comment How to show the inner workings of ECC?
For mathematicians (who presumably know the basics of group theory), I'd avoid the pretty pictures. Instead, I'd approach it as "EC as an abstract group" angle; here's the group, here's how we do point multiplication, here's what the DLog problem is, see how it doesn't have any obvious solutions, here's the basic DH protocol...

comment Establish Trust By Signing Random Seed
If you use RSASSA-PKCS1_V1_5 signatures, you have to have padding; it's built into the protocol. As for how to protect against MITM, one obvious way would be to use the fact that the attacker cannot modify M; for example, do an (EC)DH exchange, and make M one of the public values; with that, the attacker can learn the value of M, but cannot learn the shared secret (and the key we use to encrypt/authenticate the rest of the exchange will be derived from the shared secret)
