We introduce the notion of sanitizable signatures that offer many attractive security features for certain current and emerging applications. A sanitizable signature allows authorized semi-trusted censors to modify – in a limited and controlled fashion – parts of a signed message without interacting with the original signer.

Certificateless signature and blind signature
Journal of Electronics (China), 2008Certificateless public key cryptography is a new paradigm introduced by Al-Riyami and Paterson. It eliminates the need of the certificates in traditional public key cryptosystems and the key escrow problem in IDentity-based Public Key Cryptography (ID-PKC).

Nominative Signature from Ring Signature
2007Since the introduction of nominative signature (NS) in 1996, there have been a handful of schemes proposed and almost all of them have been found flawed. The only one which is secure requires multiround of communications between the nominator and the nominee for signature generation. In this paper, we propose a novel construction which is efficient and

Signature Disguise or Signature Forgery?
Journal of the Forensic Science Society, 1986Abstract Signature identification and the questions of disguise, forgery and genuineness account for a significant proportion of a document examiner's case load. It is also one of the most demanding fields of document examination. To gather and evaluate a body of controlled data on the likely methods of producing disguised and forged signatures, 144 ...

A signature can be in any form or symbol, including manual form, a squiggle and in an electronic form to authenticate that the writing is that of the signatory. An electronic signature is no more than an electronic means of performing the functions of a signature ...
