Abstract:

The topic of side-channel attacks is one of the most important issues in
applied cryptography. In the literature, one can find many results on
high security systems like smart cards. However, until now we are not
aware of any side-channel analysis resistant implementation of AES on
automotive processors. For the first time, an efficient (32-bit
optimized) and secured (countermeasures against timing and power
analysis) AES implementation has been investigated on automotive platforms.

In this talk, i present an efficient and side-channel secured AES
implementation for a typical automotive processor. The resulting
implementation is very competitive in terms of program and memory size
as well as performance. The security of the implementation is adapted to
the current security level of automotive processors (low-cost
countermeasures since we have no secure memory or tamper protection).
Therefor i will peresent currently known masking methods and combine
them with randomization to archive a first order DPA resistance.
