Quantum computing threatens classical cryptography, leading to the search for stronger alternatives. The cryptographic approach based on lattices is considered as a viable option. Schemes with that approach use Gaussian sampling, a design which brings along two concerns: efficiency and information leakage. This work adresses those concerns in the RLWE formulation, for digital signatures. Efficiency mitigation uses the central limit theorem, and the Walsh–Hadamard transform, whereas the information leakage risk is reduced via isochronous implementation. Up to 223 samples are queried, and the results are compared against those of a cumulative distribution table sampler. Statistical metrics show the suitability of the presented sampler in a number of contexts.

Not without efforts I got this masters. As one can infere, starting to pursue such degree with 42 has required me to build a self-motivation foundation to begin with. An even harder task amid the global COVID-19 pandemic, and the very own life at fourty two. At some point during my lattice-based cryptography learning process, weird associated subjects started to pop up, and that has put me in a confusion state. I remember reading the expression "ring learning with errors", and thinking, as of where that had came from. It took me some time to figure out semantics, only to realize the bigger challenge before me. Luckily, the studied subject was fascinating enough, and also, I was surrounded by relevant people and organizations with valuable things to share, be it of emotional, technical or financial nature.For emotional support, thank you, beloved daughter Beatriz and beloved son Paulo. You have helped me in many ways. I've always had my motivation reaffirmed when we were together. I am also grateful for having been raised by my parents, who provided me with strength to face troublesome situations like this challenging adventure. Also, attending therapy sessions has proven to be effective in making self-motivation flourish. Thus, thank you, Mateus Pinheiro, for optimizing my insanity.Additionally, people endowed with outstanding knowledge has supported me in this work. Thank you, Prof.
