A monitoring system identity authentication method for mobile cloud computing

Abstract

The present invention discloses that the present invention relates to the technical field of air-space-earth-sea integrated communication, and specifically relates to a mobile cloud computing monitoring system identity authentication method, which includes the following steps: S1. The location of the fixed camera; S2. The user mobile phone downloads the mobile terminal APP , register and send an authentication request; S3. The cloud selects an elliptic encryption curve, configures the initial private key x and random number u, and calculates the security parameters according to the initial configuration, and returns a request response; S4. The user passes the authentication H 1 (ID i ,r i )Y+G i =s i *P, confirm G i Whether it is sent by the cloud; S5. Cloud computing: m=V u mod n=g uv mod n; m is used here as a fresh value to prevent replay attacks; S6. cloud computing h 2 =H 1 (ID i +G i ), T 2 =z*(T i +G i + h 2 Y+h 1 P); S7. Cloud verification signature H 2 (T 2 +ID i +m)=h 1 Whether it is established, if it is established, continue to verify; S8, cloud computing C 2 -s i C 1 =P M . The invention has the advantages of higher security, lower calculation complexity, no third-party authentication and the like.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to an identity authentication method for a monitoring system of mobile cloud computing. Background technique [0002] With the development of intelligence, in order to provide a higher frame rate, larger pixel high-definition, networked video surveillance system, it needs to be combined with cloud computing and the Internet of Things. According to the different choices of the client, cloud computing is subdivided into two concepts: traditional cloud computing and mobile cloud computing (MCC: Mobile Cloud Computing). The main difference between mobile cloud computing and traditional cloud computing is whether mobile devices are used as the client. With the popularization of smart phones, in the system design, choosing a mobile device as a client is more in line with market demand. From a technical perspective, mobile cloud computing combines mobile computing, cl...

Problems solved by technology

[0004] The existing mobile cloud identity authentication protocol builds a secure identity authentication system based on the trusted cloud. However, the current cloud facilities mostly use the cloud equipment rented from the cloud service provider, which cannot provide reliable security guarantees and has serious security risks.
