Knowledge and skills (P: prerequisite; D: desirable, but not necessary): Communication protocols (P); Cryptography (P); Information theory (P); Analytical way of thinking (P); Cryptographic protocols (D); Quantum cryptography (D); Quantum computing (D); Programming abilities (D).

Security of information is one of the main tasks in our days. The desire for protection of health records, personal data, and communications is a great opportunity to advance the technology for that. One of the most effective and reliable ways to protect data spread through a communication media is the use cryptography. Classical crypto methods are symmetric and asymmetric ones. The PKI is also a developing area.

The next level of development in cryptography – quantum cryptography – is a big challenge for universities, researchers, technical labs (it started there), organizations and industry (lasers, equipment). This new area takes in a different level the protection of data. The basis is not a mathematical but all the idea is based on the specific feature of photons – the polarization.

Questions that need answers

Student teams will need to identify and provide more details about specific technologies which can be used within quantum cryptography:

  • What are the main issues in the security of information from engineering point of view?
  • What is the basis of cryptography, main challenges and algorithms to implement it?
  • What models of a whole quantum cryptosystem (blocks and subsystems) exist?
  • What is the technology behind the quantum cryptography?
  • What equipment is needed to perform it?
  • What are quantum cryptography protocols?
  • What are quantum computers?
  • What protocols are used in quantum computing?
  • Which attacks and vulnerabilities against the cryptosystem and the cryptoprotocol exist?
  • Technology used – prices and curent situation on the market for main parts of the quantum machines;
  • Cost of the devices and elements for quantum computing and cryptosystems;
  • Existing business models in the domain of cryptosystems.
  • What will be the impact of such a big change in the cryptography system model?
  • What will be the impact on the market, for example of computers?
  • How can one enterprise for quantum computers or quantum cryptosystem components work?
  • What will be the qualification of the people and working environment?
