Currently searching the best possible Differential MITM attacks on SKINNY 64-192 with MILP !

Work in progress, don’t worry and don’t worry me, i’m a “force tranquille” ;).

Thesis

I am supervised by Dr Naya-Plasencia and Dr Derbez for “Optimizing cryptanalysis of symmetric primitives” with the funding of the ERC “SoBaSyC”.
My goal is to encode some informatic tools in order to optimize the cryptanalysis of current symmetric primitives! For now I am focusing my self on coding a MILP tool to found optimize differential Meet in the Middle attacks.
I also look at the use of precomputed hash tables to improve cryptanalysis.

Conferences and Spring School

Mar 10-14, FSE Spring school, Roma :

I attended FSE Spring Shcool organized by CASA, Ruhr-Universität Bochum. With lessons about :

• Boolean Function by Anne Canteaut
• Linear and Differential Cryptanalysis by Tim Beyne
• Automating Tools for symmetric-key Cryptanlysis by Maria Eichlseder
• Security of encryption modes by Bart Mennink
• Aritmetization oriented cryptanlysis by Leo Perrin

Mar 15 : First Workshop on Symmetric Key Cryptanalysis Automation and Modelling (SKCAM), Roma.

Mar 17-21 : 25th Fast Software Encryption Conferences (FSE), Roma.

I didn’t presented but i hope that I was at least a good lion at the rump session :)
