An Improved Elegant Method to Re-initialize Hash Chains [PDF]
, 2005 Hash chains are widely used in various cryptographic systems such as electronic micropayments and one-time passwords etc. However, hash chains suffer from the limitation that they have a finite number of links which when used up requires the system to re-

Ramanujan graphs in cryptography [PDF]
, 2018 In this paper we study the security of a proposal for Post-Quantum Cryptography from both a number theoretic and cryptographic perspective. Charles-Goren-Lauter in 2006 [CGL06] proposed two hash functions based on the hardness of finding paths in ...

A Secure Communication Method Based on Message Hash Chain
Applied Sciences, 2022 Traditional network communication methods lack endogenous security mechanisms, which is the root cause of network security problems, e.g., spoofing identity and address forgery. This paper proposes a secure communication method based on the message hash chain, referred to as the chain communication method or MHC method. We use the message hash chain to

Energy-Efficient Hash Chain Traversal
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 A hash chain H for a one-way hash function h(·) is a sequence of hash values , where vn is a secret value, vi is generated by vi=h(vi+1) for i=n-1,n-2,...,0 an0d v0 is a public value. A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1≤i≤n.

IcebergHT: High Performance PMEM Hash Tables Through Stability and Low Associativity [PDF]
arXiv, 2022 Modern hash table designs strive to minimize space while maximizing speed. The most important factor in speed is the number of cache lines accessed during updates and queries. This is especially important on PMEM, which is slower than DRAM and in which writes are more expensive than reads. This paper proposes two stronger design objectives: stability
