| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | OAuth is one of the protocols that enable to authorize resource access for a client through API. The authorization by OAuth is accomplished by issuing access token to the client with approval from the user. By using access token, the client can share the user’s information between applications without exchanging the authentication information of the user. In OAuth, it is assumed that access token would be stored on high security platforms such as smartphones and computers. On the other hand, however, it has been hardly considered about how to deal with access token on the platform with limited resources like IoT devices. Therefore, its implementation is client-dependent and could be vulnerable against the threat that access tokens could be stolen by the device analysis. In this paper, we made a consideration about using OAuth in combination with Physically Unclonable Function (PUF) as the authorization protocol for IoT devices. The client can share the secret information like access token with an authorization server without holding the information while minimizing the operation cost of the server in this protocol. The protocol enables to accomplish secure authorization against the threats that the secret information could be stolen from the clients. |
