WebMar 1, 2024 · A block cipher is a cipher in which encryption is performed on a fixed-length block of characters from the plaintext. This cipher technique is widely used to implement encryption on bulk data. The usual block sizes are 64 bits, 128 bits, and 256 bits. For example, a 64-bit block cipher will take 64-bit plaintext as input and give out 64-bit ...

WebNov 11, 2024 · Block ciphers use the algorithm mode of Electronic Code Block and Cipher Code Block . These take text inputs and convert them into ciphertext by taking a block of text and generating a ciphertext of the same size. Block ciphers are relatively slower than stream ciphers, as a block of text needs to be covered, encrypted, and decrypted.

GCM is defined for block ciphers with a block size of 128 bits. Galois message authentication code (GMAC) is an authentication-only variant of the GCM which can form an incremental message authentication code. Both GCM and GMAC can accept initialization vectors of arbitrary length.
