Abstract
A communications system (40) comprises a first entity (42), a first encryption device (48) and a network (46). The first encryption device (48) is adapted to decrypt, using a first decryption algorithm, data sent from a first destination to said first entity via said network (46). The first encryption device (48) is adapted to pass network metric data concerning at least one route between said first entity and said first destination to said first entity without subjecting said network metric data to said first decryption algorithm.
Claims16
A communications system comprising a first entity, a first encryption device and a network, wherein said first encryption device is adapted to decrypt, using a first decryption algorithm, data sent from a first destination to said first entity via said network and to pass network metric data concerning at least one route between said first entity and said first destination to said first entity without subjecting said network metric data to said first decryption algorithm.
A method of operating a secure communications system in which one or more entities send data to one or more other entities of the system via a network, wherein at least some of said data is encrypted and decrypted using encryption and decryption algorithms, the method comprising the step of sending network metric data from said network to one or more of said entities without subjecting the network metric data to said decryption algorithm.
