Anyone who knows what entropy means knows where the only true sources arise: physical processes. These include: - quantum effects - thermal noise - radioactive decay I cited two online services that provide true sources of entropy based on the first two of these - the first of which is digitally signed and escrowed, and both of which provide access to past values for verification. If we need more than that, perhaps I should submit a physics book as an RFC. Joe
