Determining Minimum Hash Width for Hash Chains

Proceedings of the Third Central European Cybersecurity Conference, 2019
Cryptographic hash functions are used in authentication, and repeated application in hash chains is used in communication protocols. In embedded devices, the width of hash values and the associated effort to evaluate the hash function is crucial, and hence the hash values should be as short as possible but should still be sufficient to guarantee the ...

Divisible Blind Signatures based on Hash Chains

International Journal of Computers and Applications, 2004
AbstractThis article presents an efficient divisible blind signature scheme that makes it possible to divide a blind signature with a specified value into a sequence of subsignatures with smaller values for a sequence of different designated verifications.

Hash Function Vulnerability Index and Hash Chain Attacks

2007 3rd IEEE Workshop on Secure Network Protocols, 2007
A hash chain is constructed by repeated hashing from an initial value. While it finds applications for network protocol design it also poses threats to hash function one-way and collision-free properties. We investigate the complexity of breaking hash function security properties by hash chain attacks using probabilistic algorithms.

IJTAG Integrity Checking with Chained Hashing

2018 IEEE International Test Conference (ITC), 2018
The JTAG port is a well-known vector for attacks that attempt to gain access to a chip’s internal circuitry. Such attacks may modify or extract proprietary data and can lead to misconfigured chips and IP theft. This paper uses a hash-based signature created through the history of the data shifted into and out of a device via IJTAG to provide a measure ...

Concurrent Chaining Hash Maps for Software Model Checking

2019 Formal Methods in Computer Aided Design (FMCAD), 2019
Stateful model checking creates numerous states which need to be stored and checked if already visited. One option for such storage is a hash map and this has been used in many model checkers. In particular, we are interested in the performance of concurrent hash maps for use in multi-core model checkers with a variable state vector size.

Hash chain based strong password authentication scheme

2016 13th International Bhurban Conference on Applied Sciences and Technology (IBCAST), 2016
The constant influence of passwords over all other methods of identity authentication is a key discomfiture to security examiners. Web technologies are gaining more and more fame day by day but the persistent survival and replication of password authentication schemes generate difficulties for end users.
