Method of ensuring safe communication in untrustworthy networks and device for making the same

ufeffzau0159u00edzenu00ed to that method is made up of at least one computer client, the unsecured communication channel for the transmission of encrypted data, secure communication channel for the transmission of the encryption key, the u0161ifruju00edcu00edm between private and nedu016fvu011bryhodn oh, networks, the connection to the safe network and encryption device between a public network and a client device.method for secure data transmission in untrustworthy networks is carried out such that the data intended for transmission of the encrypted code is sufficiently safe to send an unshielded in encrypted state to broadband communication channel and there is no risk of its d eu0161ifrovu00e1nu00ed in the recognition of any unauthorised person.the key, which are dispatched data encrypted is one-off, generated for each link randomly and individually, its length is of the order of less than the length of the transmitted data, it is sent to the recipient via the slow safe and credible network not to b be the key during the transmission or use compromised. the validity of each key expires after terminating the connection.the recipient uses the key that received via the trusted network to decrypt the data taken from the network unreliable. in this way, there will also be the authenticity of data and at the same time, to avoid the possibility of such a targeted or manipulation of data during their transmission.
