CURRENT APPROACHES IN MODERN CRYPTOLOGY

This work proposes a brief analysis of the different types of current approaches to modern cryptology in present days. Due to increased development of communications and IT technologies, the field of cryptography practical approaches exceeded your government / military / intelligence / bank, eventually passing the civil environment and / or private. This process has soared in recent years and the requirements of market economy have forced a trend towards standardization of the theory and practice in cryptology. From there follows a rapid dissemination, sometimes without authorized assessment any official post by a wide range of users, including the private sector. This purposes as stated above, we try an analysis of current patterns of cryptology approach to find action ways for national authorized entities to follow in the near future to synchronize efforts made in the same field of other countries and / or alliances or international organizations. Finally, it should be noted that we considered only the approach of the different types of entities of the cryptologic phenomenon, without regard to side - the scientific approach, which may be subject to other works.cryptology

EVALUATION OF CRYPTOGRAPHIC ALGORITHMS

This article represents a synthesis of the evaluation methods for cryptographic algorithms and of their efficiency within practical applications. It approaches also the main operations carried out in cryptanalysis and the main categories and methods of attack in order to clarify the differences between evaluation concept and crypto algorithm cracking.cryptology, cryptanalysis, evaluation and cracking cryptographic algorithms
