Simon Rastikian

Hello, world!

My name is Simon Rastikian and I am a student at École Normale Supérieure (ENS) in Paris. I am currently on a 5 months internship in CryptoNext Security startup.
I am mostly interested in cryptology, security & privacy, and machine learning.
After I graduated from high school, I studied math and computer science at Université Pierre et Marie Curie (recently called Sorbonne Université) in Paris, then I got accepted in the ENS after my second year of bachelor.

Education

2020 Year of Ceasura - École Normale Supérieure
After my Master's 1 I discussed with my tutor at ENS David Pointcheval to take a year of caesura and do 10 months of internships in cryptology and computer security. This year has been divided into 2 months of internship extension in the University of Luxembourg, 5 months of internship in CryptoNext security in Paris, and final internship of 3/3.5 months is still unknown. I am currently searching for a research internship cryptology.

2019 Master's 1 - École Normale Supérieure
I followed few courses on the first semester and did a 5 months internship at the University of Luxembourg in the second semester.
Part of my coursework includes:

2018 Bachelor 3 - École Normale Supérieure
I got accepted in the École Normale Supérieure in the computer science departement.
I followed few courses in the first and the second semester and did a 2 months internship in the CNRS lab in Lorient.
Part of my coursework includes:

2017 Bachelor 2 - Université Pierre et Marie Curie
I integrated a one-year double-major course in mathematics and computer science.
Part of my coursework includes:

2016 Bachelor 1 - Université Pierre et Marie Curie
I started the first semester by doing some physics, mechanics, and chemistry. Then I switched in the second semester to studying mathematics and physics.
Part of my coursework includes:

Projects & Experiences

Internships

2019 - 2020 CryptoNext Security - Paris - 5 months, November-March
Supervisors: Jean-Charles Faugère & Ludovic Perret
Introduction to the cryptographic challenges brought by the future Quantum Computers. This includes the study of Quantum Resistant cryptographic algorithms based on Lattices and Mutivariate Polynomials. The aim is to help implement efficiently a Post-Quantum cryptography library using assembly language and C language.

2019 APSIA Group - University of Luxembourg - 7 months, March-October
Supervisors: Peter Y. A. Ryan & Peter B. Rønne
Performance an in depth security analysis of the Selene verifiable voting scheme. This includes the development of formal definitions of the appropriate security properties and threat models. Assistance with the development of a prototype of a variant of Selene for trials in the VOLT project in collaboration with Surrey, King’s College London and Electoral Reform Services.

2018 Lab-STICC - CNRS, Huygens research center in Lorient - 2 months, July-August
Supervisor: Arnaud Tisserand
An introduction to side channel attacks against Elliptic Curve algorithms. This included the study of the Simple Power Analysis (SPA) attack on the window Non-Adjacent Form (NAF) method for point multiplication. This algorithm was implemented in C language and was combined to the µ-NaCl (which implements the Curve25519 in ARM assembly) to be injected to the STM32L053R8 and then tested. As some complication occured, a combination of the Montgomery algorithm and the window NAF algorithm was created.

Projects

2019 The projects were done in the Information security, Networks and Software engineering courses.

2018 The projects were done in the Programming languages and compilation, Digital systems and Operating systems and computer networks courses.
