Certificateless signature and blind signature

Journal of Electronics (China), 2008
Certificateless 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).

Blinded-key signatures

Proceedings of the 2002 ACM symposium on Applied computing, 2002
We present a new cryptographic primitive, the blinded-key signature, which allows the inclusion of private keys in autonomous mobile agents. This novel approach can be applied to many well-known digital signature schemes, such as RSA and ElGammal.

On the security of blind signature and partially blind signature

2010 2nd International Conference on Education Technology and Computer, 2010
Blind signature allows a user to obtain a signature from an authority on any document, in such a way that the authority learns nothing about the message that is being signed. The blindness is an important property which distinguishes the blind signature from other signature schemes.

Security Arguments for Digital Signatures and Blind Signatures

Journal of Cryptology, 2000
This paper proves the security of a large class of signature schemes in the so-called random oracle model. This model assumes that the hash function used in a signature scheme behaves as a random function. However, it has been shown that there exist (contrived) schemes that are provably secure in the random oracle model, but not when used with a real ...

An Efficient ID Based Proxy Signature, Proxy Blind Signature and Proxy Partial Blind Signature

2008 International Conference on Information Technology, 2008
Identity-based (ID based) public key cryptosystem gives an efficient alternative for key management as compared to certificate based public key settings. A proxy signature is a method for an entity to delegate signing capabilities to other participants so that they can sign on behalf of the entity with in a given context.

Cryptoanalysis of Certificateless Partially Blind Signature and Proxy Blind Signature Scheme

2009 2nd International Congress on Image and Signal Processing, 2009
Blind signature and proxy signature are two im- portant crytographical primitives. Unforgeability is a primitive property of digital signature, it assures that any one cannot produce a forged signature on a message except the signer. However, blindness is an important property which distinguish with other signatures.

Certificateless Partially Blind Signatures

2009 First International Conference on Information Science and Engineering, 2009
Partially blind signature is a variant of blind signature. It allows a signer to explicitly include common information in a blind signature under some agreement with a receiver. It provides anonymity of users in applications such as electronic voting and electronic payment systems. While certificateless public key cryptography eliminates the key escrow

ID-Based Blind Signature and Proxy Blind Signature without Trusted PKG

2008
Private key escrow is an inherent disadvantage for ID-based cryptosystem, i.e., the PKG knows each signer’s private key and can forge the signature of any signer. Blind signature plays a central role in electronic cash system. Private key escrow is more severe in electronic cash system since money is directly involved.
