摘要
A method and system for generating ciphertext and message authentication codes utilizing shared hardware are disclosed. According to one embodiment, a method is provided of generating ciphertext message data and message authentication codes utilizing shared authenticated encryption unit hardware. In the described embodiment, plaintext message data is received at an authenticated encryption unit which comprises first and second authenticated encryption hardware modules. Thereafter, a first message authentication code (MAC) associated with a first authenticated encryption mode and a second MAC associated with a second authenticated encryption mode are generated. More specifically, the first MAC is generated utilizing the plaintext message data and first authenticated encryption hardware module and ciphertext message data and the second MAC are generated utilizing the plaintext message data and second authenticated encryption hardware module.
