摘要：A method for protecting data against power analysis attacks includes at least afirst phase of executing a cryptographic operation for ciphering data in corresponding
enciphered data through a secret key. The method includes at least a second phase ofexecuting an additional cryptographic operation for ciphering additional data in
corresponding enciphered additional data. An execution of the first and second phases isundistinguishable by the data power analysis attacks. Secret parameters are randomlygenerated and processed by the at least one second phase. The secret parametersinclude an additional secret key ERK for ciphering the additional data in thecorresponding enciphered additional data.
