|
| () |
| Abstract: |
| We introduce one of the security strategies of CATV network,or the conditional access in this paper. Then, we discuss the concerned technologies including the system structure, encryption, scrambling and the key management. Finally, we point out the development of the conditional access in the CATV network. [WT5HZ] |
