Dictionary attack in cryptography
Web1)If two files have the same hash, this guarantees that the files are the same. 2)Hashed passwords are vulnerable to dictionary attacks. 3)DES encryption became breakable when flaws were found in the S-box substitution algorithm. 4)Asymmetric cryptography sidesteps the key distribution problem. 5)Private and public keys need to be kept secret. WebAttacks are typically categorized based on the action performed by the attacker. An attack, thus, can be passive or active. Passive Attacks The main goal of a passive attack is to obtain unauthorized access to the information. For example, actions such as intercepting and eavesdropping on the communication channel can be regarded as passive attack.
