How to Build a Hash Function from Any Collision-Resistant Function
Recent collision-finding attacks against hash functions such as MD5 and SHA-1 motivate the use of provably collision-resistant (CR) functions in their place. Finding a collision ...

Non-trivial Black-Box Combiners for Collision-Resistant Hash-Functions Don't Exist
A (k, )-robust combiner for collision-resistant hash-functions is a construction which from hash-functions constructs a hash-function which is collision-resistant if at least k of ...

Compression from Collisions, or Why CRHF Combiners Have a Long Output
A black-box combiner for collision resistant hash functions (CRHF) is a construction which given black-box access to two hash functions is collision resistant if at least one of th...
