WebB. Constructive Cryptography Maurer and Renner’s Abstract Cryptography framework [26], [27] proposes a top-down paradigm for developing a theory of cryptography. In the conventional bottom-up approach, the notions of algorithms, complexity, and efficiency are fixed before the security of cryptographic constructs can be defined. WebWe propose an abstract approach to modeling system communication in Constructive Cryptography that avoids this problem. Our approach is suitable for mechanized verification and we use CryptHOL, a framework for developing mechanized cryptography proofs, to …
