Method and apparatus for expansion key generation for block ciphers
摘要:
A key scheduler performs a key-expansion to generate round keys for AES encryption and decryption just-in-time for each AES round. The key scheduler pre-computes slow operations in a current clock cycle to reduce the critical delay path for computing the round key for a next AES round.
