Security-Mediated Certificateless Undeniable Signature Scheme

, 2018
Certificateless cryptosystems overcome the key escrow problem in identity-based cryptography. Mediated cryptography allows immediate revocation of public keys. Undeniable signatures limit the public verifiability of ordinary digital signatures.

Pairing-free certificateless blockchain-based access authentication method for spatial information network

Tongxin xuebao
Due to the single point failure and opaque certificate distribution process of the access authentication methods in a traditional terrestrial network, it was difficult to apply to a spatial information network with a highly complex and dynamic topology ...

Performance analysis of certificateless signature for IKE authentication

, 2011
Elliptic curve-based certificateless signature is slowly gaining attention due to its ability to retain the efficiency of identity-based signature to eliminate the need of certificate management while it does not suffer from inherent private key escrow ...

Security mediated certificateless signatures

, 2007
In PKC 2006, Chow, Boyd and Gonzalez Neito introduced the notion of security mediated certificateless (SMC) cryptography. SMC cryptography equips certificateless cryptography with instantaneous revocation.

An efficient certificateless signature scheme

, 2006
Certificateless public key cryptography (CLPKC) is a paradigm to solve the inherent key escrow problem suffered by identity-based cryptography (IBC). While certificateless signature is one of the most important security primitives in CLPKC, there are ...
