ABSTRACT:
A system and method for providing security in data communication systems where multiple users are coupled to a common receiving system. The data is encrypted or otherwise encoded by a sender using a key. The encrypted data is then scrambled or otherwise encoded, and transmitted by the sender. The transmitted data is received at a receiver where it is descrambled or otherwise decoded. An authorized user decrypts or otherwise decodes the descrambled data using a key to retrieve clear data. The key itself is encrypted by the sender using an asymmetric encryption algorithm, and is then transmitted by the sender. The authorized user decrypts the encrypted key using the asymmetric encryption algorithm, and uses the key to decrypt the encrypted data.
