comment What is the purpose of “g” -> generator of the multiplicative group
Performance boots from a small "g" is related to the usual "square-and-multiply" algorithm for modular exponentiation. The "multiply" steps are "multiply by g", which will be more efficient if g is a small integer. Note, though, that with common window-based optimizations of that algorithm, more than 80% of the work is spent in the squarings, so the gain obtained by using _g_=2 (instead of any random integer) are slight. Still, if it can be done with no extra cost, there is no reason to refrain.

RSA is a cryptographic algorithm which does not operate in a cyclic group (at least, not as such).

comment Is there a secure way to create and distribute Shamir Secrets?
"Dynamically composing a secret that no-one knows, and decrypting it": that is called Diffie-Hellman, when you think about it. The "shares" are the private/public DH pairs for both participants, that they generate freely, and they build the shared secret by combining their private key with the public key from the peer.

I am not sure your question makes sense. Asymmetric encryption is about protecting the confidentiality of some data -- data which already exists. With group decryption, the collaborating private key owners recover the original plaintext, and they all get it; the point is that they do not reveal each other their key shares: further decryption will still need a threshold of key owners.

comment Can virus save to SIM Card?
"Rooting" a phone is often done with the computer equivalent of bashing through a door with a sledgehammer. Some unintended side-effects may occur. The symptoms you describe match more mundane bugs than a true virus. Modern virus don't remove some buttons or reboot phones; they either try to keep invisible, or, if they really want to spread mayhem, they destroy the phone a lot more effectively.

comment Is it Possible to use one commercial SSL Certificate to issue end user certs?
Some commercial CA do sell intermediate CA certificates (I once made such a deal with GlobalSign), but only through a heavy contractual agreement with constraints (e.g. they require that you store the private key in a HSM), and the price is non-negligible.
