A post-detection decipherment strategy

This paper looks at the immense difficulties involved in trying to decipher the content of a signal, when the world's fears and expectations would be for immediacy of information. It is a reasonable assumption that having announced a signal is from an ET source that the next question will be "is there a message?" To put this task into context, we still have many scripts from our own antiquity that remain undeciphered, despite many serious attempts, over hundreds of years. So, given this, an algorithmic rationale, based on previous research into signal decipherment techniques, is presented. This phased approach will then provide an initial methodology for us attempting to unlock the content of an extra-terrestrial signal, whilst facilitating the dissemination of timely and accurate information to an expectant world.
