Encryption algorithm identification method based on deep learning graph network

Abstract

An encryption algorithm identification method based on a deep learning graph network is composed of a training process and an inspection process, and comprises the following steps: training: constructing a basic source code library for crawled source code data related to encryption; carrying out cross-compiled preprocessing, obtaining a binary code library, respectively extracting statistical characteristics and structural characteristics of a binary encryption algorithm, integrating the statistical characteristics and the structural characteristics to generate an encryption algorithm graph, embedding the encryption algorithm graph into a neural network to become vectors, judging whether codes are similar or not by comparing distances among the vectors, and obtaining a model for judging whether embedded vectors of the encryption algorithm graph are similar or not through training; checking: generating a standard encryption algorithm library, selecting one copy of encryption algorithm which is standardized and has been determined in type; generating an encryption algorithm graph, generating an encryption algorithm graph for the to-be-detected encryption algorithms of unknown types,embedding the encryption algorithm graph into the trained model, sequentially comparing the vector distances with the embedding of the standard encryption algorithm library, and taking the standard algorithm type with the shortest vector distance to the to-be-detected encryption algorithms as the type of the to-be-detected encryption algorithms.

Description

technical field [0001] The invention belongs to the field of computer software security, relates to algorithm encryption and identification, and in particular to an encryption algorithm identification method based on a deep learning graph network. Background technique [0002] 1.1 Related technical background [0003] Information security has now risen to the strategic position of national security. As the core of data transmission security, encryption algorithm is widely used in politics, finance, communication and other aspects. With the development of LoT technology, embedded systems are increasingly used in various loT devices, and their security is also one of the focuses of current information security research. For a long time, in industries with high security requirements such as financial enterprises and government agencies, in addition to using internationally accepted cryptographic algorithm systems and standards such as 3DES, SHA-1, and RSA, there is also a set ...
