Title: Methods for Constructing Hash Functions and their Security

Hash functions are an important primitive for achieving cryptographic protocols. For example, a random oracle, which is a mathematical primitive, is often instantiated with a hash function. Techniques for constructing hash functions and analyzing their security have been rapidly developed owing to the SHA-3 competition. This talk first introduces methods for constructing a hash function from a given primitive. Next, definitions of security and typical attacking methods are mentioned. Finally, some recent topics are introduced.
