A Provably Secure Proxy Signature Scheme in Certificateless Cryptography [PDF]
Informatica, 2010 A proxy signature scheme enables an original signer to delegate its signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original signer. Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity-based cryptography, the notion of ...

Heterogeneous hybrid signcryption for multi-message and multi-receiver. [PDF]
PLoS ONE, 2017 To achieve secure communication in heterogeneous cryptography systems, we present a heterogeneous hybrid signcryption scheme. The proposed scheme allows a sender in an identity-based cryptography system to send multi-message to multi-receiver in a ...

A provably security and efficient certificateless short signature scheme [PDF]
Jisuanji gongcheng, 2019 In the certificateless cryptography system,there is no authentication relationship between the public key and the holder,which may cause a problem that a malicious user replaces the user’s public key.To This end,this paper improves the definition of ...

An efficient certificateless blind signature scheme without bilinear pairing
Anais da Academia Brasileira de Ciências, 2014 Recently, the certificateless public key cryptography (CLPKC) has been studied widely since it could solve both of the certificate management problem in traditional public key cryptography (TPKC) and the key escrow problem in the identity-based public ...

Quantum attack-resistent certificateless multi-receiver signcryption scheme. [PDF]
PLoS ONE, 2013 The existing certificateless signcryption schemes were designed mainly based on the traditional public key cryptography, in which the security relies on the hard problems, such as factor decomposition and discrete logarithm.

Complex Conjugated certificateless-based signcryption with differential integrated factor for secured message communication in mobile network. [PDF]
PLoS ONE, 2017 Certificateless-based signcryption overcomes inherent shortcomings in traditional Public Key Infrastructure (PKI) and Key Escrow problem. It imparts efficient methods to design PKIs with public verifiability and cipher text authenticity with minimum ...
