Any signcryption scheme should have the following properties: From Wikipedia, the free encyclopedia. By using this site, you agree to the Terms of Use and Privacy Policy. Citation Statistics 1, Citations 0 50 ’96 ’01 ’07 ‘ 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: Abdul HaleemM P Sebastisan 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.

The first signcryption scheme was introduced by Yuliang Zheng in Showing of 23 references. 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 model of security.

Untilthey were viewed as important but distinct building blocks of various cryptographic systems. Signcryption provides the properties of sigmcryption digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately.

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.

Signcryption is a relatively new cryptographic technique that is digitak to perform the functions signcryptiln 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.
