Abstract
Disclosed herein are systems and methods for authenticated-encryption and authenticated-decryption operations for conducting authenticated-encryption communications between a host device and a peripheral device. A sending device performs authenticated-encryption operations that apply a symmetric encryption algorithm on plaintext to encrypt the data and generate an authentication tag or message authentication code ('MAC'). The sending device sends the ciphertext and a shared subset of the tag to the receiving device, and stores a non-shared subset of the tag in cache. The receiving device performs authenticated-decryption operations that verify the tag and decrypt the ciphertext to recover the data by applying the effective inverse of the symmetric encryption algorithm (or decryption algorithm) and using the known parameters.
