Abstract
Test inputs are iteratively provided to a target asymmetric cryptographic system. Trace information resulting from operation of the cryptographic system is received corresponding to processing each test input. For each test input, test vector leakage assessment (TVLA) is performed on the trace information for the test input, t-values are stored, and the trace information is erased before proceeding to a next test input. In one example, a mean and variance of the trace information is updated for each test input.
