MIT computer experts unveil RFID chip technology that is 'impossible to hack'

MIT computer experts unveil RFID chip technology that is 'impossible to hack' | Sciences & Technology | Scoop.it

Cutting-edge research from Massachusetts Institute of Technology makes bold claims about RFID technology.

 

"A team of computer experts from the Massachusetts Institute of Technology (MIT) has reportedly constructed a tech-savvy type of Radio Frequency Identification (RFID) chip that is impossible to hack. Alongside researchers from Texas Instruments, the group has already built and tested a number of prototypes that back up their assertions.

RFID chips are now commonplace, used in everything from passports and transport swipe cards to amusement-park tickets. However, as security and privacy concerns among the public have grown in recent years, and with people becoming increasingly suspicious of the technology, the MIT research could be welcome news to those that rely on such chips.

Cutting-edge research from Massachusetts Institute of Technology makes bold claims about RFID technology.


Now, the researchers claim their cutting-edge findings would mean that security concerns regarding RFID systems become a thing of the past. According to Chiraag Juvekar, an electrical engineering graduate at MIT and a co-author of the research, the new chip has been designed to curb so-called 'side-channel attacks' that can be used to steal the encryption keys contained in RFID technology.
