Lacking easy access to entropy, some devices may use hard-coded keys to seed random generators, or seed random generators from easily guessed unique identifiers such as the device's MAC address. A simple study [which?] demonstrated the widespread use of weak keys by finding many embedded systems such as routers using the same keys. It was ...
MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. Each address can be stored in the interface hardware, such as its read-only memory , or by a firmware mechanism.
However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing. Essentially, MAC spoofing entails changing a computer's identity, for any reason. [1]
I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices .
The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
The processing keys at higher position in the tree than the given set of Device Keys are not reachable. A given set of Device Keys give access to a given set of Processing keys, it is to say to a given set of decodable MKB. This way, to revoke a given device key, the MKB needs only be encrypted with a Processing Key which is not reachable by ...
A flat-panel display (FPD) computer monitor A cathode-ray tube (CRT) computer monitor A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display , support electronics, power supply, housing , electrical connectors , and external user controls.
A device fingerprint or machine fingerprint is information collected about the software and hardware of a remote computing device for the purpose of identification. The information is usually assimilated into a brief identifier using a fingerprinting algorithm .
