Position-based proxy signcryption

2015 IEEE/CIC International Conference on Communications in China (ICCC), 2015
Position-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.

Incrementally Executable Signcryptions

2014
We 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 ...

Security with Signcryption

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 Proxy Signcryption Schemes

Applied Mechanics and Materials, 2012
Identity-based encryption and signature schemes that allow any pair of users to communicate securely and to verify each other's signatures without verifying certificate. A signcryption is a primitive that provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately ...

Identity-based searchable attribute signcryption in lattice for a blockchain-based medical system

Frontiers of Information Technology & Electronic Engineering
Electronic healthcare systems can offer convenience but face the risk of data forgery and information leakage. To solve these issues, we propose an identity-based searchable attribute signcryption in lattice for a blockchain-based medical system (BCMS ...

ECDSA-Verifiable Signcryption Scheme with Signature Verification on the Signcrypted Message

2008
In 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.
