Encryption is the process of converting plaintext into unintelligible ciphertext, whereas decryption is the reverse process to encryption that reveals the plaintext from the unintelligible ciphertext.

This paper proposes a high-throughput implementation of AES (Advanced Encryption Standard) supporting encryption and decryption with 128-bit cipher key.

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

Camellia, which also was selected for the original list, was reselected as the only Japanese encryption algorithm among 128-bit block ciphers. Significance of the adoption - Safety and performance An ...

In order to securely send data using a symmetric cipher, the sender and receiver use the same cryptographic key for encryption and decryption, respectively.

Block ciphers are a method of encrypting data in which fixed-length groups of bits are used, in combination with a symmetric encryption key, to encrypt and then decrypt data.

“When you encrypt lots of message blocks with the same key, at some point, you expect to have a collision with the inputs of the cipher and you can see a collision in the outputs of the cipher.
