Sécurisation de la couche physique des communications sans contact de type RFID et NFC

Abstract : The arrival of the near field communications for transactions between portable remotely powered devices using RFID technology presents a problem. In fact, these communications provide not only an informative function but also a power and clock transfer function to the contactless device. Communication security is based on authentication protocols, security data integrity and confidentiality. Most of these remotely powered devices have low resources and then low defense against attackers. These features create a threat for contactless communications security and privacy data protection. Four types of attack exist: 1) Eavesdropping 2) Relay attack : Communication integrity can be in danger with the use of systems that can relay RFID reader commands to a RFID card. Transactions can be spied or even worse can be modified in case of a man-in-the-middle attack. 3) Skimming : Activation and reading of a contactless card from a distance. 4) The denial of service. The objective of this thesis is to find countermeasures using the physical layer in RFID contactless devices and in NFC mobile phones while avoiding the modification of actual standards.
