Abstract
Facilitating communication using a digital signature includes: communicating software to a first party; receiving from the first party public keys of public-private key pairs generated using the software; and recording in a database the public keys in association with information pertaining to the software. The key pairs have the same private key. The software additionally provides digital signatures utilizing this private key. Each public key of these key pairs is generated, in part, based on data that is specified by the first party.
