This paper describes the study of cryptographic hash functions, one of the most important
classes of primitives used in recent techniques in cryptography. The main aim is the …

We consider a long standing problem in cryptanalysis: attacks on hash function combiners.
In this paper, we propose the first attack that allows collision attacks on combiners with a …

As users become increasingly aware of the need to adopt strong password, it hinders the
digital forensics investigations due to the password protection of potential evidence data. In …

Although very developed in many sectors (databases, filesystems), access control schemes
are still somewhat elusive when it comes to wireless sensor networks. However, it is clear …

We describe preimage attacks on several double-branch hash functions. We first present
meet-in-the-middle preimage attacks on RIPEMD, whose output length is 128 bits and …

The work in this thesis examines protocols designed to address the issues of tracing illegal
distribution of digital content in a fair manner. In digital content distribution, a client requests …

Recent attacks on hash functions start by constructing a differential characteristic. By finding
message pairs that satisfy this characteristic, a collision can be found. This paper describes …
