Claim 11:
12. The method according to claim 11, wherein: the receiving DMA module requests to obtain the cipher text data in the first address of the cache via the transport layer transmission module; the transport layer transmission module sends the request to the second loopback control module via the first loopback control module according to the source address of the DMA transmission; the transport layer reception module provides the request received by the second loopback control module to the memory access module; the memory access module obtains the cipher text data from the first address of the cache, and provides the plaintext data decrypted by using the first key to the transport layer transmission module; the transport layer transmission module sends the request to the second loopback control module via the first loopback control module according to the destination address of the DMA transmission; the transport layer reception module provides the plaintext data received by the second loopback control module to the receiving DMA module; and the receiving DMA module encrypts the plaintext data by using the second key to obtain the cipher text data, and stores the cipher text data to the second address of the cache.
