IBM scientists have developed a new mobile authentication security technology based on a radio standard. It’s known as near-field communication or NFC and enables so- called two-factor authentication to secure mobile transactions, such as accessing an Intranet or private cloud. Two-factor authentication is already common when using a computer. Think password and verification code. IBM scientists now say they can apply the same concept using a personal identification number and a contactless smartcard like an employer-issued identity badge. The IBM technology is based on end-to-end encryption between the smartcard and the server using the National Institute of Standards and Technology’s Advanced Encryption Standard scheme.
