FranklinJacques PatarinMichael K. 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. In public key schemes, a traditional method is to digitally sign a message then followed by an encryption diggital that can have two problems: This page was last edited on 26 Januaryat Showing of extracted citations.
Signcryption – Wikipedia
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.
Gen generates a pair of keys for any user, SC is generally a probabilistic algorithm, and USC is most likely deterministic. References Publications referenced by this paper. From This Paper Figures, tables, and topics from this paper.

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.
