Multi Level Security:
IP Security: DoS/Ddos, Flooding attacks and Port Scanning
Application Security: Malformed messages, Directory Harvesting and Call Fraud
Content Security: Eavesdropping, Call Hijacking and Media Injection
Gradually building up to be calls over the blockchain.
Blockchain will be the Fibre Optics cable connecting the users.
The system basically never stores the encryption keys so they can't be retrieved, It uses 256AES encryption based on open standards.
However, engineers are also looking at using HSM's for key management
http://en.wikipedia.org/wiki/Hardware_security_module which Vodafone uses for parts of their network.
So the storage system also encrypts data within it, and then applies a seal to that data. the seal server sits in a separate location - and can be used for external validation - so it could sit with a bank Regulator, or any other Institute. It then also has multiple layers of security to get to the data!! So far on penetration testing it hasn't been breached and it has been pen tested by every major bank.
In addition the way the storage is created basically makes it massive processing grid where it can crunch data, the way it could be understood it is that in effect it acts like a pseudo quantum processor, where it can process multiple data flows, simultaneously within the grid.
So the theory on it is that it can not only process data, but it can store it as well, therefore it could be used to run an exchange whilst processing all the data within tight regulatory controls, but could possible also be used as a cold storage system for any digital currency and
"CREATE INSTANT TRANSACTIONS BASED ON THE SEAL ALLOCATED TO EACH TRANSACTION WITH TX ATTACHED TO IT"
So the principle of above is not only are calls encrypted but transactions can be sealed and stored enabling instant transaction in the same method of storing for telecommunications. "this is currently under review for testing with NXT2PAY" this therefore takes some of the TPS stress off the blockchain.
