Hybrid-Key Agreement Protocol based on Chebyshev polynomials ☆

This paper presented implementation of the Chebyshev permutation polynomials on hardware. The experimental results demonstrate that this is an efficient way to calculate the Chebyshev polynomials in a prime field. According to the hardware structure of the Chebyshev polynomial, a Hybrid-Key Agreement Protocol is proposed. The purpose of our protocol is to enable two end-users exchange a secret session key using both the key distribution center and the Chebyshev-based public key encryption. Advantage of public-key encryption is authentic and confidential for delivering secret keys, the addition of KDCs serves a widely distributed set of users. The proposed key agreement protocol offers satisfactory security and can be implemented hardware efficiently suitable for the low resource utilization.
