Abstract [eng] NFC technology is closely related with RFID solution and contactless smart cards. This technology can be used to create different types of systems operating in 13,56 MHz frequency, but it is being increasingly criticized for periodically detected security flaws. This lack of security in systems is most often associated with memory chips which are embedded in contactless smart cards. So the goal of this paper is to explore security properties of memory chips in NFC systems and to offer applicable security mechanisms which would allow increase chips security. This paper explores the possibilities of unauthorized access of information stored on “MIFARE Classic” data chips. Identify above mentioned data security problem in this paper offer by using concluded security assessment algorithm for 13,56 MHz systems. Vulnerability issues of “Crypto-1” cipher allowing illegal decryption of “MIFARE Classic” data chips is also being assessed in this paper. Such a security problem in other NFC based systems is being offered to overcome by concluded medium decryption time variation functions. The security of NFC and HF RFID systems operating in Lithuania is also being analyzed in this paper. Especially vulnerable KTU access control security is offered to be increased according by using the suggested system safety algorithm. However, paper provides the general safety requirements which should be used in any 13,56 MHz system with “MIFARE Classic” chips.
