Abstract
The invention provides a method for executing a cryptographic computation comprising a plurality of blocks while employing secret data in a processor, said executing being protected against spying out of secret data. To achieve a computational result of the computation, there is executed a multiple computation in which the computation is executed several times, at least twice. Within the multiple computation, blocks of the several, at least two, executions of the computation are executed in interlaced order.
