Study of Key Agreement Protocol Implementation in Constraint Environment

The key establishment (agreement) protocol constructed using public key cryptography (like RSA, D–H key exchange, Elliptic Curve Cryptography) can deliver more confidence in a lesser amount of bit for secrete keys, condense the obligatory communication bandwidth considerably, and reduce the process of computational of the client-side and requirements of storage space considerably for constraint environment. Real and valid implementation of key agreement protocol must have well-built network security and cryptography problem-solving procedure which also safeguards privacy (confidentiality) and integrity of the message. Secure and authentic execution of ECC-based key agreement protocol with Elliptic Curve Cryptography (ECC) offers substantial progress in cryptographic algorithm to defend data integrity, user anonymity, and secrecy of data than other public key encryption schemes (RSA, DSA) and also towards inspection, at a necessary situation of existing secure and authenticated procedure for key agreement protocol execution. Therefore, elliptic curve cryptosystem (ECC) provides proper accomplishment of authenticated and secured key agreement protocol for constraint environment with improved security than RSA. Hence, suggested conventions for the proposed protocol can execute on a wireless communication network to summarize the data confidence, performance parameter necessity, and efforts of calculation (cost of computation).
