The invention discloses a heterogeneous compiling algorithm feasibility evaluation method and system, and the method comprises the steps: determining the heterogeneity of heterogeneous server software, and determining a performance loss value of the heterogeneous server software; based on the ratio of the performance loss value to the isomerism, calculating and obtaining the isomerism cost-effectratio of the isomerism server software; and obtaining an evaluation result of the feasibility of the heterogeneous compiling algorithm based on the heterogeneous cost-effect ratio. According to the method, the heterogeneity of the server software in the system and the performance loss values of the server software before and after diversified compilation can be quantified, so that the actual benefit generated by each heterogeneous software compilation algorithm can be quantitatively evaluated, and data support is provided for further selecting the heterogeneous server software to establish a web server with a mimicry structure.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to a method and system for evaluating the feasibility of a heterogeneous compilation algorithm. Background technique [0002] As the country pays more and more attention to cyberspace security, more security defense technologies are gradually emerging. As an innovative security defense technology, cyberspace mimicry defense technology adopts the core architecture of "Dynamic Heterogeneous Redundancy" (DHR, Dynamic Heterogeneous Redundancy), which is the premise of ensuring the functional equivalence of each executive body and the high probability of calculation results. In this way, the probability of common mode faults in the system due to design defects (or unwanted redundant functions or "dark functions") is reduced, and the security of the system is further improved. [0003] As a typical engineering implementation of mimic defense technology, web server with mimic str...
