Wearable computing has been used in a wide range of applications. But wearable computing often suffers from various security and privacy issues. To solve these issues, many effective authentication schemes have been proposed. However, most of the existing schemes are vulnerable to various known attacks (such as desynchronization attack, privileged-insider attack, and anonymity attack), or require high computation and communication costs, and are not suitable for resource-constrained wearable devices, or simultaneous verification of multiple wearable devices is not supported. Therefore, in this...
