Securing Electronic Transactions Using SHA-1 Secure Hash Algorithm

Abstract: This article discusses the requirements for portable electronic devices with cryptographic capabilities to perform very secure network authentication, fare collection, vending system regulation, etc. It also shows how the DS1963S or DS1961S iButtons® meet these requirements, such as secret protection, "Zero Knowledge Proof", and secure challenge-response through the secure hash algorithm (SHA-1).
