Validating and Securing Spontaneous Associations between Wireless Devices

摘要: One of the sought-after characteristics mobile and ubiquitous computing environments is for devices to become spontaneously associated interoperate over wireless networks. However, unlike cable that connects two in a wired association, network does not provide physical indication which device on other end association. Further, messages sent are readily accessible same network. Hence, spontaneous association subject various spoofing replay attacks. We introduce protocols thwart these attacks by physically validating and, so doing, exchanging shared session key between them subsequent secure communication.
