Unfortunately , to use the shared key one must reconstruct it at a single location. Thus , secret sharing is inappropriate for our purposes. Our system is designed to be easy to embed into existing applications. Thus it is in general beneficial to distribute the security tasks as much as possible. This is an interesting topic for future research.
Performance is a major concern for multicast security applications.
Thus , it is beneficial, in general, to distribute the security tasks as much as possible. This is an interesting topic for future research. Performance Performance is a major concern for multicast security applications. The technique described above of sharing the secret key such that it can be used without reconstruction at a single location is known as Threshold Cryptography. An important question left out of the above discussion is key generation.
