Dynamic group Diffie-Hellman protocols for Authenticated Key Exchange (AKE) are designed to work in a scenario in which the group membership is not known in advance but where parti...

Matsui's linear cryptanalysis for iterated block ciphers is generalized by replacing his linear expressions with I O sums. For a single round, an I O sum is the XOR of a balan...
We propose a message recognition protocol which is suitable for ad hoc pervasive networks without the use of hash chains. Hence, we no longer require the devices to save values of ...
Prior approaches [15, 14] to building collusion-free protocols require exotic channels. By taking a conceptually new approach, we are able to use a more digitally-friendly communic...
Chosen-plaintext attacks on private-key encryption schemes are currently modeled by giving an adversary access to an oracle that encrypts a given message m using random coins that ...
