In this paper we design several double length hash functions and study their security properties in the random oracle model. We design a class of double length hash functions (and ...
This paper contains techniques for enhancing the strength of any cryptographic hash function. For an "ideal", traditional hash function with an m-bit result, the complex...
This paper proposes spongent – a family of lightweight hash functions with hash sizes of 88 (for preimage resistance only), 128, 160, 224, and 256 bits based on a sponge construc...

In many applications, it is often desirable to extract a consistent key from a multimedia object (e.g., an image), even when the object has gone through a noisy channel. For examp...
