ABSTRACT:
The process concerns a system, comprising communication devices A1, A2, . . . A.alpha. connected to a central verification device B by the means of communication interfaces wherein each device Ai, having data processing means, communication means, memory means and random or pseudo-random generation means, transmits to the device B, having data processing means, communication means and memory means, a set of DSS digital signatures. Once all the signatures has been received by device B, device B verifies them simultaneously by performing few calculations for verifying a great same number of signatures sequentially.
