摘要

Signcryption is a cryptographic primitive which at the same time give both the capacity of digital signature and public key encryption in a single logical step. Identity based cryptography is a distinct option for the traditional certificate based cryptosystem. Its principal thought is that every client utilises his identity information as his public key. Elliptic curve cryptosystem (ECC) have new received consistent attention because of their higher security per bit as compare to other cryptosystem. This paper presents a new identity based signcryption based on elliptic curve cryptography. Its security is dependent on elliptic curve discrete logarithm problem (ECDLP) and elliptic curve Diffie-Hellman problem (ECDHP). The proposed scheme can be very useful in low-end resource devices such as mobile communication, mobile banking, personal digital assistant (PDA) and internet of things (IoT).
