A server in a public key system stores a list of fingerprints of digital data. Another fingerprint is computed for this list of fingerprints and provided to a client terminal. A client terminal in a public key system obtains a list of fingerprints of digital data from a first source in this system. The client terminal further obtains a fingerprint for that list of fingerprints from a first source as well as from a second source for comparing both obtained fingerprints. |
