In this paper, we present a novel symmetric-key block cipher, with variable block and key lengths, referred to as PATFC (pseudorandom affine transformation-based Feistel cipher), suitable for software and hardware implementations. PATFC adopts the 3-round Luby-Rackoff construction (a compact form of the Feistel network structure) for fusing pseudorandom(More)
This paper presents the simulation of privacy-related applications employing blind signature (BS) schemes. Two popular privacy-related applications: 'traditional BS based electronic voting system (EVS)' and 'traditional offline electronic payment protocol (EPP)' have been chosen here. A BS scheme is a cryptographic protocol that plays a(More)
