Question
Role of Certificate in OCS / LCS
I was trying to understand the cycle of certificate involvement in initiating connections of thick OCS client from my internal workstations to the OCS server.
I read that we can use both internal PKI or an external trusted RA certificate for this purpose. irrespective, there are two types of communication:
1. OCS Server in one pool to an OCS server in another pool.
2 OCS Communicator client to ocs server in their respective pools.
I read something here, but it doesn't come out very clearly:http://www.ocspedi
Would someone like to explain this in easy terms of Asymmetric keys and step by step encryption?
Thanks

OCS uses asymmetric key to encrypt its traffic using TLS. This identical to what you see when using HTTPS. Recent HTTPS implementation are using TLS, not SSL.
You can find excellent descriptions of how TLS and asymmetric encryption works on wikipedia:

And on the underlying PKI principles:

The Security Now! podcast explained the basis of this also very well. See http://www.grc.com/securit
It's episodes #34, #35 & #36 of April 2006. You can read the transcripts or listen to the mp3s.
If you have any detail which you can't grasp, just shout. It's not the easiest of topics, but once you 'get' it, it will make things a lot clearer.
