Witryna1 sty 2008 · The ID-based broadcast signcryption (IDBSC) is a scheme that allows multiple broadcasters to securely broadcast messages to authorized receivers. Using a pay-TV system as an example, we may refer a broadcaster to a program or channel which has been subscribed by a user. 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. Witrynauser’s identity information. 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. dancing with the stars week three elimination
