Password — For other uses, see Password (disambiguation). A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource (example: an access code is a type of password). The password… … Wikipedia
Password cracking — is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. The purpose of password cracking might be to help a user recover a… … Wikipedia
Password strength — is a measurement of the effectiveness of a password as an authentication credential. Specifically, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to correctly guess it. The… … Wikipedia
Password-based cryptography — generally refers to two distinct classes of methods:*Single party methods *Multi party methodsingle party methodsSome systems attempt to derive a cryptographic key directly from a password. However, such practice is generally ill advised when… … Wikipedia
Password manager — A password manager is software that helps a user organize passwords and PIN codes. The software typically has a local database or a file that holds the encrypted password data for secure logon onto computers, networks, web sites and application… … Wikipedia
Password-authenticated key agreement — In cryptography, a password authenticated key agreement method is an interactive method for two or more parties to establish cryptographic keys based on one or more party s knowledge of a password. Contents 1 Types 2 Brief history 3 See also … Wikipedia
Password length parameter — In telecommunication, a password length parameter is a basic parameter which affects password strength against brute force attack and so is a contributor to computer security. Password length parameters are related by the expression P = L imes R… … Wikipedia
password trap — n. A program or Web site that uses a legitimate looking interface to fool users into providing their passwords. Example Citation: According to David, Phishing scams are different than benign spam schemes that try to sell the user something or get … New words
One-time password — A one time password (OTP) is a password that is valid for only one login session or transaction. OTPs avoid a number of shortcomings that are associated with traditional (static) passwords. The most important shortcoming that is addressed by OTPs … Wikipedia
Brute-force attack — The EFF s US$250,000 DES cracking machine contained over 1,800 custom chips and could brute force a DES key in a matter of days. The photograph shows a DES Cracker circuit board fitted with 32 Deep Crack chips and some control chips. In… … Wikipedia
Timing attack — In cryptography, a timing attack is a side channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. The attack exploits the fact that every operation in a computer … Wikipedia
