Introduction to Provable Security Models, Adversaries, Reductions Cryptography / Cryptology “from   Greek   κρυ πτός   kryptós , "hidden, secret"; and  γράφειν graphein , "writing", or  Clarity Security Models . Creating a security model that is overly complex and difficult to modify and maintain is easy to do when trying to implement tight security within Clarity. In this session, you will learn some key concepts when designing and implementing security. Additionally, Rego’s team of experts will share tips and tricks for automating security, as well as ways to monitor the Clarity rights that individuals have..
