The gallery length filling function and a geometric inequality for filling length
filling length filling function
2015/8/26
We exploit duality considerations in the study of singular combinatorial 2-discs ("diagrams") and are led to the following innovations concerning the geometry of the word problem for finite presentati...
The Preimage Security of Double-Block-Length Compression Functions
Hash Function Preimage Resistance Block Cipher Beyond Birthday Bound Foundations
2012/12/4
We present new techniques for deriving preimage resistance bounds for block cipher based double-block-length, double-call hash functions. We give improved bounds on the preimage security of the three ...
