@Blaze, do you have a source for this? Thanks.

comment Definition of a CSPRNG
Kind of, but the notion of 'statistical randomness' is already captured in the next-bit test (or distinguisher) condition, what I want to know is whether the second condition stated on Wikipedia is: (a) credible (is there a reliable source for this?) (b) necessary and sufficient for being a CSPRNG (c) well-defined/robust

@e-sushi, Thanks but I don't think this covers my question - I am seeking a robust definition of what it means to be theoretically cryptographically secure. It does not matter if it is not possible to prove the whether a particular implementation meets this definition of being CS, or whether other practical aspects undermine the theoretically security. For example, I can define what it means for a Turing Machine to halt, whilst it is not possible to decide whether a machine holds on a given input.
