Hi,
I'm setting up a SGX DCAP enviroment for test purpose.My working machine supports SGX1 and the system is ubuntu18.04.I have build and installed PCCS but when I run PCKIDRetrievalTool to verify,I got this problem:
Error: unexpected error happend during sending data to cache server.
pckid_retrieval.csv has been generated successfully, however the data couldn't be sent to cache server!
Then I check the PCCS log file which presents the Error message:
[error]: PCK selection library returned 12
[error]: Error: No cache data for this platform.
at Proxy.getPckCertFromPCS (/opt/intel/sgx-dcap-pccs/services/logic/commonCacheLogic.js:232:11)
at async ReqCachingMode.registerPlatforms (/opt/intel/sgx-dcap-pccs/services/caching_modes/cachingMode.js:201:7)
at async Proxy.registerPlatforms (/opt/intel/sgx-dcap-pccs/services/platformsRegService.js:107:3)
at async postPlatforms (/opt/intel/sgx-dcap-pccs/controllers/platformsController.js:40:5)
[info]: 127.0.0.1 - - [09/May/2021:04:12:28 +0000] "POST /sgx/certification/v3/platforms HTTP/1.1" 404 32 "-" "-"
So I trace the souce code from PCCS where the error occurs to the SGX PCK Cert Selection Library linked by PCCS,and I get the root cause from function pck_cert_select,which returns the error code PCK_CERT_SELECT_PCK_NOT_FOUND ,with a comment by side: ”Raw Tcb is lower than all input PCKs". I'm not sure what the message exactly means.Does it means that the hardware of my machine is out of date?how can I solve this problem?
Any advice would be grateful,thanks!
