Method and system for resource allocation of smart city based on redundancy control strategy Technical Field The present invention relates to the field of information processing technology, and more particularly, to a method and system for resource allocation in a smart city based on a redundancy control policy, a computer-readable storage medium, and an electronic device. Background Since the advent of smart cities, smart cities are valued around the world, and more convenient conditions are provided for people's life while the level of urban intelligence is improved, but because smart cities highly depend on novel technical means such as cloud computing and the Internet of things, hidden dangers of information risk diffusion are brought to technical application, multi-angle impact is brought to urban information safety, and how to reasonably allocate digital resources of the current cities is avoided as much as possible, so that the smart cities become an actual problem that the healthy development of the current smart cities must face. Smart cities are an open, shared, ecologically circulated system, and there are various communications and decisions between cities in terms of information security. There are alternative external resources between smart cities, that is, no matter which city is illegally invaded, no other cities are lost, so that effective improvement is needed when the cities are subjected to resource allocation analysis. Disclosure of Invention According to the application, firstly, problem description and modeling are carried out according to the characteristics of substitutable external resources, then, the information security resource allocation methods under the two conditions of independent strategies and combined strategies are discussed, the influence of factors such as the scale of a smart city or a network system, the invasion probability of illegal users, the substitution rate of the smart city or the network system and the like on the two conditions is analyzed, nash equilibrium solutions under the two conditions are compared, and then, the configuration optimization is carried out according to the actual conditions, and meanwhile, the combined strategies are carried out between the smart city or the network system by introducing a cooperative mechanism. According to an aspect of the present invention, there is provided a method of resource allocation for a smart city based on a redundancy control policy, the method comprising: Determining a plurality of smart cities with alternative external resources, wherein the alternative external resources refer to at least two smart cities storing the same part or all of data resources in the plurality of smart cities, and when part or all of the data resources in a first smart city are maliciously tampered or maliciously deleted, the second smart city can determine whether to utilize the same part or all of the data resources stored in the second smart city as the first smart city to restore the data resources in the first smart city by replacing the data resources; Determining the configuration limit x j of the information security resource of each smart city and the recoverable loss E of the unit information security resource; Based on the configuration limit x j of the information security resource of each smart city and the loss E which can be recovered by the unit information security resource, determining the invasion probability p j of successful invasion of each smart city by illegal users after information security resource configuration: Wherein j is a natural number and 2≤j≤n, wherein n is the number of smart cities with alternative external resources, β is the probability of an illegal user invading the smart cities, wherein the probability of an illegal user invading each smart city is the same, v is the probability of a smart city being successfully invaded by an illegal user without information security resource allocation, wherein v of each smart city is the same, and A redundancy control policy between a plurality of smart cities having alternative external resources is determined, and an amount of resource allocation when each smart city performs resource allocation is determined based on the redundancy control policy and the intrusion probability. Preferably, the method further includes determining, based on the intrusion probability P j that each smart city is successfully intruded by the illegal user after the information security resource allocation, a probability P B that the illegal user attacks the current smart city and successfully intrudes the current smart city in case that the attack of each smart city other than the current smart city fails: wherein p 1 is the probability that an illegal user successfully invades the current smart city B, Representing the probability that an illegal user fails to attack every smart city except the current smart city, and turns to attack the current smart city B.
