Formal and informal translation and interpretation for immigrants and asylum seekers

As of 2011 there were over 50,000 migrants, who speak a language other than English or Irish at home, residing in Northern Ireland. Many of these individuals do not possess adequate levels of English language proficiency in order to access services. Research funded by the Northern Ireland Inclusion and Diversity Service was conducted to determine the home-school connections of culturally and linguistically diverse families in Northern Ireland. It revealed that there are a wide variety of ways that translation and interpretation services are offered for families not fluent in English within the school settings. Drawing upon the findings from the research in Northern Ireland, this presentation provides an overview of the types of translation and interpretation taking place in Northern Ireland; the advantages and disadvantages of each; and recommendations for agencies utilizing both formal and informal translation and interpretation. The presentation also includes references to work in this area in other contexts, as well as specific guidelines for agencies using both formal and informal translation and interpretation. These guidelines help ensure that the translations are conducted in a professional manner for all agencies providing services.

Time-Independent Discrete Gaussian Sampling for Post-Quantum Cryptography

As the development of a viable quantum computer nears, existing widely used public-key cryptosystems, such as RSA, will no longer be secure. Thus, significant effort is being invested into post-quantum cryptography (PQC). Lattice-based cryptography (LBC) is one such promising area of PQC, which offers versatile, efficient, and high performance security services. However, the vulnerabilities of these implementations against side-channel attacks (SCA) remain significantly understudied. Most, if not all, lattice-based cryptosystems require noise samples generated from a discrete Gaussian distribution, and a successful timing analysis attack can render the whole cryptosystem broken, making the discrete Gaussian sampler the most vulnerable module to SCA. This research proposes countermeasures against timing information leakage with FPGA-based designs of the CDT-based discrete Gaussian samplers with constant response time, targeting encryption and signature scheme parameters. The proposed designs are compared against the state-of-the-art and are shown to significantly outperform existing implementations. For encryption, the proposed sampler is 9x faster in comparison to the only other existing time-independent CDT sampler design. For signatures, the first time-independent CDT sampler in hardware is proposed.
