Improved Identity-Based Signcryption - IACR

Witryna1 maj 2010 · In our improvement, a random string is embedded into the signcrypted message during executing instructions of the signcryption algorithm. Thus, only the intended receiver can decrypt the corresponding ciphertext with his private key to get the original message and the random string, and verify the ciphertext’s validation with them.

It uses attribute-based signcryption (ABSC) to achieve data conﬁdentiality and authentication. Under this model, attribute-based encryption gives the access policies for users and keeps the data conﬁdentiality, and the attribute-based signature is used for authentication of the primary ciphertext-integrity. cuddl duds women fleece
