[4] proposed a new ideal of proxy sign-cryption by combining the notions of proxy signature and signcryption in 1999. But their scheme does not support provable security [22]. In 2004, Li and Chen [13] proposed the rst identity-based proxy signcryption scheme using bilinear ...
A Constructive Perspective on Signcryption Security - ETH Z
WebJan 1, 2024 · Here, we proposed an ECC-based proxy signcryption for IIoT (ECC-PSC-IIoT) in a fog computing environment. The proposed scheme is providing the features of signature and encryption in a single cycle to active the basic requirements of low computation and communication cost. WebDec 8, 2024 · Most of the existing signcryption schemes generate pseudonym by key generation center (KGC) and usually choose bilinear pairing to construct authentication schemes. The drawback is that these schemes not only consume heavy computation and communication costs during information exchange, but also can not eliminate security … how many large sea scallops in a pound

WebSigncryption scheme of Iqbal et al Recently, Iqbal et al [13] proposed a new signcryption scheme for firewalls. The proposed scheme is based on elliptic curve cryptography. An elliptic curve over a finite field F p consists of the points satisfying the equation y2 = x3 + ax + b mod p, where a, b belongs to F p (the multi- WebMar 26, 2024 · The proposed BaaCA-based signcryption scheme includes three different entities: a sender, a recipient, and the blockchain. (1) Sender: a sender called Alice, with her private/public key pair , is sending data to a specified recipient. First, the data are split into two parts: and . Note that the privacy-sensitive part of is put into and the other remaining … WebJan 31, 2024 · A proxy signcryption [6-8] is a cryptographic algorithm that merges the idea of signcryption and algorithm with a proxy signature. In cryptography, signcryption is a cryptographic algorithm that achieves the functionality of both confidentiality and authentication in a single reasonable step with better performance than a traditional … howard university general education electives
