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.

Efficient and Forward-Secure Identity-Based Signcryption.

Witryna1 lut 2010 · The proposed certificateless signcryption scheme In this section, we propose a certificateless signcryption scheme secure against malicious-but-passive KGC attacks in the standard model. The proposed scheme involves three parties: a KGC, a sender with an identity u S and a receiver with an identity u R. Witryna6 mar 2024 · Signcryption requires less computational complexity, communication cost, and implementation effort. Moving ahead, Deng and Boa [ 4] suggested a scheme to reduce computational cost by up to 16% and communication cost by up to 85% when compared to the signature-then-encryption technique.

WitrynaWe propose a fully functional identity-based encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming a variant of the computational Diffie-Hellman problem. Our system is based on bilinear maps between groups. The Weil pairing on elliptic curves is an example of such a map. WitrynaThe adversary is able to obtain some secret information from side channel attacks, which further damages the security for the system. To resolve this issue, we provide a hierarchical identity-based online/offline encryption scheme which resists side ...
