METHOD FOR PERFORMING MUTUALIZED CALCULATIONS OF MULTIPLE CRYPTOGRAPHIC OPERATIONS

Provided is a method for performing a plurality of cryptographic operations, that upon reception of a request to perform one of said cryptographic operations, prevents an execution by said processing system of said requested cryptographic operation until a predetermined waiting time (G) has elapsed, and before said predetermined waiting time has elapsed, receives one or more requests to perform another cryptographic operation, and after said predetermined waiting time (G) has elapsed, answers (S3) said requests by executing operations comprising mutualized calculations. The method determines said waiting time depending on execution times of said cryptographic operations to be performed and of said mutualized calculations.
