Undeniable Signature Scheme: A Survey

Nowadays, almost all business organizations, committees use the internet to do transactions and confidential information exchange. So it is crucial to make these transactions secure and reliable. A system to be confident and trustworthy needs a function of cryptography, and also it must manage the keys of cryptography. The digital signature, which is universally verifiable, is a solution when there are disputes between the sender and receiver. Later the undeniable signature scheme was introduced as a modern technique to verify the validity of a message sent by the sender. The undeniable signature scheme has its properties to protect the interests of the sender and receiver. An authenticated verifier only can check the signature with the approval of the signer. In this paper, we have discussed various undeniable signature schemes-key generation, signature verification, and disavowal protocol. This paper compares different schemes of the undeniable signature on the various notations of security.
