Implementation of Efficient Hybrid Encryption Based on Elliptic Curve

Abstract

This paper implements an efficient hybrid encryption that combines symmetric key encryption, one time pad (OTP) and asymmetric key encryption, Elliptic Curve Cryptography (ECC). Elliptic Curve Key Establishment Protocol (ECKEP) is used to generate session key. Elliptic Curve Encryption Scheme (ECES) is used to encrypt and decrypt session key. One time pad algorithm has the key distribution problem, but it can operate at the high speed. Elliptic Curve Cryptography is used to encrypt OTP key for key security and to solve key distribution problem. This cryptographic primitive simultaneously performs the functions of both entity authentication and data encryption. This cryptographic primitive provides confidentiality, unforgeability, and non-repudiation for the delivered data simultaneously. It is intended for security intensive applications.
