Unilateral authentication on low-cost devices

This paper deals with unilateral authentication on low-cost devices. Security properties for secure authentication protocol are specified herein. Based on these security properties we proposed four simple unilateral authentication protocols. Protocol for unilateral authentication using symmetric cipher, protocol for unilateral authentication using a HMAC function, protocol for unilateral authentication using a hash function and protocol for unilateral authentication using permutation. Their security against common attacks is discussed.
