Cryptanalysis
The process of decrypting coded messages without being told the key is called cryptanalysis.
The correct answer is Cryptanalysis.
Cryptanalysis is the process of decrypting coded messages without being told the key. It involves studying the cipher and its components to identify weaknesses or patterns that can be exploited to decipher the message. Cryptanalysts use various techniques, such as frequency analysis, pattern recognition, and statistical analysis, to break the encryption and reveal the original message.
To arrive at this answer, you can follow these steps:
1. Read and understand the question carefully. Focus on the keyword, which is decrypting coded messages without being told the key.
2. Consider the options provided: Cryptography, Cryptanalysis, and Cryptology.
3. Cryptography refers to the practice of secure communication through encryption and decryption.
4. Cryptology is a broader term that encompasses both cryptography and cryptanalysis.
5. Cryptanalysis specifically involves decrypting codes or ciphers without knowing the key.
6. Therefore, Cryptanalysis is the appropriate answer to the question.
