I am a one person company (OPC) that does research in both cryptography and cryptanalysis with the aim to create new products and/ or services.
Develop a new algorithm.
Algorithm development consists in the design, analysis, implementation and experimentation of an original algorithm. Both cryptography and cryptanalysis require efficient routines or very specific programming codes. Due to the fact that we are always dealing with some form of mathematics, I personally use the proprietary software Mathematica from Wolfram Research Inc. to develop a new algorithm.
