A Survey of Attacks on Multivariate Cryptosystems

Feldmann, Adam (University of Waterloo, 2005)

This thesis provides a survey of the attacks on multivariate cryptosystems. We begin by providing an outline of the general multivariate cryptosystem. Proceeding from there, we show that even with this level of detail, ...
The Theory and Applications of Homomorphic Cryptography

Henry, Kevin John (University of Waterloo, 2008-08-27)

Homomorphic cryptography provides a third party with the ability to perform simple computations on encrypted data without revealing any information about the data itself. Typically, a third party can calculate one of the ...
Verification of Pipelined Ciphers

Lam, Chiu Hong (University of Waterloo, 2009-01-29)

The purpose of this thesis is to explore the formal verification technique of completion functions and equivalence checking by verifying two pipelined cryptographic circuits, KASUMI and WG ciphers. Most of current methods ...
Walking Onions: Scaling Distribution of Information Safely in Anonymity Networks

Komlo, Chelsea (University of Waterloo, 2020-08-07)

Scaling anonymity networks offers unique security challenges, as attackers can exploit differing views of the network’s topology to perform epistemic and route capture attacks. Anonymity networks in practice, such as ...
