Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The present invention introduces a core node library and an active node library, and the core node is a node established to ensure the reliability of the Ethereum POW consensus algorithm and maintain the normal operation of the Ethereum. Different from other nodes, the information of these nodes is co-opened to ensure that the new nodes joining the Ethereum can communicate with the Ethereum network normally. The core node library is used to store the core node information, and the node information recorded by the core node library refers to the IP address information crawled from related web pages.

[0035] The active node database contains the information of the active Ethereum nodes in the current area. The active node database is initially filled by the core node database. As the identification process progresses, the active node database tends to conver...

Abstract

The invention discloses a lightweight Ethereum encrypted traffic identification method. The method comprises the following steps of firstly, setting an active node database to record Ethereum active node information, initializing an active node database by an Ethereum core node database, and dynamically updating the active node database according to a traffic identification result; and then, for nodes recorded in the active node database, identifying whether the nodes are Ethernet UDP traffic or not according to the port number, the message size and the message arrival sequence, encrypting handshake by the Ethernet, and identifying whether the nodes are Ethernet TCP traffic or not according to a message statistical result. According to the method, the characteristics of the encrypted flowof the Ethereum can be fully utilized, the encrypted flow of the Ethereum can be accurately identified, and a solid foundation is laid for network supervision of the Ethereum.

Description

Technical field [0001] The invention belongs to the field of encrypted flow measurement, and particularly relates to a lightweight Ethereum encrypted flow identification method. Background technique [0002] Blockchain is a kind of accounting technology that is maintained by multiple parties and can achieve consistent data storage, non-tampering, multi-party access, and decentralization. It is also called distributed ledger technology. Blockchain provides new solutions for further solving the trust issues, security issues and efficiency issues in the Internet, and also brings new opportunities and challenges to the development of finance and other industries. In recent years, the application of blockchain technology has become widespread, but the regulatory issues that follow have become more prominent. The anonymity of the blockchain and the multi-party maintenance design make the effective supervision of the blockchain very difficult. [0003] As a representative application in...
