Summary :

In this paper, we propose a new digital signature scheme based on a third order linear feedback shift register for signing documents. This signature scheme is different from most of the signature schemes that are based on discrete logarithm problem, elliptic curves discrete logarithm problem, RSA or quadratic residues. An efficient algorithm for computing kth term of a sequence is also presented. The advantage of this scheme is that the computation is efficient than Schnorr scheme. We also show that the security of the proposed signature scheme is equivalent to that of Schnorr signature scheme.
