INTERNSHIP 2022 (bachelor’s cycle)

Based on the protocol (No. 6775-6777/10.06.2022) for organizing the internship concluded between CiTi and the Faculty of Applied Sciences, during 27 June – 2 September 2022, the following students completed their internship within CiTi (Faculty of Applied Sciences, MIAI specialization, 3rd year), under the supervision of Assoc. Prof. PhD Emil Simion and Lect. PhD Corina Cipu.

 

The trainees developed skills in the following programming languages as part of the training activities: Python and LaTeX, and as a research activity they deepened the basic notions related to cryptology:

  • Hash functions
  • Blockchain
  • Elliptic curves

 

The internship resulted in PowerPoint presentations about what was learned and a C++ program related to elliptic curves.
