Heterogeneous hybrid signcryption for multi-message and multi-receiver. [PDF]

open access: yesPLoS 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 ...

Malicious KGC attacks in certificateless cryptography

open access: yesProceedings 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.

On the Security of Certificateless Signature Schemes

open access: yesInternational 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.

A provably security and efficient certificateless short signature scheme [PDF]

open access: yesJisuanji 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

open access: yesAnais 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 ...

Cryptanalysis of Two Signature Schemes for IoT-Based Mobile Payments and Healthcare Wireless Medical Sensor Networks

open access: yesIEEE Access, 2020
Certificateless cryptography does not require any certificate for the public key authentication and users' public keys are transmitted with ciphertext/signatures or by making them available in the IoT-based public directory in a proper way.

Quantum attack-resistent certificateless multi-receiver signcryption scheme. [PDF]

open access: yesPLoS 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.

A certificateless Multi-receiver Encryption scheme based on SM2 signature algorithm

open access: yesHigh-Confidence Computing, 2023
The Multi-receiver Encryption (MRE) scheme can meet the secure data transmission requirements in multicast and broadcast scenarios. To meet compliance, critical information infrastructure in China should be protected with Chinese national commercial ...

Complex Conjugated certificateless-based signcryption with differential integrated factor for secured message communication in mobile network. [PDF]

open access: yesPLoS 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 ...

Efficient Certificateless Public Key Cryptography With Equality Test for Internet of Vehicles [PDF]

open access: yesIEEE Access, 2019
The fast progression of the Internet of Vehicles (IoV) has resulted in a large number of vehicles connecting to networks. This leads to massive growth in the data collected from vehicles via IoV. Fortunately, cloud computing provides a vast range of services such as operating systems, hardware, software, and resources.
