Time-varying block codes for synchronisation errors: maximum a posteriori decoder and practical issues

Autor: Johann A. Briffa, Victor Buttigieg, Stephan Wesemeyer

Publikováno v: The Journal of Engineering (2014)

In this study, the authors consider time-varying block (TVB) codes, which generalise a number of previous synchronisation error-correcting codes. They also consider various practical issues related to maximum a posteriori (MAP) decoding of these code

Eavesdropping near-field contactless payments: a quantitative analysis

Autor: Thomas P. Diakos, Johann A. Briffa, Tim W. C. Brown, Stephan Wesemeyer

Publikováno v: The Journal of Engineering (2013)

This paper presents an assessment of how successful an eavesdropping attack on a contactless payment transaction can be in terms of bit and frame error rates, using an easily concealable antenna and low-cost electronics. Potential success of an eaves

Direct Anonymous Attestation (Daa) is a set of cryptographic schemes used to create anonymous digital signatures. To provide additional assurance, Daa schemes can utilise a Trusted Platform Module (Tpm) that is a tamper-resistant hardware device embe

An anonymous Single Sign-On (ASSO) scheme allows users to access multiple services anonymously using one credential. We propose a new ASSO scheme, where users can access services anonymously through the use of anonymous credentials and unlinkably thr

SimCommSys: Taking the errors out of error-correcting code simulations

Autor: Johann A. Briffa, Stephan Wesemeyer

Publikováno v: The Journal of Engineering (2014)

In this study, we present SimCommSys, a simulator of communication systems that we are releasing under an open source license. The core of the project is a set of C + + libraries defining communication system components and a distributed Monte Carlo
