Ciphertext
In space and astronautical engineering, ciphertext refers to the encrypted form of a message or data that has been transformed into an unreadable format using a cryptographic algorithm. This is done to ensure the confidentiality and integrity of the information being transmitted or stored. Ciphertext can only be decrypted and read by authorized parties who possess the key or password to unlock it. In space missions, ciphertext is used to protect sensitive information such as mission plans, spacecraft designs, and communication between ground stations and spacecraft. It is also used to secure data transmitted between satellites and ground stations, and to prevent unauthorized access to spacecraft systems and controls.
