Web2.1 RC6 Block Cipher Algorithm The block cipher algorithm RC6 appeared in 1997 [9] is an evolutionary improvement of RC5, designed to This algorithm depends mainly on the use of four working meet the requirements of the Advanced Encryption Stan- registers, each of size 32 bits. So, it handles 128 bits dard (AES). WebI can explain the special purpose hardware organization for the given algorithm. The RC6 encryption/decryption algorithm is a block cipher that operates on four w-bit input registers, A, B, C, and D. It uses a round-based structure, where each round performs a series of operations on the input registers using round keys. WebMar 26, 2024 · RC6 is one of the AES candidates.
