Nowadays we use the 802.11i standard, which is considered safe for now. In 2010, the Hole 196 vulnerability of Group Transient Key was discovered, which allows an undetectable insider ARP poisoning attack. On this ground we have founded the possibility of malware injection into wireless communication with purpose of avoiding intrusion detection system. This(More)
This paper is focused on preventing relay attacks on contactless devices, such as contactless smart cards or Near-Field Communication (NFC) devices. Relay attacks can be prevented by the so called distance bounding protocols, which are based on restricting the round trip time to some limit. Distance bounding protocols protect against all theoretical(More)
Designing and implementing secure applications which use contactless communication link is difficult even when secure hardware is used. Many current proximity devices, such as contactless smart cards or near field communication devices, are verified to be highly secure; however, inappropriate protocol implementation may result in the leak of sensitive(More)
We present a method of automated vulnerability finding in protocols that use contactless smart cards. We focus on smart cards with contactless interface because they are simpler than their counterparts with contact interface and provide less functionality, which can be modeled more easily. Our method uses model checking to find possible attacks in a model(More)
Nowadays wireless networks are becoming important in personal and public communication. Most of them are secured by 802.11i standard with strong AES cipher - WPA2. In many cases an attacker has the ability to listen to all encrypted network traffic, which may become a potential intrusion. Each client in wireless network is vulnerable to a variety of threats(More)
