Hello,
I'm currently working on project (part of my Bachelor work) which will use to transfer very sensitive data over the network, and I'd like to use mesh networks to transfer this data. Additionally, it should also be possible for "normal people" to connect to this network (e.g. to surf internet). Preliminary, I've chosen BATMAN to build this network. But I've got a few questions regarding security of this solution:
1. Does BATMAN provide any method of *authenticating* nodes? As I've said earlier, sometimes transferred data will be highly sensitive (for example: information of patients health in hospital), so it's absolutely critical to not allow leaking this information. I can imagine situation when some fake nodes claim "Hey, I'm the server collecting this data"... I think this is also important when someone would try to destroy our mesh network by placing some fake nodes in it. 2. If point nr one isn't possible, maybe there is some other way to ensure security? I don't know too much about security or cryptography, but I can think of solutions such as openVPN or IPsec.
Generally, the goal is to assert security of transmitting some data *without* losing open characteristics of mesh network.
I will very thankful for any answers.
Kind regards, Adrian
