Abstract

The invention discloses an access control method based on an attribute-based access control policy. The method is characterized by 1) extracting attribute information of a user-role table and a role-authority table in a database and generating a user-role-authority access control relation Hash table; 2) generating an access control policy according to the access control relation Hash table: carrying out iteration traversal on the access control relation Hash table to obtain key value pairs, that is, an attribute set of each user and authority thereof, and then, generating an access control policy rule of the user according to the authority attribute of the user; and 3) for each received access request, an internet-of-thing search engine judging the access request according to the access control policy rule to determine whether access is allowed. The method can give a quick response to the search request, thereby greatly improving efficiency of the internet-of-thing search engine.

Description

technical field

[0001] The invention belongs to the field of network technology, and in particular relates to an access control method based on an attribute access control policy. Background technique

[0002] The background of the present invention is that in the Internet of Things search environment, when a user searches for third-party data, in order to protect the privacy of the user, the Internet of Things search engine cannot tell the third-party user information, so the third-party database data and its role-based access control The policy is submitted to the Internet of Things search engine, and the Internet of Things search engine judges the user's access rights to resources and returns a response to the user. There are various third-party access controls. However, the access control commonly used in the Internet of Things is attribute-based access control. If the third party can convert the access control strategy and data to the Internet of Things search engine be...
