Electronic article surveillance. Electronic article surveillance (EAS) is a type of system used to prevent shoplifting [1] from retail stores, pilferage of books from libraries, or unwanted removal of properties from office buildings. EAS systems typically consist of two components: EAS antennas and EAS tags or labels.
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
IEEE 802.1AE (also known as MACsec) is a network security standard that operates at the medium access control layer and defines connectionless data confidentiality and integrity for media access independent protocols. It is standardized by the IEEE 802.1 working group. [ 1]
Message authentication code. In cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity -checking a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
IEEE 802.11w is the Protected Management Frames standard for the IEEE 802.11 family of standards. Task Group 'w' worked on improving the IEEE 802.11 Medium Access Control layer. [ 1] Its objective was to increase security by providing data confidentiality of management frames, mechanisms that enable data integrity, data origin authenticity, and ...
Wi-Fi Protected Access ( WPA ), Wi-Fi Protected Access 2 ( WPA2 ), and Wi-Fi Protected Access 3 ( WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired ...
Wireless lock is a protection concept for authenticated LAN or WLAN network clients offered from various vendors in various functional shapes and physical designs. In contrast to wireless keys, wireless lock puts emphasis on automatic locking instead of just locking by time-out or unlocking. The wireless lock concept supports initialising the ...
