Abstract
In a method for protecting security-relevant data in a cache memory, a copy of this security-relevant data from a general memory is stored in the cache memory, and the method includes stipulating obfuscation parameters, determining a first cache set address from a memory address of the general memory at which the security-relevant data are stored, generating a first modified cache set address for a first cache set with a generation function using the obfuscation parameters and the first cache set address, and storing the copy of the security-relevant data using the first modified cache set address in a first cache line of the first cache set.
