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 ...

Hash Function Vulnerability Index and Hash Chain Attacks [PDF]

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.

Infinite length hash chains and their applications

Proceedings. Eleventh IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises, 2003
Hash chains are used extensively in various cryptography applications such as one-time passwords, server-supported signatures and micropayments. In this paper, we present a method, called infinite length hash chains to improve the flexibility of this chaining idea by using public-key techniques.

Hash chains with diminishing ranges for sensors

International Journal of High Performance Computing and Networking, 2004
Sensors and other constrained devices periodically transmit small information packets motivating the study of hash chains with small domains and ranges. Hash chain based protocols use deferred disclosure and it is often assumed their hash functions are one-way, thus essentially unbreakable.
