Low efficiency and high cost of such summation, and the case that any arbitrary scheme cannot guarantee security. In cryptographysigncryption is a public-key primitive that simultaneously performs the functions of both digital signature and encryption.

Imai, “How to construct efficient signcryption schemes on elliptic curves”Information Processing Letters, Vol. Any signcryption scheme should have the following properties: Elliptic Curve Cryptosystems Neal Koblitz 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.
Signcryption provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately. This paper has highly influenced other papers. 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.

A signcryption scheme typically consists of three algorithms: Signcryption Search for additional papers on this topic.

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.

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. In public key schemes, a signcryptiion method is to digitally sign a message then followed by an encryption signature-then-encryption that can have two problems: FranklinJacques PatarinMichael K.
Gen generates a pair of keys for any user, SC is generally a probabilistic algorithm, and USC is most likely deterministic.
