Cryptographic primitives in blockchains
WebDec 12, 2024 · Lightweight cryptographic solutions are required to guarantee the security of Internet of Things (IoT) pervasiveness. Cryptographic primitives mandate a non-linear operation. The design of a lightweight, secure, non-linear 4 × 4 substitution box (S-box) suited to Internet of Things (IoT) applications is proposed in this work. The structure of … Webtography. Blockchains provide both: new applications of existing cryptographic primitives (such as hash function, or zero-knowledge proofs), as well as, novel foundations on which new crypto-graphic primitives can be realized (such as fair-secure computation [ADMM14,BK14,CGJ+17], or, one-time programs [GG17]).

WebThe use of access control and cryptographic primitives are insufficient in addressing modern cyber threats all privacy and security concerns associated with a cloud-based environment. In this paper, the authors proposed a lightweight blockchain technique based on privacy and security for healthcare data for the cloud system. WebBlockchains use cryptographic primitives to secure underlying operations. These comprise hashes (using algorithms like SHA-256, Keccak 17 , RIPEMD-160) and asymmetric key cryptography primitives (ECDSA) to verify transactions and to derive user addresses.
