LINGUISTIC FEATURES OF A SECURE PASSPHRASE
Keywords:
passphrase, passphrase entropy, passphrase lexical composition, passphrase syntax, passphrase mnemonicsAbstract
Password authentication remains one of the most popular methods of user authorization in corporate systems, social networks, and various applications. The article touches upon the urgent problem of ensuring the reliability of user passwords capable of resisting modern hacker methods of password cracking, including the brute force attack technique. A passphrase is considered to be the most reliable type of password and linguistic techniques of structuring a secure passphrase that can increase its information entropy are analyzed. These techniques include combining words having no evidently common semantic context, not observing the rules of English Grammar, using words from different languages and transliterations.
