TL;DR: In this paper, the authors proposed several improvements on Kocher's ideas, leading to a practical implementation that is able to break a 512-bit key in few hours, provided they are able to collect 300000 timing measurements (128-bit keys can be recovered in few seconds using a personal computer and less than 10000 samples).

TL;DR: This paper provides implementations of 12 block ciphers on an ATMEL AVR ATtiny45 8-bit microcontroller, and makes the corresponding source code available on a web page, and evaluates performance figures of the implementations with respect to different metrics, including energy-consumption measurements and shows improvements compared to existing implementations.
A tutorial on physical security and side-channel attacks
TL;DR: This paper aims at providing a tutorial on the physical constraints that a real-life cryptographic device must face, overviewing the main kinds of attacks and highlighting their underlying principles.
