1. A device for performing bidirectional control in digital bidirectional communication, comprising:
- an interface block for converting a format of input downstream data to generate downward data;
a CPU which receives the downward data and realizes a MAC (Media Access Control) function; and
a TEK process block for receiving TEK (Traffic Encryption Key) process data obtained from the downward data, analyzing a data structure of the TEK process data, and performing decryption processing based on a result of the analysis.

Abstract
An interface block (11) converts the format of input downstream data (STRM). A CPU (12) receives the format-converted data (DIF) and realizes the MAC function. A TEK process block (13) receives TEK process data (DTEK) obtained from the data (DIF), analyzes the data structure of the TEK process data, and performs decryption processing based on a result of the analysis.
