Arbitrator2.0: Preventing Unauthorized Access on Passive Tags

IEEE Transactions on Mobile Computing, 2022
As the Ultra High Frequency (UHF) passive Radio Frequency IDentification (RFID) technology becomes increasingly deployed, it faces an array of new security attacks. In this paper, we consider a type of attack in which a malicious RFID reader could arbitrarily access the tags, e.g., retrieve or modify IDs or other data in the memory, via standard ...

Authorized! access denied, unauthorized! access granted

Proceedings of the 6th International Conference on Security of Information and Networks, 2013
Existing access control systems are mostly identity-based. However, such access control systems impose risks because recognized identity is not essentially an interpretation of good intentions of access. On the other hand, an un-identified individual might request access to suppress damage or prevent a catastrophic incident from happening.

Preventing Unauthorized Access on Passive Tags

IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018
As the Ultra High Frequency (UHF) passive Radio Frequency IDentification (RFID) technology becomes increasingly deployed, it faces an array of new security attacks. In this paper, we consider a type of attack in which a malicious RFID reader could arbitrarily modify the tags via standard commands, e.g., IDs or other data in the memory.

Robust Detection of Unauthorized Wireless Access Points

Mobile Networks and Applications, 2008
Unauthorized 802.11 wireless access points (APs), or rogue APs, such as those brought into a corporate campus by employees, pose a security threat as they may be poorly managed or insufficiently secured. An attacker in the vicinity may easily get onto the internal network through a rogue AP, bypassing all perimeter security measures. Existing detection

Unauthorized Access Offences in Cyberworld

2015
Computer hacking is the accessing of a computer system without the express or implied permission of the owner of that computer system (Bainbridge 2004, p. 381). A person who engages in this activity is known as a computer hacker and may simply be motivated by the mere thrill of being able to outwit the security systems contained in a computer.
