signcryption造句

例句与造句

1. The first signcryption scheme was introduced by Yuliang Zheng in 1997.
2. Any signcryption scheme should have the following properties:
3. Signcryption provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately.
4. A signcryption scheme typically consists of three algorithms : Key Generation ( Gen ), Signcryption ( SC ), and Unsigncryption ( USC ).
5. A signcryption scheme typically consists of three algorithms : Key Generation ( Gen ), Signcryption ( SC ), and Unsigncryption ( USC ).
6. It's difficult to find signcryption in a sentence. 用signcryption造句挺难的
7. Schemes based on these primitives provide efficient identity-based encryption as well as pairing-based signatures, signcryption, key agreement, and proxy re-encryption.
8. There are also many other signcryption schemes that have been proposed throughout the years, each of them having its own problems and limitations, while offering different levels of security and computational costs.
9. Zheng also proposed an elliptic curve-based signcryption scheme that saves 58 % of computational and 40 % of communication costs when it is compared with the traditional elliptic curve-based signature-then-encryption schemes.
10. 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.
11. Some widely known cryptosystems include PGP, etc . More complex cryptosystems include electronic cash systems, signcryption systems, etc . Some more'theoretical'cryptosystems include interactive proof systems, ( like zero-knowledge proofs ), systems for secret sharing, etc.
12. 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 . e ., a given model, say CPA ), a signcryption scheme should be more efficient than any simple signature-hybrid encryption combination.
13. 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.
