I think a number of the apparent conflicts go away if you carefully track endorsement key pair vs endorsement certificate (signature on endorsement key by hw manufacturer). For example where it is said that the endorsement _certificate_ could be inserted after ownership has been established (not the endorsement key), so that apparent conflict goes away. (I originally thought this particular one was a conflict also, until I noticed that.) I see anonymous found the same thing. But anyway this extract from the CC PP makes clear the intention and an ST based on this PP is what a given TPM will be evaluated based on: http://niap.nist.gov/cc-scheme/PPentries/CCEVS-020016-PP-TPM1_9_4.pdf p 20: | The TSF shall restrict the ability to initialize or modify the TSF | data: Endorsement Key Pair [...] to the TPM manufacturer or designee. (if only they could have managed to say that in the spec).
