Designated verifier signature scheme based on braid group
Shimin Wei · Journal of Computer Applications · 2008
The braid group is infinite non-commutative group,and it has many hard problems that can be utilized to design cryptographic primitives, such as the word problem, conjugacy problem and root problem. The designated verifier signature scheme was proposed using the root problem and conjugacy search problem in the braid group. Analysis shows that it is a simple, fast and efficient scheme with security features.
