Brute force attacks are the simplest form of attack against a cryptographic system. In a brute force attack, the attacker simply guesses repeatedly at the encryption key until he or she stumbles upon the correct value for the key and gains access to the encrypted information. In this video, learn how attackers wage brute force attacks and how security professionals can protect against them.
- [Announcer] As long as cyber-security experts have used…encryption to protect sensitive information,…attackers have sought to undermine that security…and gain unauthorized access to that protected information.…Over the centuries, attackers have developed a number…of techniques designed to help them crack…cryptographic algorithms.…Brute-force attacks are the simplest form of attack against…a cryptographic system.…In a brute-force attack,…the attacker simply guesses repeatedly at the encryption key…until he or she stumbles upon the correct value for the key…and gains access to the encrypted information.…
Of course, guessing isn't easy,…and brute-force attacks can take a very long time…to complete successfully, if they ever succeed.…Brute-force attacks require very little information to wage.…The attacker simply needs to have an example…of encrypted ciphertext.…For this reason, brute-force attacks are also called…known ciphertext attacks.…Earlier in this course, I shared the example…of a simple shift cipher, that simply moves each of…
