Practical Electromagnetic Template Attack on HMAC [chapter]

Pierre-Alain Fouque, Gaëtan Leurent, Denis Réal, Frédéric Valette
2009 Lecture Notes in Computer Science  
In this paper, we show a very efficient side channel attack against HMAC. Our attack assumes the presence of a side channel that reveals the Hamming distance of some registers.  ...  The secret key can be recovered using a "template attack" with a computation of about 2 32 3 κ compression functions, where κ is the number of 32-bit words of the key.  ...  Here, we focus on more practical attacks on HMAC.  ...

Differential Power Analysis of HMAC Based on SHA-2, and Countermeasures [chapter]

Robert McEvoy, Michael Tunstall, Colin C. Murphy, William P. Marnane
2007 Lecture Notes in Computer Science  
Using an implementation on a commercial FPGA board, we show that such attacks are practical in reality.  ...  In this paper, we describe a DPA attack strategy for the HMAC algorithm, based on the SHA-2 hash function family.  ...  We focus on SHA-256 in our attacks, because it is easier in practice to perform a side-channel attack on a 32-bit word than on a 64-bit word.  ...

EM Analysis in the IoT Context: Lessons Learned from an Attack on Thread

Daniel Dinu, Ilya Kizhvatov
2018 Transactions on Cryptographic Hardware and Embedded Systems  
When successfully applied on a Thread network, the attack gives full network access to the adversary.  ...  We choose the most feasible attack vector to build a complete attack that combines network specific mechanisms and Differential Electromagnetic Analysis.  ...  Experimental results show that in practice template attacks suffer from the variability caused by different devices or different acquisition campaigns [CK14] .  ...

The attacks are practical, non-invasive, and highly effective-even against complex and noisy systems where cryptographic computations account for only a small fraction of the overall power consumption.  ...  We also introduce approaches for preventing DPA attacks and for building cryptosystems that remain secure even when implemented in hardware that leaks.  ...  The MRED attack on RSA [25] is also a variant of this approach. Template attacks Template attacks [51, 52] seek to make maximal use of a small number of traces from a target device.  ...
