Provably Secure Mobile Key Exchange: Applying the Canetti-Krawczyk Approach

Practical use of the Canetti and Krawczyk approach to development of proven secure key exchange protocols is explored. The suite of protocols that can be developed using existing building blocks is discussed. An additional building block is provided by proving a new protocol secure in the ideal model of the approach. In the application area of wireless protocols it is shown that the best existing protocols can be matched with versions carrying security proofs. We conclude that building a library of building blocks will allow protocols with proven security to become the norm rather than the exception.
