Necessary and Sufficient Conditions for CollisionFree Hashing
 Journal of Cryptology
, 1995
"... This paper determines an exact relationship between collisionfree hash functions and other cryptographic primitives. Namely, it introduces a new concept, the pseudopermutation, and shows that the existence of collisionfree hash functions is equivalent to the existence of clawfree pairs of pseudo ..."

Collisionfree hashing from lattice problems
 Electronic Colloquium on Computational Complexity (ECCC) 3
, 1996
"... Abstract. In 1995, Ajtai described a construction of oneway functions whose security is equivalent to the difficulty of some well known approximation problems in lattices. We show that essentially the same construction can also be used to obtain collisionfree hashing. This paper contains a selfco ..."

Practical and ProvablySecure Commitment Schemes from CollisionFree Hashing
 in Advances in Cryptology  CRYPTO96, Lecture Notes in Computer Science 1109
, 1996
"... . We present a very practical stringcommitment scheme which is provably secure based solely on collisionfree hashing. Our scheme enables a computationally bounded party to commit strings to an unbounded one, and is optimal (within a small constant factor) in terms of interaction, communication, a ..."

Does Secure TimeStamping Imply CollisionFree Hash Functions?
"... Abstract. We prove that there are no blackbox reductions from CollisionFree Hash Functions to secure timestamping schemes, which means that in principle secure timestamping schemes may exist even if there exist no collisionresistant hash functions. We show that there is an oracle relative to wh ..."

A new paradigm for collisionfree hashing: incrementality at reduced cost
 In Eurocrypt97
, 1997
"... We present a simple, new paradigm for the design of collisionfree hash functions. Any function emanating from this paradigm is incremental. (This means that if a message x which Ihave previously hashed is modi ed to x 0 then rather than having to recompute the hash of x 0 from scratch, I can quick ..."

Chisel: A storageefficient, collisionfree hashbased network processing architecture
 In Proceedings of The 33rd Annual International Symposium on Computer Architecture (ISCA 33
, 2006
"... Longest Prefix Matching (LPM) is a fundamental part of various network processing tasks. Previously proposed approaches for LPM result in prohibitive cost and power dissipation (TCAMs) or in large memory requirements and long lookup latencies (tries), when considering future linerates, table sizes ..."
