Chameleon: a Blind Double Trapdoor Hash Function for Securing AMI Data Aggregation [PDF]
, 2018 Data aggregation is an integral part of Advanced Metering Infrastructure (AMI) deployment that is implemented by the concentrator. Data aggregation reduces the number of transmissions, thereby reducing communication costs and increasing the bandwidth ...

Some Plausible Constructions of Double-Block-Length Hash Functions [PDF]
, 2006 In this article, it is discussed how to construct a compression function with 2 n-bit output using a component function with n-bit output. The component function is either a smaller compression function or a block cipher. Some constructions are presented which compose collision-resistant hash functions: Any collision-finding attack on them is at most ...

Attacks on Fast Double Block Length Hash Functions [PDF]
Journal of Cryptology, 1998 The security of hash functions based on a block cipher with a block length of m bits and a key length of k bits, where $k\leq m$ , is considered. New attacks are presented on a large class of iterated hash functions with a 2m -bit hash result which processes in each iteration two message blocks using two encryptions.

Blockcipher-Based Double-Length Hash Functions for Pseudorandom Oracles [PDF]
, 2012 PRO (Pseudorandom Oracle) is an important security of hash functions because it ensures that the PRO hash function inherits all properties of a random oracle in single stage games up to the PRO bound (e.g., collision resistant security, preimage resistant security and so on). In this paper, we propose new blockcipher-based double-length hash functions,

Securing Financial Transactions with a Robust Algorithm: Preventing Double-Spending Attacks
Computers, 2023 A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending ...

Electron contact interlayers for low‐temperature‐processed crystalline silicon solar cells
Progress in Photovoltaics: Research and Applications, EarlyView., 2023 In this study, a series of interlayers are trialed as electron‐selective contacts on crystalline silicon, including several materials that were previously untested in this application. Most of these interlayers were found to achieve mΩcm2‐scale specific contact resistivities.
