| Outline of Final Research Achievements |
Hash functions are efficiently computable and are important cryptographic primitive. Especially, hash chains, which repeatedly apply a hash function to an initial value, are one of the most important cryptographic techniques when we develop authentication protocols. In this work we proposed simple and efficient authentication schemes with several novel elaborate hash chains. Furthermore, we devise, for example, a key generation scheme and path authentication based on our hash chain constructions.
