Signcryption
WebApr 11, 2024 · Meanwhile, there are problems of tracking malicious users and protecting internal and external attackers in smart grid. In order to solve the issues described above, this paper proposes a certificateless linkable ring signcryption (CLRSC) scheme without bilinear pairing based on SM2. WebA related-key attack (RKA) occurs when an adversary tampers the private key stored in a cryptographic hardware device, and observes the result of the cryptographic primitive under this modified private key. In this paper, we consider the security of signcryption schemes under linear RKAs, where an adversary is allowed to tamper the private keys ...

WebJan 1, 2006 · For typical security parameters for high level security applications (size of public moduli = 1536 bits), signcryption costs 50% (31%, respectively) less in computation … Websigncryption using libsodium. An implementation of the Toorani-Beheshti signcryption scheme, instantiated over the Ristretto255 group. Why. Traditional authenticated encryption with a shared key allows two or more parties to decrypt a ciphertext and verify that it was created by a member of the group knowing that secret key.
WebApr 8, 2024 · We propose a proxy signcryption scheme for a multi-party setting, resistant to randomness leakage and setup attacks. Our scheme is an alternative to typical constructions, based on a double Schnorr signature approach, where the linear combination of long term secrets and ephemeral random values occurs both at the initiator and proxy … WebApr 3, 2024 · In particular, we first propose and demonstrate the security of the signature scheme cumulative signcryption (CL-A-SC) scheme in the random oracle model. The proposed CL-A-SC strategy, ...

WebSigncryption is a technique of performing signature and encryption in a single logical step. It is a secure and efficient technique of providing security between the sender and the receiver so that the data send by the sender should be made secure from various types of attacks such as desynchronization attacks, identity disclosure attack and spoofing attacks. fixed profitWebMar 21, 2007 · Signcryption is an asymmetric cryptographic method that provides simultaneously both message confidentiality and unforgeability at a low computational … fixed profit mileage ratesWebAbstract.
