Cryptanalytic attacks
Cryptanalytic attacks mean compromising keys by way of decipherment to find out the keys. The goal of cryptanalysis is to decipher the private or secret key. The amount of information provided to the analyst as well as the type of information provided determines the type of attacks possible.
The methods of cryptanalytic attacks
The following six are the possible attack scenarios. Candidates are advised to understand the key differences between the different types of attacks:
- The cipher text only attack: This refers to the availability of the cipher text (encrypted text) to the cryptanalyst. With large cipher text data, it maybe possible to decipher the cipher text by analyzing the pattern.
- The known-plain text attack: When a cryptanalyst obtains cipher text as well as the corresponding plain text, then this type of attack is known as the known-plaintext attack. In this scenario, even if the data is small, it is possible to understand the algorithm.
- The chosen-plain text...
