Researchers at Carnegie Mellon University say that a wayfinding smartphone app and a smart suitcase that warns blind users of impending collisions can help people with visual disabilities navigate air...
On the impossibility of efficiently combining collision resistant hash functions
resistant hash functions efficiently combining
2015/8/5
Let H1, H2 be two hash functions. We wish to construct a new hash function H that is collision resistant if at least one of H1 or H2 is collision resistant. Concatenating the output of H1 and H2 clear...
The Collision Security of Tandem-DM in the Ideal Cipher Model
Collision Security Tandem-DM Cipher Model
2012/12/3
We prove that Tandem-DM, which is one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resistance in the ide...
