Cracking your implanted chips with a cell phone

An article on EETimes.com discusses a way that cellphones could be used to crack RFID chips:

"A well known cryptographer has applied power analysis techniques to crack passwords for the most popular brand of RFID tags.

I haven’t tested all RFID tags, but we did test the biggest brand and it is totally unprotected,” Shamir said. Using this approach, “a cellphone has all the ingredients you need to conduct an attack and compromise all the RFID tags in the vicinity,” he added.

Shamir said the pressure to get tags down to five cents each has forced designers to eliminate any security features"

Do you want the password on your implanted chip to be vunerable to an attack by someone’s cell phone? I thought so.
