Abstract. Courtois, Finiasz and Sendrier proposed in 2001 a practical code-based signature scheme. We give a rigorous security analysis of a modified version of this scheme in the...
Recently non-abelian groups have attracted the attention of cryptographers for constructing public-key cryptographic protocols. In this paper we use the conjugacy problem in non-a...
In 2007, Kancharla et al. proposed an identity-based strong designated verifier signature (IBSDVS) scheme based on bilinear pairings, and claimed it unforgeable and non-delegatable...
Kabastianskii, Krouk and Smeets proposed in 1997 a digital signature scheme based on random error-correcting codes. In this paper we investigate the security and the efficiency of ...
Secure, anonymous and unobservable communication is becoming increasingly important due to the gradual erosion of privacy in many aspects of everyday life. This prompts the need f...
