Plaintext Checkable Signcryption
2015Digital signature guarantees the authenticity and encryption ensures the confidentiality of a transmitted message. Signcryption, as the name indicates, is a primitive which serves both these purpose with added efficiency and features. In this paper, we introduce a variant of signcryption called Plaintext Checkable Signcryption PCSC, which extends ...

Certificateless Signcryption in the Standard Model
Wireless Personal Communications, 2016Signcryption can realize encryption and signature simultaneously with lower computational costs and communicational overheads than those of the traditional sign-then-encrypt approach. Certificateless cryptosystem solves the key escrow problem in the identity-based cryptosystem and simplifies the public key management in the traditional public key ...

ECDSA-Verifiable Signcryption Scheme with Signature Verification on the Signcrypted Message
2008In this paper, we propose a signcryption scheme which provides all the following properties at the same time. (1) forward security: the private key of a sender does not help any attack to break the confidentiality of any signcrypted message generated by the sender.

Incrementally Executable Signcryptions
2014We present the concept of incrementally executable signcryptions, which is a generalization of traditional on-line/off-line signcryption and facilitates optimizing the sender’s off-line computation. With an incrementally executable signcryption scheme, the sender can activate signcryption process incrementally by its given sequential input: the sender ...

On the Security of a Group Signcryption Scheme from Distributed Signcryption Scheme
2005Signcryption denotes a cryptographic method, which can process encryption and digital signature simultaneously. So, adopting such schemes, computational cost of encryption and signature compared to traditional signature-then-encryption can be reduced to a great extent. Based on the existing distributed signcryption schemes, Kwak and Moon proposed a new

Cryptoanalysis of Two Signcryption Schemes
2009 Fifth International Conference on Information Assurance and Security, 2009Certificateless PKC and self-certified PKC are two new public key systems. They remove the necessity of certificate to ensure the authentication of the user's public key in CB-PKC and also overcome the inherent key escrow problem in IB-PKC. Recently, Zhang et.al proposed a self-certified signcryption scheme, and Wu et.al gave a certificateless ...

Signcryption can provide improvements on efficiency for public-key cryptographic protocols over more traditional cryptographic mechanisms that offer security functions separately. Notably, applying signcryption in protocols where message confidentiality, integrity, and authenticity are all required is expected to result in protocols with better ...

Position-based proxy signcryption
2015 IEEE/CIC International Conference on Communications in China (ICCC), 2015Position-based cryptography has attracted lots of researchers' attentions. In mobile Internet, there are lots of position based security applications. For the first time, one new conception, position-based proxy signcryption is proposed. Based on a secure positioning protocol, one model of position-based proxy signcryption is proposed.

SSRN Electronic Journal, 2014
Signcryption is a recently newer technology that is still in the process of being developed and made completely efficient. The purpose is to take the previous sign then encrypt method but by killing two birds with one stone. The technology is a scheme which can produce secret and authenticated messages sent between different parties.

Identity-Based Transitive Signcryption
2014Transitive signatures allow a signer to authenticate a graph in such a way that given two signatures on adjacent edges (i, j) and (j, k), anyone with public information can compose a signature on edge (i, k). In all existing transitive signature schemes, to prevent signature exposure, a secure channel is required between the signer and the recipient to
