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 2015 · In this paper, we propose a new privacy-enhancing group signcryption scheme that provides: unforgeability, confidentiality, ciphertext and sender anonymity, traceability, unlinkability,...

WitrynaThe improved scheme has shorter ciphertext size than the ZYZZ scheme. We then prove that the improved scheme satisfies confidentiality, unforgeability, anonymity and authenticata- ... Several ID-based signcryption schemes have been proposed so far, e.g. [4,6,7,8,16,19]. In addition, many variations of ID-based signcryption were … WitrynaSeveral signcryption schemes proposed in the literature are known to lack semantic security, and semantically secure signcryption schemes tend to be more computationally expensive. In fact, devising an efficient signcryption scheme providing both public verifiability and forward security was until now an open problem. In this … Witryna23 sty 2005 · The idea of signcryption is to provide a method to encrypt and sign data together in a way that is more efficient than using an encryption scheme combined … includis.mdc
