Hash chain - Open Access .click

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.

Improved Scalable Hash Chain Traversal

Lecture Notes in Computer Science, 2003
Yaron Sella recently proposed a scalable version of Jakobsson’s algorithm to traverse a hash chain of size n. Given the hash chain and a computation limit m (k=m+1 and \(b=\sqrt[k]{n}\)), Sella’s algorithm traverses the hash chain using a total of kb memory. We improve the memory usage to k(b-1).

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 ...
