Abstract

In a method for voting using concatenated signatures, a plurality M of replicants for generating M redundant messages, where M≥2, and a plurality N of voter modules, where N≥2, are provided. Each voter module has a voter for voting the redundant messages and a crypto unit with a private key fragment for signing a message. The redundant messages of the replicants are transmitted to each voter module, so that the voter of each voter module generates a voted message on the basis of the redundant messages. N private key fragments are used to generate signatures for the voted messages that are checked by a public key of a reception unit. In the event of a successful check, the repeatedly voted message is accepted.
