Abstract
A method for deriving a partial signature for a subset of a set of messages. The method includes: receiving the set of messages and a signature of the set, which includes signature elements of the set; generating anonymized elements of the signature; generating a first verification element from messages other than those of the subset; generating a second verification element to prove the first verification element is well formed; and sending, to a verification entity, a partial signature specific to the subset. The partial signature includes a constant number of elements having at least the elements of the signature of the set of anonymized messages, the first verification element and the second verification element. The partial signature is verifiable with only the messages of the subset of messages. The second verification element is a function of derived values calculated from at least the other elements of the partial signature.
