Invited Talk
11:00-12:00 Blockwise-Adaptive Modes of Operation: A Tutorial
Antoine Joux

In this talk, we present the blockwise security paradigm for modes of operation. Blockwise security was introduced to reflect common practice, where messages are not encrypted as a whole under a mode of operation for a block cipher but instead processed block by block in a incremental manner. In this new setting, extra precaution are needed to guarantee the security of encryption.
Moreover, we show that, even with these extra precautions, attacks in the blockwise security model might become easier than attacks in the usual messagewise security model.
