Security-Mediated Certificateless Cryptography [PDF]
, 2006 We introduce the notion of security-mediated certificateless (SMC) cryptography. This allows more lightweight versions of mediated cryptography while maintaining the ability for instantaneous revocation of keys. Moreover, our solutions avoid key escrow, which has been used in all previous mediated cryptography algorithms. We provide a model of security

Certificateless Public Key Cryptography [PDF]
, 2003 This paper introduces and makes concrete the concept of certificateless public key cryptography (CL-PKC), a model for the use of public key cryptography which avoids the inherent escrow of identity-based cryptography and yet which does not require certificates to guarantee the authenticity of public keys. The lack of certificates and the presence of an

IEEE Access, 2019 As the further extension of the multi-receiver signcryption, the multi-message and multi-receiver signcryption allows a sender to simultaneously signcrypt different messages for different receivers in only one logic operation, which makes it more ...

Revocable identity‐based matchmaking encryption in the standard model
IET Information Security, Volume 17, Issue 4, Page 567-581, July 2023., 2023 RIB‐ME provides the features of data confidentiality, sender authenticity and efficient revocation, where the security can be reduced to static assumptions in the standard model. Abstract Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access ...

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 ...

On the Security of Certificateless Signature Schemes
International Journal of Distributed Sensor Networks, 2013 Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

Malicious KGC attacks in certificateless cryptography
Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007 Identity-based cryptosystems have an inherent key escrow issue, that is, the Key Generation Center (KGC) always knows user secret key. If the KGC is malicious, it can always impersonate the user. Certificateless cryptography, introduced by Al-Riyami and Paterson in 2003, is intended to solve this problem.

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.
