| Summary | 0001984: [Smart3][OS12] About the Unifykey and TEE/REE usage of the Smart3 BFX-AT100 | ||||
| Description | Hi Kinbay INTEK/INNOPIA uses the TEE area as a provisioning method But BFX-AT100 still uses Unifykey method and SKB says it uses REE area. SKB's request for confirmation is as follows. 1) Is BFX-AT100 using REE area? - If you have any data(doc) on the current REE usage status, please share it with us. 2) BFX-AT100 has been updated up to OS12. Does BFX-AT100 have to use TEE on OS12? If BFX-AT100 doesn't have to use TEE in OS12, please share the supporting data. 3) In the case of the Keys (HDCP/widevien/playready....) used by the BFX-AT100 - which area of the memory map is it stored in? - Is the corresponding key area mounted separately? - Is the corresponding key area only readable or read/writeable? Maybe SKB will request additional confirmation. First of all, if there is anything confirmed above, please update it. ASAP Thank you YK.Jung | ||||

Hi YK, I have checked in the DTS that the UnifyKey setup is secure. ./common/arch/arm64/boot/dts/amlogic/g12a_s905x2_eagle_3g.dts line: 494, 527, 542 TEE: When key-device is set to secure, these keys are likely stored in the TEE REE: When key-device is set to normal or another non-secure setting, these keys are typically stored in the REE. The case of your question (HDCP/widevien/playready) are all set to secure. BR, Kinbay |

Hi Kinbay To briefly what you're saying STB uses UnifyKey, but some of the key(HDCP/widevien/playready) use TEE Is it correct? one more thing , do you know what the files below are ? console:/vendor/lib/teetz # ls -la total 2532 drwxr-xr-x 2 root shell 4096 2009-01-01 09:00 . drwxr-xr-x 10 root shell 12288 2009-01-01 09:00 .. -rw-r--r-- 1 root root 129040 2009-01-01 09:00 00d1ca22-1764-4e35-90aa-5b8c12630764.ta -rw-r--r-- 1 root root 170616 2009-01-01 09:00 2c1a33c0-44cc-11e5-bc3b-0002a5d5c51b.ta -rw-r--r-- 1 root root 131540 2009-01-01 09:00 526fc4fc-7ee6-4a12-96e3-83da9565bce8.ta -rw-r--r-- 1 root root 927080 2009-01-01 09:00 8efb1e1c-37e5-4326-a5d6-8c33726c7d57.ta -rw-r--r-- 1 root root 454316 2009-01-01 09:00 9a04f079-9840-4286-ab92-e65be0885f95.ta -rw-r--r-- 1 root root 688156 2009-01-01 09:00 e043cde0-61d0-11e5-9c26-0002a5d5c51b.ta -rw-r--r-- 1 root root 346044 2009-01-01 09:00 e043cde0-61d0-11e5-9c260002a5d5c5ca.ta -rw-r--r-- 1 root root 134340 2009-01-01 09:00 e92a43ab-b4c8-4450-aa12-b1516259613b.ta -rw-r--r-- 1 root root 129076 2009-01-01 09:00 ff2a4bea-ef6d-11e6-89cc-d4ae52a7b3b3.ta Thank you YK.Jung |

Hi Kinbay Thank you for feedback.. One more thing In the case of Smart3, the Unifykey / REE method is used from ATV9. It's maintained until now ( ATV12.) Please check whether the current status is in violation of Google ATV12's policy or rules. It would be better to have Google data(link) related to it Please check it Thank you YK.Jung |

Hi Kinbay 1) About #c16586 >> Please check whether the current status is in violation of Google ATV12's policy or rules. Please contact Taiwan's SoC or find Google Docs ( link.. ) 2) Where are the keys stored in the EMMC memory map? 3) Can I access the keys directly by using console / adb? I have to report the above 3 contents to SKB by tomorrow. Please check it and if there is anything confirmed above, please update it Thank you YK.Jung |

Hi Kinbay >> Please check whether the current status is in violation of Google ATV12's policy or rules. >>>> We checked with Amlogic, and they don't have the documents. then is there any official feedback from Amlogic that the current status(using Unifykey method at OS12) is ok? If you have any official feedback, please share it with us. Can FXN contact 3PL for an official answer about this? I'm not sure if it's better to check with 3PL or not. Please give us your opinion. Thank you YK.Jung |
