Requires a 128 bit key
WebKeyExpansion – round keys are derived from the cipher key using the AES key schedule. AES requires a separate 128-bit round key block for each round plus one more. Initial round key addition: AddRoundKey – each byte of the state is combined with a byte of the round key using bitwise xor. 9, 11 or 13 rounds: WebJul 27, 2024 · Protecting keys with hardware security modules is one method of protecting data and includes both encryption (reversible) and hashing (irreversible). The following are some examples of standard algorithms and key lengths: AES – 128 bit or higher; TDES/TDEA – triple length keys; RSA – 2048 bits or higher; ECC – 224 bit or higher
