Improved identity-based signcryption

Witryna13 gru 2024 · Encryption and digital signature are two basic security properties of any singcryption scheme. Such properties include integrity, non-repudiation, unforgeability and confidentiality. Forward secrecy and public verifiability are additional features that are provided depending upon the requirements. 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 …

Further improvement of an identity-based signcryption scheme in …

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. 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 … city with most air pollution https://uptimesg.com

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.

College of information, South China Agricultural University, Guangzhou, P.R. China. WitrynaIdentity-based signcryption was rst proposed by Malone-Lee [51], and was then intensively studied thereafter (e.g., [20,26,11,8]). The reader is referred to [43] for a good survey on ID-based signcryption. Identity-based signcryption has numerous promising applications.
