The invention relates to a method (200) for protecting security-relevant data in a cache memory, wherein a copy of this security-relevant data from a general memory is stored in the cache memory, having the method steps of: stipulating (210) obfuscation parameters, determining (220) a first cache set address from a memory address of the general memory at which the security-relevant data are stored, generating (230) 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 (240) the copy of the security-relevant data using the first modified cache set address in a first cache line (131) of the first cache set. |
