Digital Signature Scheme

We established a new approach for cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. We have embedded the features of ECC (elliptic curve cryptography) to the digital signature scheme based on Mandelbrot and Julia fractal sets. We offered a digital signature that has advantages of both the fractal based digital signature as well as of elliptic curve digital signature.Keywords: Fractal; ECC; Digital signature.© 2011 JSR Publications.

Digital Signature Scheme

Recently, Chen et al. proposed an efficient three-party encrypted key exchange protocol based upon Schnorr’s digital signature scheme with fewer rounds. However, J.H. Yang and C. C. Chang showed that Chen et al.’s protocol still has the high computation cost and communication cost. Moreover, Chen et al.’s protocol suffers from stolen-verifier attacks. Then J.H. Yang and C. C. Chang proposed a three-party authenticated key exchange protocol without password by using elliptic curve cryptography. Their improved protocol requires smaller transmitted message size and less communication times, which is well suitable for resource-limited environments such as mobile communication and mobile commerce. Unfortunately, we find that Yang et al.’s protocol is vulnerable to replay attacks, denial-of-Service attacks and impersonation attacks.

Digital signature is electronically password technique for electronic document signature. Elliptic curve cryptography is a method of public key cryptography based on elliptic curve mathematical. Digital signature scheme consists of three processes: initialization process, the signature generation process and signature verification process system. This paper analyzes the elliptic curve cryptosystems mathematical principle and technical performance. The paper proposes design of digital signature scheme based on elliptic curve cryptosystem.
