Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.
Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography.SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa).
Visual Studio Code, commonly referred to as VS Code, [8] is a source code editor developed by Microsoft for Windows, Linux, macOS and web browsers. [ 9 ] [ 10 ] Features include support for debugging , syntax highlighting , intelligent code completion , snippets , code refactoring , and embedded version control with Git .
Whereas SSH transmits a stream of bytes in each direction (from server to client or client to server) using TCP, Mosh runs a terminal emulator at the server to figure out what should be on the screen. [2] The server then transmits this screen to the client at a varying frame rate, depending on the speed of the network. [8]
The SCP program [8] is a software tool implementing the SCP protocol as a service daemon or client. It is a program to perform secure copying. It is a program to perform secure copying. Perhaps the most widely used SCP program is the OpenSSH command line scp program, which is provided in most SSH implementations.
The SSH developers have stated that the major impact of the attack is the capability to degrade the keystroke timing obfuscation features of SSH. [ 6 ] The designers of SSH have implemented a fix for the Terrapin attack, but the fix is only fully effective when both client and server implementations have been upgraded to support it. [ 1 ]
[1]: §8 A single user agent may act as both UAC and UAS for different transactions: [1]: p26 for example, a SIP phone is a user agent that will be a UAC when making a call, and a UAS when receiving one. Additionally, some devices will act as both UAC and UAS for a single transaction; these are called Back-to-Back User Agents (B2BUAs).
The on-line textbook: Information Theory, Inference, and Learning Algorithms, by David J.C. MacKay, contains chapters on elementary error-correcting codes; on the theoretical limits of error-correction; and on the latest state-of-the-art error-correcting codes, including low-density parity-check codes, turbo codes, and fountain codes.
