Automated Security Proof for Symmetric Encryption Modes
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
We presents a compositional Hoare logic for proving semantic security of modes of operation for symmetric key block ciphers. ...
We were able to use our method to verify semantic security of several encryption modes including Cipher Block Chaining (CBC), Cipher Feedback mode (CFB), Output Feedback (OFB), and Counter mode (CTR). ...
Other works try to encode security of symmetric encryption modes as a non-interference property for programs with deterministic encryption. ...

In this paper, we improve on a previous result by Gagné et al. [11] for automatically proving the semantic security of symmetric modes of operation for block ciphers. ...
Our method can be used to verify the semantic security of all the encryption modes that could be proven secure in [11] , in addition to a few new modes, such as Propagating Cipher-Block Chaining (PCBC) ...
An extensive discussion on different security notions for symmetric encryption and a proof of the CBC mode of encryption is presented in [3] . ...

Since the seminal work of Dolev and Yao, it has been realized that this latter approach enables significantly simpler and often automated proofs. ...
Since the 1980s, two approaches have been developed for analyzing security protocols. One of the approaches relies on a computational model that considers issues of complexity and probability. ...
The Cryp-toVerif tool can also be used not only to automate security proofs of protocols but also to automate security proofs of cryptographic primitives, reducing their security to standard cryptographic ...
