Tree Technology for Memory Confidentiality Integrity Protection

PCIP Tree is a Parallelized memory Condentiality and Integrity Protection technology (PCIP) method that pre-diffuses and encrypts the data stored in off-chip counter value for condentiality and integrity protection of data, adding redundant checking data to the protec- tion data block to ensure the integrity and condential- ity of the memory data. Then use the Simple Scalar tool to run 10 processors (SPEC2000) benchmark programs to simulation test. The result shows that the PCIP Tree method is greatly improved the running eciency and the efficiency of encryption methods to compare with the Parallelized Encryption and Integrity Checking En- gine (PE-ICE) method, at the same time, through the redundant data to check data integrity is better than using complex Hash algorithm to calculate the checking value and reduce system delay, reduce storage overhead chip, and ensure the real-time encryption and checking
