Excerpt
Excerpt: Introduction And Preliminary Remarks: This RFC describes The Exponential Security System TESS [1]. TESS is a toolbox set system of different but cooperating cryptographic mechanisms and functions based on the primitive of discrete exponentiation. TESS is based on asymmetric cryptographical protocols and a structure of self-certified public keys. The most important mechanisms TESS is based on are the ElGamal signature [2, 3] and the KATHY protocols (KeY exchange with embedded AuTHentication), which were simultaneously discovered by Guenther [4] and Bauspiess and Knobloch [5, 6, 7].
