Privacy-Preserving Biometric Matching Using Homomorphic Encryption
Gaëtan Pradel, Chris Mitchell
Biometric matching involves storing and processing sensitive user information. Maintaining the privacy of this data is thus a major challenge, and homomorphic encryption offers a p…
Constructing orientable sequences
Chris J Mitchell, Peter R Wild
This paper describes new, simple, recursive methods of construction for orientable sequences, i.e. periodic binary sequences in which any n-tuple occurs at most once in a period in…
The (in)security of some recently proposed lightweight key distribution schemes
Chris J Mitchell
Two recently published papers propose some very simple key distribution schemes designed to enable two or more parties to establish a shared secret key with the aid of a third part…
Two closely related insecure noninteractive group key establishment schemes
Chris J Mitchell
Serious weaknesses in two very closely related group authentication and group key establishment schemes are described. Simple attacks against the group key establishment part of th…
Who Needs Trust for 5G?
Chris J Mitchell
There has been much recent discussion of the criticality of the 5G infrastructure, and whether certain vendors should be able to supply 5G equipment. The key issue appears to be ab…
Provably insecure group authentication: Not all security proofs are what they claim to be
