A new key management protocol for remote sensing satellite with multi ground stations

The key management in remote sensing satellites is the most critical and important part in the security scheme in general and especially in case of multi ground stations. These ground stations may be under official contract to receive the data from the satellite for particular period of time. The problem with the schemes is if any ground station leaks the key information to the other ground station whose official contract is expired the encryption schemes fails. Further if the satellite service provider leaks the key information to the intruder, the symmetric key schemes fails. This paper solves the key management problem of encryption scheme in remote sensing satellite. The solution is a new key management protocol uses both traditional security verification methods and new orbital parameter verification method.
