RESUMO

The importance of security maintenance in critical information networks has been rising in recent times. Over the past decades, the utilization of cryptography tools, mainly those based on computationally intractable problems, was enough to ensure the security of communications systems. The development of the new information processing technique known as quantum computation and the theoretical and experimental results showed by this approach demonstrated that could be possible to cripple the current widely used cryptography techniques. This vulnerability represents a critical issue for networks where a security fault could be associated to a safety fault. An alternative for the current cryptography methods consists in the utilization of quantum systems to obtain a new cryptographic method. The new paradigm presented by this approach has solid principles even in the presence of unlimited computational capacity, including the scenario with availability of quantum computation. The aim of this work is the assessment of impacts that the development of quantum computation has over the current cryptographic methods security, the presentation and development of alternatives based on quantum cryptography protocols, and the development of a case study using the case of Aeronautical Telecommunication Network (ATN). This aim is reached by means of the development of a simulation environment that allows the evaluation of a quantum cryptography protocol behavior in an environment with mission critical requirements, like the ATN case.
