WebJan 1, 2001 · Abstract. This paper describes a simple candidate one-way hash function which satisfies a quasi-commutative property that allows it to be used as an accumulator. This property allows protocols to be developed in which the need for a trusted central authority can be eliminated. Space-efficient distributed protocols are given for document … WebGrain 128a. The Grain 128a stream cipher was first purposed at Symmetric Key Encryption Workshop (SKEW) in 2011 [1] as an improvement of the predecessor Grain 128, which added security enhancements and optional message authentication using the Encrypt & MAC approach. One of the important features of the Grain family is that the throughput can ...

WebMar 7, 2024 · Cryptographic accumulator can be divided into two types: symmetric accumulator and asymmetric accumulator. In the asymmetric accumulator, three … In cryptography, an accumulator is a one way membership hash function. It allows users to certify that potential candidates are a member of a certain set without revealing the individual members of the set. This concept was formally introduced by Josh Benaloh and Michael de Mare in 1993. See more There are several formal definitions which have been proposed in the literature. This section lists them by proposer, in roughly chronological order. Benaloh and de Mare (1993) Benaloh and de … See more • Cryptography • Zero-knowledge proof See more One example is multiplication over large prime numbers. This is a cryptographic accumulator, since it takes superpolynomial time to factor a composite number … See more Haber and Stornetta showed in 1990 that accumulators can be used to timestamp documents through cryptographic chaining. (This concept anticipates the modern notion of a … See more WebNov 7, 2024 · Cryptographic accumulators are a common solution to proving information about a large set S. They allow one to compute a short digest of S and short certificates of some of its basic properties, notably membership of an element. Accumulators also allow one to track set updates: a new accumulator is obtained by inserting/deleting a given … the westin hotel in dc
