A server of the present application issues a service key for using a specified vehicle and a plurality of one-time authentication keys on the basis of a request from a mobile terminal, and distributes the same to the mobile terminal. The one-time authentication key is a one-time authentication key generated on the basis of the service key, and has a set valid period. The one-time authentication key is consumed when the vehicle device authenticates the mobile terminal to be communicated. And the mobile terminal replaces the self-kept one-time authentication key at any time.
本申请的服务器基于来自移动终端的请求,发放用于使用指定的车辆的服务密钥、和多个一次性认证密钥,并分发至移动终端。一次性认证密钥是基于服务密钥生成的一次性的认证密钥,设定有有效期限。一次性认证密钥在车辆用装置认证作为通信对象的移动终端时被消耗。移动终端随时更换自身保持的一次性认证密钥。
