Reviewer: Phillip Hallam-Baker Review result: Ready We need the capability, the text is readable and there is a formal proof. What more could we ask for? The document provides a mechanism for protecting encrypted data by constructing a symmetric key from the combination of a key agreement value constructed in the normal fashion and a shared secret. This construction provides protection against quantum cryptanalysis. Application of the scheme is outside the scope of the document and is likely to be challenging as the scheme has to rely on the shared secret not being exposed in any form vulnerable to quantum cryptanalysis.
