Practical Electromagnetic Template Attack on HMAC
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. Aft...

An Efficient Method for Random Delay Generation in Embedded Software
Random delays are a countermeasure against a range of side channel and fault attacks that is often implemented in embedded software. We propose a new method for generation of rando...

KATAN and KTANTAN - A Family of Small and Efficient Hardware-Oriented Block Ciphers
Abstract. In this paper we propose a new family of very efficient hardware oriented block ciphers. The family contains six block ciphers divided into two flavors. All block ciphers...

Faster and Timing-Attack Resistant AES-GCM
We present a bitsliced implementation of AES encryption in counter mode for 64-bit Intel processors. Running at 7.59 cycles/byte on a Core 2, it is up to 25% faster than previous i...

Fault Attacks on RSA Signatures with Partially Unknown Messages
Fault attacks exploit hardware malfunctions to recover secrets from embedded electronic devices. In the late 90's, Boneh, DeMillo and Lipton [6] introduced fault-based attacks...

The Frequency Injection Attack on Ring-Oscillator-Based True Random Number Generators
We have devised a frequency injection attack which is able to destroy the source of entropy in ring-oscillator-based true random number generators (TRNGs). A TRNG will lock to freq...

On Tamper-Resistance from a Theoretical Viewpoint
Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defea...
