Improved identity-based signcryption
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 ... 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.

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, … 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 …
WitrynaAn identity-based threshold signcryption scheme for multiple receivers is proposed. For the n specified receivers, the ciphertext can be decrypted and verified when arbitrary t or more receivers work together. The steps of the private keys extraction, ... Witryna1 maj 2010 · The concept of identity-based (ID-Based) cryptography was first introduced by Shamir [1] in 1984. Its basic idea is that the users can choose arbitrary strings, …

College of information, South China Agricultural University, Guangzhou, P.R. China. 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.
