16.18 Configure AES Content Protection
AES (Advanced Encryption Standard) content protection is a solution to protect content during the
satellite transmission. The protection is implemented at DVB-S2(X) baseband frame level. The
modulator will encrypt the content before transmission. To receive the content, the demodulator
must be able to decrypt the received signal. The encryption and decryption process is based on
content keys. The decryptor is only authorized to receive the content when the correct content key is
loaded on the demodulator. (AES is a symmetric encryption method, meaning that the encryption
and decryption key must be the same to setup a secure end -to- end communication.)
With content key we mean an encrypted key.
Furthermore, AES content protection is a fully transparent security solution that guarantees the
transport stream at the output of the decryptor to be bit-per-bit identical to the one at the input of the
encryptor. This guarantees to use the content in a single frequency network after satellite
transmission.
AES protects transport streams or IP data, independently of the encapsulation used.
The security mechanism implemented is however NOT suited for applications
requiring very strong security, such as banking data exchanges, military secrets,
highly sensitive information, video feeds that needs to be kept confidential for a long
time.
