Embodiment Construction

[0052] The present invention will be further described below in conjunction with accompanying drawing:

[0053] see Figure 1 to Figure 5 :

[0054]A Markov process-based cloud computing safety state evaluation model for drug testing, which determines the offset probability that can obtain the corresponding safety and efficiency, constructs a transition state process, and obtains the last two evaluation state strategies through the evaluation of the system and users. Success, If the strategy fails, build the corresponding Markov state diagram;

[0055] x 0 is the initial state, X 1 , X 2 , X 3 ...X i for X 0 A state that may be transferred after passing the efficiency and safety rules;

[0056] P 01 , P 02 , P 03 ......P 0i for X 0 to x 1 , X 2 , X 3 ...X i The probability of X i+1 , X i+2 are the two states obtained after the final system evaluation and user evaluation, representing the successful strategy and the failed strategy respectively;

Abstract

The invention discloses a Markov process-based drug test cloud computing security state evaluation method, and provides an efficient and safe access state strategy which adopts efficient multi-user access, safe different permission guarantee, high resource utilization rate, reliable third-party storage, extendable new algorithm and the like as key points. According to the strategy, four state security libraries are built for different types of classification of users according to behaviors, a user can select an appropriate security access state strategy according to individual needs and drug test cloud computing security and efficiency quantization as well as evaluation rules, and a result obtained by utilizing a Markov chain state transition matrix and using efficiency security and user evaluation as probability coefficients of the transition matrix through transformation calculation is used for evaluating the benefits of the security strategy selected by the user. Through the adoption of the method, resources are saved during drug test cloud computing, the safety is improved, and an appropriate, reasonable and more user-friendly choice is provided for the user.

Description

technical field [0001] The invention belongs to the field of cloud computing, and in particular relates to a Markov process-based drug testing cloud computing security state evaluation method. Background technique [0002] Security and efficiency have always been a pair of contradictions. Security means spending more on authentication, encryption, decryption, etc., while efficiency, on the contrary, makes these processes easier. Therefore, cloud computing in the drug testing industry should also ensure its efficiency while enhancing security, and achieve a balance between security and efficiency. In addition, users of cloud computing in the drug testing industry will also be diverse. There may be administrators, system developers, third parties, the general public, drug testing staff, provincial bureau staff, etc., so that the safety of users Needs, access rights and required services may vary, so security levels cannot be generalized. Due to the above problems, research o...
