New Proofs for
HMAC was proved in [3] to be a PRF assuming that (1) the underlying compression function is a PRF, and (2) the iterated hash function is weakly collision-resistant. However, recent...

Hash Functions and RFID Tags: Mind the Gap
Abstract. The security challenges posed by RFID-tag deployments are wellknown. In response there is a rich literature on new cryptographic protocols and an on-tag hash function is ...

A fast real-time memory authentication protocol
We propose a new real-time authentication scheme for memory. As in previous proposals the scheme uses a Merkle tree to guarantee dynamic protection of memory. We use the universal...

HMAC is a randomness extractor and applications to TLS
In this paper, we study the security of a practical randomness extractor and its application in the tls standard. Randomness extraction is the first stage of key derivation functi...

Limits of Constructive Security Proofs
The collision-resistance of hash functions is an important foundation of many cryptographic protocols. Formally, collision-resistance can only be expected if the hash function in f...

Slide Attacks on a Class of Hash Functions
This paper studies the application of slide attacks to hash functions. Slide attacks have mostly been used for block cipher cryptanalysis. But, as shown in the current paper, they ...

Bucket Hashing and its Application to Fast Message Authentication
We introduce a new technique for constructing a family of universal hash functions. At its center is a simple metaphor: to hash a string x, cast each of its words into a small numb...

Design Validations for Discrete Logarithm Based Signature Schemes
A number of signature schemes and standards have been recently designed, based on the Discrete Logarithm problem. In this paper we conduct design validation of such schemes while t...

Efficiency of Data Structures for Detecting Overlaps in Digital Documents
This paper analyses the efficiency of different data structures for detecting overlap in digital documents. Most existing approaches use some hash function to reduce the space req...
