Authentication with RIPEMD-160 and Other Alternatives: A Hardware Design Perspective
Authentication with RIPEMD-160 and Other Alternatives: A Hardware Design Perspective
In this chapter two ways of providing authentication services (HMAC and CMAC) have been presented. Certain applications' criteria that have to be taken into consideration to choose between CMAC and HMAC were stated. Implementation details and system architecture were provided for both alternatives focusing on the manageability of these designs so as to be easy to incorporate any secure hash function in case of HMAC or any secure block cipher algorithm in case of CMAC. We focused on the design and implementation of RIPEMD-160 hash function that can be used for authentication in an HMAC mechanism and two techniques were presented that resulted to the optimization of the RIPEMD-160 hash function by 35% in throughput with a minor area penalty.
