METHODS AND IP CORES FOR REDUCING VULNERABILITY TO HARDWARE ATTACKS AND/OR IMPROVING PROCESSOR PERFORMANCE

In a general aspect, a GHASH semiconductor intellectual property (IP) core can include circuitry for calculating a GHASH function. The IP core can be configured to calculate the GHASH function by calculating the following quantities:X0=0;Xi+1=HkXi+∑j=0k−1∑n=0m−1Cki+jhijn, where for anyi andj; and∑n=...
