The fear of credit cards being hacked and misused is something every individual has experienced. However, a group of researchers of Indian-origin have been successful in putting a rest to this fear. They have developed a new type of radio frequency identification (RFID) that is virtually impossible to hack, thus preventing the credit card number of key card information from being stolen or misused. The RFID chip would run a random-number generator that would spit out a new secret key after each transaction.
As per the inventor, Chiraag Juvekar, a graduate of Massachusetts Institute of Technology (MIT), the chip is devised to prevent so-called side-channel attacks. Side-channel attacks analyze patterns of memory access or fluctuations in power usage when a device is performing a cryptographic operation, in order to extract its cryptographic key.
Speaking on the invention, Chiraag said, “The idea in a side-channel attack is that a given execution of the cryptographic algorithm only leaks a slight amount of information”.
The researchers presented their research at the International Solid-State Circuits Conference held in San Francisco, the US along with the Texas Instruments that has built several prototypes of the new chip.
