Analysis of RFID security and privacy by means of identification and authentication protocols

When analyzing the Radio Frequency Identification applications, one might think of two essential hierarchies: the structures aiming to offer security to an RFID system and the structures aiming to offer functionality means, with no security issues. One should know precisely the significance of these notions. Radio Frequency Identification represents an advanced wireless technology, which integrates an essential solution within the fields of intelligent chips and automation technologies. In this paper, four protocols based on updating the tags' identifiers by means of RFID readers will be compared, in order to carry out an analysis over the jeopardizing points that threaten the security and privacy of RFID systems. Cryptography signifies a way of creating RFID systems more secure. A chaotic matter is brought into discussion, by the following situations: to find out if it is a protocol of identification or authentication that is necessary, depending on various RFID applications or systems. Such analysis over RFID security has carried out wide thoughts.
