Kinakh I. Methods of parallel calculations and ground of level of cryptographic defence of information are in computer networks

A research object is the computer networks are for cryptoanalysis of the asymmetric systems of enciphering of information on the basis of the use of algorithm of Number field sieve (NFS) method; the aim investigation - the increase of defence of computer networks on the basis of base level of cryptographic defence and improvement of methods of parallel calculations in computer networks by kryptoanaysis on the basis of the distributed calculations; methods and equipments are analytical, experimental; results theoretical and practical - methods and tools which assure the increase of efficiency of testing process of the computer systems and their constituents due to reduction of time on the finding of the secret keys; novelty - first the parallel method of kryptoanalysis of the system of enciphering of information of RSA got subsequent development, due to the choice of the special a polynomial algorithm of the NFS method, that allows lowed common amount of operations of groups on the stages of sifting and treatment of matrix of largeness. Results used at Ternopil radiofactory "Orion". Drawing on results is recommended in the field of defence of information of computer networks.
