Signcryption is digiyal relatively new cryptographic technique that is supposed to perform the functions of digital signature and encryption in a single logical step and can effectively decrease the computational costs and communication overheads in comparison with the traditional signature-then-encryption schemes.

Gen generates a pair of keys for any user, SC is generally a probabilistic algorithm, and USC is most likely deterministic. Showing of extracted citations. Topics Discussed in This Paper. From This Paper Figures, diital, and topics from this paper.

In public key schemes, a traditional method is to digitally sign a message then followed by an encryption signature-then-encryption that can have two problems: This paper has highly influenced other papers.

In cryptographysigncryption is a public-key primitive that simultaneously performs the functions of both digital signature and encryption. From Wikipedia, the free encyclopedia. Imai, “How to construct efficient signcryption schemes on elliptic curves”Information Processing Letters, Vol.

A signcryption scheme typically consists of three algorithms: This page was last edited on 26 Januaryat Encryption and digital signature are two fundamental cryptographic tools that can guarantee the confidentialityintegrityand non-repudiation. Signcryption provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately.

This is the reason why a random session key is used for each message in a hybrid encryption scheme but for a given level of security i. Abdul HaleemM P Sebastisan Semantic Scholar estimates that this publication has 1, citations based on the available data.

This means that at least some aspect of its efficiency for example the computation time is better than any hybrid of digital signature and encryption schemes, under a particular sugncryption of security.

Any signcryption scheme should have the following properties: Low efficiency and high cost of such summation, and the case that any arbitrary scheme cannot guarantee security.

Note that sometimes hybrid encryption can be employed instead of simple encryption, and a single session-key reused for several encryptions to achieve better overall efficiency across many signature-encryptions than a signcryption scheme but the session-key reuse causes the system to lose security under even the relatively weak CPA model.
