Recently I came across an article about "partitioning attack"
http://news.com.com/2100-1040-901920.html
It looks like the author is a little bit far from technical understanding of the technique. He wrote that the technique
"...requires a computer, a SIM card reader and the right program. The program asks the target card seven specific "questions," and it analyzes the signals from the card to determine how it's processing the queries. By analyzing the electromagnetic field changes and power fluctuations, the researchers can divine the card's cryptographic identity" :confused:
This assumes a special device to analyze power fluctuations or a special reader.
Besides mentioning author's mistake in SIM acronym explanation, does anybody have any comments or references to detailed explanation of the hardware?
Thanks
