Embodiment Construction

[0041] In the following detailed description, numerous specific details of the disclosure are set forth by way of example in order to provide a thorough understanding of the relevant disclosure. It will be apparent, however, to one of ordinary skill in the art that the present disclosure may be practiced without these details. It should be understood that the terms "system", "device", "unit" and / or "module" used in the present disclosure are used as a means of distinguishing between different parts, elements, sections or assemblies at different levels in a sequential arrangement. method. However, these terms may be replaced by other expressions if other expressions can achieve the same purpose.

[0042] It will be understood that when a device, unit or module is referred to as being "on," "connected to" or "coupled to" another device, unit or module, it can be directly on the other device, unit or module. connected or coupled to or communicate with other devices, units or mo...

Abstract

The embodiment of the invention discloses an embedded intrusion detection method and device for a smart contract. The method comprises the steps of testing and analyzing an intelligent contract needing to be protected by using a test case in a test environment, and generating a control flow graph corresponding to the intelligent contract; processing the control flow graph, and marking path features of all test cases to form a safe path feature set; adding the coded security path feature set into the smart contract to form a smart contract with an embedded IDS function, and deploying the smartcontract into a blockchain; and when a notification that the embedded IDS judges that an intrusion behavior occurs is received, marking an exception, and carrying out alarming and rollback.

Description

technical field [0001] The present disclosure relates to the technical field of block chain, and in particular to an embedded intrusion detection method, device, electronic equipment and storage medium of a smart contract. Background technique [0002] Blockchain technology is a distributed data storage technology that is decentralized, does not require third-party authentication, and has peer-to-peer interaction. By maintaining chain-structured data blocks, blockchain can maintain continuously growing and tamper-proof data records. At present, the application of blockchain is mainly concentrated in digital currency, network transactions, etc., but this is only because these fields rely more on certain characteristics of blockchain. In fact, the actual application direction of blockchain is far more than the above-mentioned fields. [0003] The first generation of blockchain is essentially a decentralized data record (such as Bitcoin's ledger) tool, through consensus algorit...
