Tel Aviv University has developed a new method to steal data from computers. Using a simple electrical trick is enough for sophisticated hackers to gain access to thousands of encrypted keys. Access to encrypted keys could be used to make hundreds of digital signatures used all the time by people when creating passwords, signing contracts, or perhaps most importantly, using credit and debit cards online. The team will present their research in a talk titled, at Workshop on Cryptographic Hardware and Embedded Systems 2014 (CHES 2014) in Korea, on September 23th.
