Abstract:
In most existing computer systems, data transmission and preservation in the form of plaintext are vulnerable to various attacks. In this paper, we use Parralelized memory Confidentiality and Integrity Protection technology (PCIP) algorithm to ensure the confidentiality and integrity of memory data. On the basis of PCIP, we use PCIP Bonsai Merkle Tree (PCIP+BMT) to protect the counter values of off-chip to reduce system delay and overhead. PCIP is that uses counter mode encryption to encrypt data while adding redundant data for integrity checking. Finally, we use the SimpleScalar Tool to simulate the PCIP and PE-ICE algorithms. The results show that PCIP is encrypted more effectively than the PC-ICE. Compared with the Hash algorithm, it can reduce the system delay and reduce the internal memory overhead. The tree mechanism adopted in this paper reduces the impact on system performance.
