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.
Claims7
A verification process in a system comprising .alpha. communicating devices Ai to be connected to a central verification device B by the means of communication interfaces,
- each communicating device Ai
- having data processing means, communication means, memory means and random or pseudo-random generation means,
- performing a digital signature algorithm and producing a digital signature signal, and
- transmitting a digital signature signal to the central verification device B,
- the central verification device B
- having data processing means, communication means and memory means,
- verifying, in a batch, simultaneously a set of many digital signatures signals once all these digital signature signals have been received, by
- performing, firstly, processings of the received digital signature signals and by
- computing, secondly, on the processing results a verification calculation.
