  • Forward-Secure Signatures (FSS) prevent forgeries for past time periods when an attacker obtains full access to the signer’s storage by evolving the private key in a one-way fashion. To simplify the integration of these primitives into standard security architectures, Boyen et al. [2006] recently introduced the concept of forward-secure signatures with untrusted updates where private keys are additionally protected by a second factor (derived from a password). Key updates can be made on… CONTINUE READING
