Security of transmitted information is a key element for any communication system it becomes more important as for as resource constrained and wireless/mobile networks are concerned, as security is an energy, memory and processing extensive application while securing resource constrained networks a care must be taken regarding usage of energy, memory and processing, as technology grows the need of securing data in resource constrained networks is getting more importance. Hyper elliptic curve cryptosystem can ensure confidentiality and authenticity by the use of digital signatures and encryption. HECC is the right choice for resource constrained networks, it provides high efficiency and shorter key size while providing same level of security as other public key cryptosystems provides. In this paper, we proposed two resource efficient Signcryption Schemes with forward secrecy based on Hyperelliptic Curve Cryptosystem The proposed schemes not only provide message confidentiality, authentication, integrity, unforgeability, and non-repudiation, but also forward secrecy.
