Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private informatio… WebIt simply guarantees that, if the symmetric encryption scheme is IND-CPA secure and the message authentication code is UF-CMA secure, the encrypt-then-MAC construction will be INT-CTXT and IND-CPA secure. ... The encryption process is non-deterministic and thus there are a practically infinite ciphertexts that could come from the same plaintext ...

Development of AES began in 1997 by NIST in response to the need for an alternative to the Data Encryption Standard (DES, discussed below) due to its vulnerability to brute-force attacks.

WebA symmetric key encryption scheme allows two parties that share a secret key to encrypt and decrypt messages. Such a scheme consists of 3 algorithms, one for generating the secret key that they will share, one for encrypting a message using that key, and one for decrypting a ciphertext, using the same key.
