    Abstract: An apparatus and a method for performing an authenticated encryption with associated data (AEAD) operation of an encrypted instruction and a golden tag stored in a memory device in an event of a cache miss are provided. The apparatus includes a bus control circuit, a block buffer, a tag buffer and an AEAD circuit. The bus control circuit receives a read address from a cache for reading the encrypted instruction and the golden tag from the memory device. The block buffer receives and stores the encrypted instruction from the bus control circuit, wherein a size of the block buffer is preset to be N times a size of one cache line. The tag buffer receives and stores the golden tag from the bus control circuit. The AEAD circuit performs the AEAD operation upon the encrypted instruction and the golden tag to check whether the encrypted instruction is tampered or not.
