摘      要：Wearable devices usually work together with smart *** ensure only legitimate smart phones can read the data,they must conduct pairing to establish a shared *** pairing methods require that the pairing devices have a keyboard or screen for user ***,due to the size limitation,keyboards or screens are hard to be installed in the wearable *** solve this problem,we propose a novel pairing method by using ambient sound and *** this new scheme,any pairing request from smart phone will trigger wearable device *** after users press the confirm key on the device can the pairing process *** pairing devices collect ambient sound and light at the predetermined time and establish a shared key by using the Diffie-Hellman *** protect against potential man-in-the-middle attacks in the key establishment process,an improved interlock protocol with sound and light comparison is conducted to authenticate the *** both the sound and light collected by the pairing devices are similar enough,the key is ***,it is *** with current context based pairing methods,our scheme does not impose strict synchronization on devices to collect ambient context ***,our scheme need not collect and exchange contextual information for multiple times to resist offline brute force *** experimental results and security analysis prove the effectiveness of our scheme.
