Encryption code
From Halopedia, the Halo wiki
Template:FOF-1 An Encryption Code, otherwise known as an Encryption Key, is a cryptological encoding.
Cryptological Theory
Encryption only enables senders with the appropriate decryption devices to read secretive transmissions or documents. Persons or organizations that do not possess the appropriate decryption key to decrypt an encrypted file must result to a battery of cryptological techniques to decrypt a file, even using artificial cognitive computatory sources as powerful as AIs.
The sender will encrypt a piece and send it to the reciever, and will list both the public key and private key of the file. The public key is widely available, and was used to encrypt the file. The private key is available only to the reciever, and is used to decrypt the file.[1]
The Covenant and the United Nations Space Command both use encryption.
UNSC Usage
Encryption is placed on UNSC documentation or transmissions in order to maintain the level of secrecy demanded by the Transmission Classification. Encryption codes, like classifications, come in varying types, based on the importance of the information in the file.
Sometimes an AI will be required in order to decode the data.
- Encryption Code: NA: Transmissions without code are not classified at all and can be accessed by anyone at any time. Examples of this include the journals produced by UNSC Astrophysics.
- Encryption Code: Red: This code is used most of the time in military transmissions. Classification can be "Restricted," "Classified," or "Secret". The code is sometimes harder to crack, depending on how complex the scheme of the code can be. Examples of this code include the Cole Protocol.
- Encryption Code: GAMMA: This is a high level code. It is used on the most classified information and is likely to be an extremely complex code. It coincided with the classification of "Eyes Only Top Secret."
