RSA Signature Scheme with Appendix - Probabilistic Signature Scheme is an asymmetric signature scheme with appendix combining the RSA algorithm with the PSS encoding method. The inventors of the PSS encoding method are Mihir Bellare and Phillip Rogaway. During efforts to adopt RSASSA-PSS into the P1363a standards effort, certain adaptations to the original version of RSA-PSS were made by Bellare and Rogaway and also by Burt Kaliski (the editor of IEEE P1363a) to facilitate implementation and integration into existing protocols.
