I've previously mentioned Flylogic as a company that does cool attacks on chip-level hardware protection. In http://www.flylogic.net/blog/?p=18 , they talk about attacking the ST16601 Smartcard - described by the vendor as offering "Very high security features including EEPROM flash erase (bulk-erase)". The chip is covered by a metal mesh that, if cut or shorted, blocks operation. However, Flylogic reports: "Using our techniques we call, b magicb (okay, itbs not magic but webre not telling), we opened the bus and probed it keeping the chip alive. We didnbt use any kind of expensive SEM or FIB. The equipment used was available back in the 90bs to the average hacker! We didnbt even need a university lab. Everything we used was commonly available for under $100.00 USD. This is pretty scary when you think that they are certifying these devices under all kinds of certifications around the world." -- Jerry --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo@metzdowd.com ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
