Digital Signcryption [PDF]

, 2005
Signcryption is a new cryptographic primitive which simultaneously provides both confidentiality and authenticity. Previously, these two goals had been considered separately, with encryption schemes providing confidentiality and signature schemes ...

A mutual and anonymous heterogeneous signcryption scheme between PKI and IBC

Dianxin kexue, 2020
Anonymous heterogeneous signcryption scheme can not only transfer data confidentially for users in heterogeneous cryptographic environment,but also provide privacy protection for users of both sending and receiving sides.The security of an anonymous ...

An Efficient Pipelined Technique for Signcryption Algorithms

, 2020
Signcryption algorithms are based on public key cryptography. The main advantage of signcryption algorithms is to provide both confidentiality and authenticity in one step. Hence, signcryption algorithms lower both communication and computation overheads.

An ID-based Hybrid Broadcast Signcryption Scheme with User Anonymity

工程科学与技术, 2013
:Broadcast signcryption can make the sender send multi messages to recipients by one operation. In order to efficiently solve the problems of low efficiency, large overhead and privacy security in “one-to-many” communication model, an ID-based broadcast ...

Certificateless KEM and Hybrid Signcryption Schemes Revisited [PDF]

, 2010
Often authentication and confidentiality are required as simultaneous key requirements in many cryptographic applications. The cryptographic primitive called signcryption effectively implements the same and while most of the public key based systems are ...

Signcryption secure against linear related-key attacks

, 2014
A related-key attack (RKA) occurs when an adversary tampers the private key stored in a cryptographic hardware device, and observes the result of the cryptographic primitive under this modified private key.

An Improved Certificateless Generalized Signcryption Scheme [PDF]

, 2013
Signcryption is basically a cryptographic primitive which provides both signature and encryption functions simultaneously, but it is not useful when only one of the function is required. Generalized Signcryption (GSC) is a special cryptographic primitive

A Traceable Ring Signcryption Scheme Based on SM9 for Privacy Protection

Information
To address the issues of insufficient privacy protection, lack of confidentiality, and absence of traceability mechanisms in resource-constrained application scenarios such as IoT nodes or mobile network group communications, this paper proposes a ...
