    摘要: The speed at which an AES decrypt operation may be performed in a general purpose processor is increased by providing a separate decrypt data path. The critical path delay of the aes decrypt path is reduced by combining multiply and inverse operations in the Inverse SubBytes transformation. A further decrease in critical path delay in the aes decrypt data path is provided by merging appropriate constants of the inverse mix-column transform into a map function.
