In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase. [1] Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables ), by vastly growing the size of table needed for a successful attack. [2] [3] [4] It also helps protect passwords that ...
Database encryption can generally be defined as a process that uses an algorithm to transform data stored in a database into "cipher text" that is incomprehensible without first being decrypted. [1] It can therefore be said that the purpose of database encryption is to protect the data stored in a database from being accessed by individuals ...
The LoTW system uses "secure" authentication using cryptographic key distribution. An amateur's computer-based logbook, in ADIF or Cabrillo format, have to be "signed" using a key obtained from ARRL. (Logbook data includes callsigns and locations of stations, contact time, frequency, and operating mode.)
Access to the database is restricted by a master password or a key file. Both methods may be combined to create a "composite master key". If both methods are used, then both must be present to access the password database. KeePass version 2.x introduces a third option—dependency upon the current Windows user.
Description RSA SecurID token (older style, model SD600) RSA SecurID token (model SID700) RSA SecurID (new style, SID800 model with smartcard functionality) The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 ...
Description. The input to the bcrypt function is the password string (up to 72 bytes), a numeric cost, and a 16-byte (128-bit) salt value. The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form:
SecureLog involves an active key provider, a managed data store and a verification provider. Active Key Provider An active key provider distributes active keys to subscribers. An active key contains encrypted data representing time and a private secret. An active key has a validity period that is set by the active key provider. Managed data store
Secure coding. Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities. Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1] Through the analysis of thousands of reported vulnerabilities ...
