ifconfig (short for interface config) is a system administration utility in Unix-like operating systems for network interface configuration.. The utility is a command-line interface tool and is also used in the system startup scripts of many operating systems.
Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...
ISO/IEC 9797-1 Information technology – Security techniques – Message Authentication Codes (MACs) – Part 1: Mechanisms using a block cipher [1] is an international standard that defines methods for calculating a message authentication code (MAC) over data.
It alerts the client to wait for a final response. The message consists only of the status line and optional header fields, and is terminated by an empty line. As the HTTP/1.0 standard did not define any 1xx status codes, servers must not [note 1] send a 1xx response to an HTTP/1.0 compliant client except under experimental conditions. 100 Continue
sudo retains the user's invocation rights through a grace period (typically 5 minutes) per pseudo terminal, allowing the user to execute several successive commands as the requested user without having to provide a password again. [21] As a security and auditing feature, sudo may be configured to log each command run.
In cryptography, a cipher block chaining message authentication code (CBC-MAC) is a technique for constructing a message authentication code (MAC) from a block cipher.The message is encrypted with some block cipher algorithm in cipher block chaining (CBC) mode to create a chain of blocks such that each block depends on the proper encryption of the previous block.
Using MAC = H(key ∥ message ∥ key) is better, but various security papers have suggested vulnerabilities with this approach, even when two different keys are used. [ 1 ] [ 7 ] [ 8 ] No known extension attacks have been found against the current HMAC specification which is defined as H ( key ∥ H ( key ∥ message )) because the outer ...
ethtool is the primary means in Linux kernel-based operating systems (primarily Linux and Android) for displaying and modifying the parameters of network interface controllers (NICs) and their associated device driver software from application programs running in userspace.
