Classified information

One of the best ways to preserve classified information is to guarantee proper labeling by carefully marking all classified and sensitive items. This can aid in preventing illegal access, disclosure, or misuse of the information, as well as indicating the level of protection and management necessary.

What is Encryption

Encryption is the process of converting information into an unreadable format that can only be decrypted by authorized individuals with the appropriate key. 

Encryption can safeguard classified information from illegal access, disclosure, or misuse, and it is required when dealing with classified data in electronic form.

How to Encrypt classified information?

There are various encryption methods available, including 

• symmetric encryption
• asymmetric encryption
• hybrid encryption

Symmetric encryption is fast and efficient since it uses the same key to encrypt and decrypt data. Asymmetric encryption encrypts and decrypts information using a pair of keys, one public and one private, and is more secure but slower. 

Hybrid encryption combines the two methods, employing asymmetric encryption to exchange the symmetric key and then symmetric encryption to encrypt and decrypt the data.

For example, the United States government encrypts material up to the Top Secret level using the Advanced Encryption Standard, also known as AES, with 128-bit, 192-bit, or 256-bit keys. Other countries’ encryption standards and algorithms for classified material may differ.

Some Basic Steps To Encrypt Classified Information:

Here is a summary of what you need to do:

1. Select an encryption method, standard, and algorithm appropriate for the level of categorization and type of information to be encrypted. For more information, see your security policy or authority.
2.  Create or receive the encryption key or keys that will be used to encrypt and decrypt the data. You must keep the key or keys secure and hidden and only disclose them to those who have a legitimate need to know.
3. Use an encryption tool or software that is compatible with the encryption method, standard, and algorithm you’ve chosen. A hardware device, such as a USB drive or a smart card, or a software application, such as a file encryption program or an email encryption program, can be used to encrypt your information.
4. Check to ensure that your data is encrypted and unreadable by unauthorized parties. This can be accomplished by opening the encrypted data using a different tool or software, or by sending it to a test receiver who lacks the encryption key or keys.
