摘要：Recently, CCTV has been advancing with the development of IoT technology and intelligence converging with CCTV, as opposed to recording only videos as in the past. Currently, it is used in various fields. Therefore, there are various security threats in the advanced CCTV environment. For example the attacker can acquire the information of the user captured on the CCTV by acquiring the transmitted video data. Also it is possible to disturb the integrity of the video data by leaking or manipulating it to the outside. Additionally, if an attacker hacks a server that manages multiple CCTV videos, many CCTVs can be affected by the attacker's actions. In this paper, to solve the security threat CCTV, video data is encrypted and managed on the server using the CP-ABE method of attribute-based encryption so that only authorized users can access the video data. In addition, if a person with different attributes wants to access the video data, the video data can be accessed safely by re-encrypting the video data using proxy re-encryption techniques based on the attributes of the accessor.
