Field |
| Description |
|
|
|
ds_des_key_table |
| Table showing downstream DES keys. |
|
| |
ds_des_cbc_iv_table | Table of downstream DES Cipher Block Chaining mode information. | |
|
|
|
ds_des_sid_table |
| Table showing the SID values to be enabled for DES encryption. |
|
|
|
ds_des_sid_enable |
| Controls which SID entries in the SID table are enabled for encryption. In the above |
|
| example, none of the entries are enabled for encryption. |
|
|
|
ds_des_ctrl |
| Control register that controls the operating mode of the downstream DES engine. |
|
|
|
ds_des_sv |
| DES security version register; the range of the version field in the Baseline Privacy |
|
| Interface (BPI) extended headers that will be accepted by the hardware. High byte is |
|
| upper limit, low byte is lower limit. The Cisco uBR900 will accept versions 0 to 15. |
|
| |
ds_unencrypted_length | Specifies the number of bytes that will be unencrypted at the beginning of the MAC | |
|
| frame. 0x0C means the first 12 bytes are not encrypted, which is what the DOCSIS |
|
| Baseline Privacy specification calls for. |
|
|
|
us_des_key_table |
| Table showing upstream DES keys. |
|
| |
us_des_cbc_iv_table | Table of upstream DES Cipher Block Chaining mode information. | |
|
|
|
us_des_ctrl |
| Control register that controls the operating mode of the upstream DES engine. The |
|
| value 0x24 means that the upstream is configured to enable decryption and to use CBC |
|
| mode. |
