The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux. LUKS implements a platform-independent standard on-disk format for use in various tools.
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes , or to reboot a computer without corrupting the filesystem . [ 1 ]
In Knoppix, a union between the file system on the CD-ROM or DVD and a file system contained in an image file called knoppix.img (knoppix-data.img for Knoppix 7) on a writable drive (such as a USB memory stick) can be made, where the writable drive has priority over the read-only filesystem. This allows the user to change any of the files on ...
Multiple keys: Whether an encrypted volume can have more than one active key. Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2 or Argon2. Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of.
In computer operating systems, union mounting is a way of combining multiple directories into one that appears to contain their combined contents. [1] Union mounting is supported in Linux, BSD and several of its successors, and Plan 9, with similar but subtly different behavior.
In cryptography, a shared secret is a piece of data, known only to the parties involved, in a secure communication. This usually refers to the key of a symmetric cryptosystem . The shared secret can be a PIN code , a password , a passphrase , a big number, or an array of randomly chosen bytes.
S/KEY is a one-time password system developed for authentication to Unix-like operating systems, especially from dumb terminals or untrusted public computers on which one does not want to type a long-term password. A user's real password is combined in an offline device with a short set of characters and a decrementing counter to form a single ...
GNOME Keyring is a software application designed to store security credentials such as usernames, [2] passwords, [2] and keys, together with a small amount of relevant metadata. The sensitive data is encrypted and stored in a keyring file in the user's home directory .
