Abstract
Methods and apparatus for reducing the impact of latency associated with decrypting encrypted data are provided. Rather than wait until an entire packet of encrypted data is validated (e.g., by checking for data transfer errors), the encrypted data may be pipelined to a decryption engine as it is received, thus allowing decryption to begin prior to validation. In some cases, the decryption engine may be notified of data transfer errors detected during the validation process, in order to prevent reporting false security violations.
