摘要：In the era of electronic communications, almost all the business and personal transactions are being performed over the internet. Hence it is a necessity to make the transactions or exchange of information absolutely reliable and secure. A cryptographic system, to be complete and secure, requires a cryptographic function, a key parameter and a good management system to manage the cryptographic keys. However, no matter how secure an encryption scheme is, it is worthless if the other party is not convinced of the authenticity of the message/document. The undeniable signatures is a modern authentication technique that helps in proving the genuineness of the message or document. The undeniable schemes not only protect the interests of both the parties, but also secures the signer's ownership over the signature and message even further by requiring the participation of the signer in the verification process of the signature. In addition, it also provides the signer with the ability to deny the forged signature. This paper explores and draws comparison among various schemes on the basis of the security notions, along with performance in terms various operations required during the different phases of signature.
