A simple approach to this is to use a pre-shared key. The PC and devices would all have the same key, which is used to encrypt and protect communications. This avoids public key crypto, which would be beneficial if the devices are low powered. However, while it protects against outside attackers, it doesn't protect devices and the PC from each other. You ...
It's rather hard to give a sensible answer without knowing what you are trying to acheive. Using self-signed certificates you'll get secure point to point communications, but there is no intrinsic authentication - I can walk into your office with a laptop using my own certificate and start connecting to your services. OTOH if you run your own certificate ...
Two answers: Is it Technically Possible? Yep. All things are technically possible, given enough time, money and ingenuity. You can create a new cryptographically linked model for identification, create new standards for how the identified entity is described, create a new back end to provide for issuing, revoking and verifying the proof of identity and ...
You keep using that word identification. I do not think it means what you think it does. The Internet moves bits, it does't care what those bits are. Obviously third party servers won't respect non-standard certificates, because, you know, "standard". Up to you what attributes you include since you are designing your own PKI. Don't design your own PKI.
