threads will be created. Step-7: Run the threads in multi core system to create encrypted data in short amount of time. Step-8: A secret key is generated in order to open the encrypted file which is stored in the cloud. Step-9: The secret key is shared to the user via email or mobile number of the authorised user. This key will be used to decrypt the encrypted file. Step-10: The file selected will be decrypted in the original form using the key. Step-11: Stop. Figure 4: Flow Diagram 4.2. IMPLEMENTATION This period of the venture is critical in light of the fact thatat this stage the hypothetical plan is changed over into functional one. This stage is a basic stage since this stage require exceptionally exact arranging and need the learning of existing framework and its detriments. The execution stage oughtto becreatedbyconsidering every one of the prerequisites, imperatives. The new framework ought to be successful and work appropriately. 5. CONCLUSION In this paper, the issue of sharing the data in cloud computing securely is resolved. Data privacy can be maintained by combination of ABE and BRE algorithm. Authentication is used to guarantee data privacy and data integrity. This indicates that the proposed system can be used to enhance privacy preservation in cloud services. 6.
