Question

What kinds of threats exist for a cryptographic system?

Answer 1

There are three traditional types of attacks, and they are as follows:

1. Ciphertext-only attack: With this type of attack, only the ciphertext is known to the attacker. But if this particular individual is well-trained in statistics, then he or she can use various statistical techniques to break the ciphertext back into the plaintext
2. Known-plaintext attack: This occurs when the hacker knows some aspect of either the letter pairings; thus, they can consequently crack the ciphertext back into the plaintext
3. Chosen-plaintext attack: With this type of attack, the hacker can choose the plaintext and view the encrypted output which is being transmitted across the network medium. From this, they can reverse-engineer it back into its ciphertext form in an attempt to figure out the specific encryption scheme
