AES (Advanced Encryption Standard) is a symmetric block cipher algorithm that was adopted as a replacement for the DES (Data Encryption Standard) algorithm. AES is considered more secure than DES due to using a larger key size and being more computationally difficult to break. While AES is fast and reliable for encrypting files and documents, it is not suitable for encrypting communications due to the key exchange problem - for that, an asymmetric algorithm like RSA is typically used to securely exchange the AES key.

Advanced encryption standard (aes)
Advanced encryption standard (aes)farazvirk554 This document provides an overview of the Advanced Encryption Standard (AES). It discusses how AES was created through an encryption algorithm competition organized by the National Institute of Standards and Technology to replace the aging Triple DES standard. AES is a symmetric block cipher that encrypts 128-bit blocks using 128, 192, or 256-bit keys and 10, 12, or 14 rounds respectively. The AES encryption process takes the plaintext through several stages - substitution, shifting rows, mixing columns, and adding the round key - with the inverse being applied for decryption. Some potential security attacks on AES are also mentioned, such as related-key and XSL attacks, but it remains secure if implemented correctly.

Cryptography
CryptographyDarshini Parikh Cryptography is the practice and study of securing communication through techniques like encryption. It has evolved through manual, mechanical, and modern eras using computers. Cryptography aims to achieve goals like authentication, confidentiality, integrity, and non-repudiation. Common attacks include brute force, chosen plaintext, and differential power analysis. Symmetric cryptography uses a shared key while asymmetric uses public/private key pairs. Digital signatures and watermarks can authenticate documents. DRM and watermarks control digital content distribution.
AES Abstract
AES AbstractSathrukaSinha Advanced Encryption Standard (AES) is a symmetric block cipher algorithm used for securing information that was published by NIST as a replacement for DES. AES takes an input block and secret key to produce an encrypted output block of the same size. This work integrates both AES encryption and decryption using a 128-bit key length in VHDL or VERILOG, providing the input block and key for encryption and cipher block and same key for decryption to verify the proper output block is obtained through simulation results.

Simulations are included showing encryption and decryption using 3DES with equal and different keys.
Idea
IdeaOuissem eddine Amir BOUDOUR IDEA is a symmetric block cipher that operates on 64-bit blocks with a 128-bit key. It was designed in 1991 as an improvement over DES. IDEA consists of 8 rounds plus a half round. Each round splits the block into four 16-bit quarters, applies additions and multiplications using parts of the round key, exchanges inner quarters, and XORs with the output of the previous operations. The key schedule generates subkeys by rotating the main key and combining values. IDEA is considered secure and was faster than DES, though its simple key schedule was a potential weakness.

Presentation
Presentationrokham khawaja The RSA encryption algorithm is one of the most widely used public key encryption algorithms invented in 1977. It uses two large prime numbers to generate a public key and a private key. The public key is used to encrypt messages while the private key is used to decrypt them. RSA works by: 1) Generating two large prime numbers and computing n as their product, 2) Finding a number e that is coprime to another number m, 3) Finding d such that d*e is congruent to 1 modulo m, 4) Publishing e and n as the public key and keeping d and n as the private key.

Survey of Hybrid Encryption Algorithm for Mobile Communication
Survey of Hybrid Encryption Algorithm for Mobile Communicationijsrd.com This document proposes a hybrid encryption algorithm for securing data transmission in mobile communications. It combines DES and RSA encryption. DES is used for its higher encryption speed, while RSA is used to distribute keys safely. MD5 digital signatures are also used to guarantee data integrity and authentication. The algorithm encrypts data with DES, encrypts the DES key with RSA, and transmits both along with an MD5 signature to provide dual protection with DES and RSA encryption. This achieves security, confidentiality, integrity and non-repudiation for mobile data transmission.

CNS team 6.pptx
CNS team 6.pptxKannanN45 This document discusses the AES encryption algorithm and key generation. AES is a block cipher that operates on 128-bit blocks and is used widely to encrypt sensitive data. It was developed by NIST to replace DES after it was cracked. AES works by repeating rounds that perform substitution, shifting, mixing, and adding a round key. The number of rounds depends on the key size, being 10 for 128-bit keys, 12 for 192-bit keys, and 14 for 256-bit keys. A key schedule algorithm calculates the round keys from the initial key. The document also covers generating keys for symmetric and asymmetric encryption.

Shannon and 5 good criteria of a good cipher 
Shannon and 5 good criteria of a good cipher Sina Manavi The document discusses Claude Shannon and his 5 criteria for a good cipher. The criteria are that the amount of encryption should match the needed security level, the keys and encryption algorithm should be simple to implement and use, implementation should be as simple as possible without undermining security, errors shouldn't propagate, and the encrypted text shouldn't be longer than the original text. However, some of Shannon's concerns about complexity may no longer apply due to modern computers. The overall message is that ciphers should provide security without unnecessary complexity or expansion of the encrypted text.

In fact, Gopal was elected to the throne only to end Matsya Nyaya. Bhagalpur Abhiledh states that Dharmapala imposed only fair taxes on the people. Rampala abolished the unjust taxes imposed by Bhima. The Pala rulers were lovers of learning. Vikramshila University was established by Dharmapala. He opened 50 other learning centers. A famous Buddhist scholar named Haribhadra was to be present in his court. Devpala appointed another Buddhist scholar named Veerdeva as the vice president of Nalanda Vihar. Among other scholars of this period, Sandhyakar Nandi, Chakrapani Dutta and Vajradatta are especially famous. Sandhyakar Nandi wrote the famous poem of this period 'Ramcharit'.

Aes (advance encryption standard)
- 1. Directed by: Sina Manavi
- 2. What is AES? AES features: AES vs. DES AES vs. RSA Summary Q&A
- 3. After Des Cracked, Triple-DES which was slow they announced in competition for calling algorithms and between 15 algorithms on October 2000 Rijndeal which was invented by two Belgians, Joan Daemen, Vincent Rijmen. On 2002 Rijndael became AES. Rijndael is free in commercial and non-commercial use
- 4. designed simple Low memory cost High speed algorithm The key used to decrypt and encrypt is same Cipher text and plain text are same size Fast both in Software and Hardware
- 6. AES is a Symmetric block cipher algorithm ,a supersedes of DES. This cipher is good for encoding and decoding files, documents, and etc. Reliability and high performance made it distinct between other methods. On the other hand if you wish to use AES in communication, because of the Key exchange problem this problem is solved by using a asymmetric algorithm such as RSA. Message is encoded by a private key and the receiver decode it with the public key. Although asymmetric algorithms are slow, we can use them for exchanging the key and encode the data with symmetric algorithm,
- 7. DES is really old while AES is relatively new DES is breakable while AES is still unbreakable DES uses a much smaller key size compared to AES DES uses a smaller block size compared to AES DES uses a balanced Feistel structure while AES uses substitution-permutation
