An Enhanced Simple Secure Remote Password Authentication Scheme Without Using Cryptography

Executive Summary

Since, the eavesdropping resistant remote password authentication schemes based on cryptography require that certain cryptosystems and/or cryptographic hash functions have to be implemented in the user's login device. Thus, many eavesdropping resistant remote password authentication schemes without using cryptography have been proposed. However, most existing eavesdropping resistant remote password authentication schemes without using cryptography are time-consuming, hard to learn, difficult to use, and/or difficult to implement. Recently, Yeh et al. have proposed a simple and efficient eavesdropping resistant remote password authentication scheme without using cryptography, ColorPallete.
