Untilthey were viewed as important but distinct building blocks of various cryptographic systems. The first signcryption scheme was introduced by Yuliang Zheng in Signcryption is a 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.

Showing of extracted citations. 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: Signcryption provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately.


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.

Gen generates a pair of keys for any user, SC is generally a probabilistic algorithm, and USC is most likely deterministic. The future of integer factorization. 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.
