摘要
The invention concerns a method for protecting an electronic cryptographic set with secret key against cryptanalytical attack, which consists in dividing a) the standard cryptographic computation process into several separate parallel processing stages using partial intermediate results distinct from those of standard computation; and b) reconstructing the final value from the separate intermediate partial results. The invention is useful for electronic sets such as incorporated systems.
