CP-ABE-based Yellow River dam bank monitoring data sharing method

Abstract

The invention relates to the field of dangerous case monitoring, in particular to a CP-ABE-based Yellow River dam bank monitoring data sharing method. The method comprises the steps that a resource uploader generates an identity number for a resource visitor according to the security level of the resource visitor; the key generation center generates an identity token according to the identity number, calculates an identity verification code and sends the identity verification code to the cloud server; the key generation center generates a private key and sends the private key to the resource visitor, wherein the private key comprises an identity token; the cloud server carries out pre-decryption according to the identity token submitted by the resource visitor, and if the pre-decryption is not successful, the access is stopped; and if the pre-decryption is successful, further verifying the security level of the identity number of the resource visitor and sending the dangerous case resource file ciphertext to the resource visitor for decryption. According to the method, the revocation efficiency is improved while the revocation fine granularity is ensured, the security during resource sharing is also ensured, and the dam bank dangerous case resources are prevented from being maliciously stolen.

Description

technical field [0001] The invention relates to the technical field of monitoring river danger, in particular to a CP-ABE-based method for sharing monitoring data of Yellow River dam banks. Background technique [0002] In recent years, the precipitation in the Yellow River Basin has been relatively high during the flood season, and the possibility of heavy rain and floods in the middle and upper reaches has gradually increased, which has brought great hidden dangers to the personal and property safety of residents along the Yellow River. The situation of flood control in the Yellow River is very severe. In the face of flood conditions, the traditional method of manually inspecting dams is inefficient, and dangerous situations may not be discovered in time. Therefore, if technological means are used to monitor the condition of the dam bank in real time, the monitoring efficiency can be greatly improved. The Yellow River Dam Bank Danger Warning System uses high technology to ...

Problems solved by technology

In the face of flood conditions, the traditional method of manually inspecting dams is inefficient, and dangerous situations may not be discovered in time. Therefore, if technological means are used to monitor the condition of the dam bank in real time, the monitoring efficiency can be greatly improved

The Yellow River Dam Bank Danger Warning System uses high-tech to boost the flood control of the Yellow River. It uses cameras deployed on the dam bank to monitor the dam bank situation in real time. The video resource files captured are stored in the cloud server. If anyone can access the resource files on the network, the resource files may be maliciously stolen, and the security cannot be guaranteed. Therefore, it is of great significance to propose an access control mechanism for resource files in dam-bank dangers.
