WitrynaIn this paper we describe a new identity-based signcryption (IBSC) scheme built upon bilinear maps. This scheme turns out to be more efficient than all others proposed so … Witryna5 lis 2012 · In 2006, LI Fagen et al. proposed an efficient identity based signcryption scheme and declared that this scheme had the attributes of privacy, unforgeability, p …

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. WitrynaImproved Identity-Based Signcryption Abstract.

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 · To make up for this flaw, in this paper, an improved IBSC scheme is proposed and is shown to be really secure in the standard model. In our improvement, a random string is embedded into the signcrypted message during executing instructions of the signcryption algorithm. cinemark rated rWitrynaSigncryption was first initialized by Zheng [ 1] in 1997 to implement the function of digital signature and public key encryption simultaneously with better efficiency than the … cinemark recreio shoppingWitryna1 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. diabetic women\u0027s shoes salecinemark provo towneWitrynaCertificateless public key cryptography eliminatescertificate management in traditional public key infrastructure and solves the key escrow problem in identity-based cryptography.
