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...

Embodiment Construction

[0055] Such as Figure 1-4 As shown, a mobile cloud computing monitoring system identity authentication method, using the elliptic curve algorithm to design the authentication method, encrypts the user, the authentication method is used as a signature algorithm, and uses the Diffie–Hellman protocol to encrypt a random parameter at the same time, As a fresh value, it prevents replay attacks; the entities involved in this scheme are the cloud, mobile users, and cameras.

[0056] The Diffie-Hellman algorithm is a public key key exchange algorithm based on the difficulty of solving discrete logarithms, which can securely exchange encrypted keys on an insecure channel. Before this method appeared, both communicating parties needed to share the key through a secure channel, or a third party distributed the key, but now the commonly used channels are untrustworthy in the eyes of users, and the introduction of a trusted third party also needs to increase the communication cost. The D...
