Cryptography and Crypto-SystemsIn this section we shall describe what modern cryptographic methods are expected to achieve - the criteria of security they have to meet. It would be convenient if there were proofs of the security of a cryptographic algorithm but this is not so. At best they can be shown to resist the known methods of attack.

Protocols and Network InterconnectionAs the number of computer networks is increasing more and more, it will become more desirable to carry out interconnections between them.

Satellite Communications Systems and the European Project Stellaions served ranging from 100 upwards. The general method of operation of these systems is for the stations to beam up signals to the satellite at one frequency and for the satellite repeater to broadcast these signals down to all the stations using another frequency.
