I encountered a nice paper regarding analysis and consideration on which encryption algorithm it’s best suited for use in the space by space ship and equipments.
The paper has been done by the Consultative Committee for Space Data Systems that’s a consortium of all space agency around that cumulatively handled more than 400 mission to space.
Read the paper Encryption Algorithm Trade Survey as it gives interesting consideration and comparison between different encryption algorithms.
Obviously the finally selected algorithm is AES, while KASUMI (used in UMTS networks) was avoided.
