Method and apparatus for controlling country specific frequency allocation

摘要

A secure communication system is provided for transmitting a country specific frequency allocation in encrypted form between a host processor and a remote device. The secure communication system comprises a host processor and a remote device capable of communicating with the host processor over a communication link. The host processor has a plurality of stored data sets and a predefined encryption algorithm. Each one of the stored data sets comprises a country specific frequency allocation. The remote device has a unique identifier code and also has the predefined encryption algorithm. Responsive to the unique identifier code, the host processor provides a selected one of the plurality of data sets in encrypted form by utilizing the predefined encryption algorithm. The unique identifier code provides an encryption key for the predefined encryption algorithm. The remote device then decrypts the encrypted data set using the predefined encryption algorithm with the identifier code as a decryption key.
