The future of integer factorization. Any signcryption scheme should have the following properties: Views Read Edit View history.

From Wikipedia, the free encyclopedia. A signcryption scheme typically digitall of three algorithms: Showing of 23 references. Gen generates a pair of keys for any user, SC is generally a probabilistic algorithm, and USC is most likely deterministic.

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 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.


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