A device and method for protecting data in which preset data (m) are stored in a first memory in a control unit; the data (m) are signed with a signature (σ_i) by a subscriber (i) belonging to a group of subscribers (1 . . . n) participating in a signature procedure; the signature is generated as a function of a first key (gsk_i) associated with the subscriber (i); the signature (σ_i) is stored in a second memory in the control unit; before the use of the data (m), a second key is used to verify whether the preset signature (σ_i) was generated by one of the subscribers (i) belonging to the group of subscribers (1 . . . n); and the signature (σ_i) contains an encrypted value, which characterizes the identity of the signing subscriber (i) and is to be decrypted by means of a third key.
