Authentication in stealth distributed hash tables
No full textMost existing DHT algorithms assume that all nodes have equal capabilities. This assumption has previously been shown to be untrue in real deployments, where the heterogeneity of nodes can actually have a detrimental effect upon performance. We now acknowledge that nodes on the same overlay may also differ in terms of their trustworthiness. However, implementing and enforcing security policies in a network where all nodes are treated equally is a non-trivial task. We therefore extend our previous work on Stealth DHTs to consider the differentiation of nodes based on their trustworthiness rather than their capabilities alone

A secure key distribution protocol based on hash functions and a quantum-authenticated channel using 6DP (KDP-6DP)
No full textSecurity is the most tedious problem in highly sensitive communications. Quantum security is the key
issue in solving the problem. A key distribution protocol based on the use of hash functions is proposed.
The essential part of the protocol depends on sending a string of random characters from sender to
receiver. Then, a selected hash or a cascade of two hash functions and a long-term shared secret are used
to construct the key. Consequently, the session key is generated on-site by independently applying a hash
function on the random string at the sender and receiver sides. This protocol requires a reliable method of
authentication. Therefore, it is further proposed to use an out-of-band authentication methodology based
on the deterministic six-state quantum authentication protocol that is referred to as 6DP
Integrated-key cryptographic hash functions
No full textCryptographic hash functions have always played a major role in most cryptographic applications. Traditionally, hash functions were designed in the keyless setting, where a hash function accepts a variable-length message and returns a fixed-length fingerprint. Unfortunately, over the years, significant weaknesses were reported on instances of some popular ``keyless" hash functions. This has motivated the research community to start considering the dedicated-key setting, where a hash function is publicly keyed. In this approach, families of hash functions are constructed such that the individual members are indexed by different publicly-known keys. This has, evidently, also allowed for more rigorous security arguments. However, it turns out that converting an existing keyless hash function into a dedicated-key one is usually non-trivial since the underlying keyless compression function of the keyless hash function does not normally accommodate the extra key input. In this thesis we define and formalise a flexible approach to solve this problem. Hash functions adopting our approach are said to be constructed in the integrated-key setting, where keyless hash functions are seamlessly and transparently transformed into keyed variants by introducing an extra component accompanying the (still keyless) compression function to handle the key input separately outside the compression function. We also propose several integrated-key constructions and prove that they are collision resistant, pre-image resistant, 2nd pre-image resistant, indifferentiable from Random Oracle (RO), indistinguishable from Pseudorandom Functions (PRFs) and Unforgeable when instantiated as Message Authentication Codes (MACs) in the private key setting. We further prove that hash functions constructed in the integrated-key setting are indistinguishable from their variants in the conventional dedicated-key setting, which implies that proofs from the dedicated-key setting can be naturally reduced to the integrated-key setting.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
