Cryptography Crossword Clue: “A system of writing or signaling that uses symbols to conceal information from unauthorized parties.”
The key term to solve this cryptography crossword clue is “cipher”. A cipher is a method or device used for encrypting and decrypting messages. It involves substituting letters or numbers with others in such a way that only those who know the key can read the message. Ciphers have been used throughout history to protect sensitive information, and today they are still widely used to secure online communications.
There are many different types of ciphers, each with its own strengths and weaknesses. Some common examples include:
-
Substitution ciphers, where each letter is replaced with another according to a fixed rule. For example, A could be replaced with B, and so on.
-
Transposition ciphers, where the order of letters in a word is changed according to a fixed rule. For example, every other letter could be reversed.
-
Stream ciphers, where each letter is encrypted based on its position in the message stream. This type of cipher is particularly vulnerable to attacks if the key is compromised.
-
Block ciphers, where multiple letters are processed at once and then combined to produce a single encrypted block. This type of cipher is more secure than stream ciphers but also requires more processing power to decrypt.
In order to solve this cryptography crossword clue, you would need to know that the answer is “cipher”, which refers to any method or device used for encrypting and decrypting messages. By understanding how ciphers work, you can protect your sensitive information from unauthorized parties.
