Abstract

This paper presents a message authentication code (MAC) with error-correcting capabilities which can be used for wireless transmission. Also the paper introduces a new nonlinear mixing function `Nmix ' which is cryptographically strong compared to other existing method and secured against linear, differential and other conventional cryptanalysis. This nonlinear function is used to compute proposed MAC from check symbols of Reed-Solomon (RS) code. Our MAC is shown to be secured even if a fixed pad is used in MAC generation.
