Deniable Authentication Protocol using Promised Signcrypion Based on Hyper Elliptic Curve
Keywords:
Promised Signcrypion, Hyper Elliptic Curve (, ).Abstract
Anonymity and deniability has an essential role in promising internet environment. Promised signcrypion enable the sender to generate signcryptext with promised property sending it to the receiver. According to the promised property only the intended receiver can verify the original source generating the message. Hyper elliptic curve is considered suitable for constrained devices due to its lesser size key. In this paper we proposed an efficient promised signcrypion scheme based on the hardness of hyper elliptic curve discreet logarithm problem (HECDLP). We compare proposed scheme with existing scheme in term of cost (computational and communication). The proposed scheme reduces computational cost about 87.42% at sender side and 90.56% at receiver side and total communication overhead about 61.45 %. This scheme ensure the security issues like message confidentiality, message integrity, sender anonymity, authenticity.
