Surveillance and the Crypto Wars: The End of Privacy?



Overview

This online lecture chronicles the conflict between citizens and states concerning unrestricted encryption access. We start with a brief overview of surveillance before examining the Crypto Wars, the subject of Dr Jarvis' first book. We will step through each of the three 'wars' to understand the key 'battles', including the Data Encryption Standard debates, the Key-escrow policy, and the impact of the Edward Snowden disclosures. Finally, we consider the future of encryption policy.
