Information security management method and system for internet of things based on combinatorial encryption algorithm

Abstract

The invention belongs to the technical field of information security, in particular to an information security management method for the Internet of Things based on a combined encryption algorithm, the invention also provides an information security management system of the internet of things based on a combined encryption algorithm; the cryptographic matrix encryption method comprises the following steps: if the first element M1 and the second element M2 are in the same row, the corresponding first element O1 and the second element O2 are letters adjacent to the right of the first element M1and the second element M2, respectively.As that exist encryption method is relatively simple, when the password is attacked by force, the encryption key can be decrypted quickly by exhausting the limited number of times directly, which leads to the problem of poor information security. The invention has the advantages of enhancing the information security intensity, facilitating the memory and easy storage, ensuring the integrity of ciphertext, and ensuring the flexibility of encryption.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an information security management method for the Internet of Things based on a combined encryption algorithm. The invention also provides an information security management system for the Internet of Things based on a combined encryption algorithm. Background technique [0002] According to the needs of the development of informatization construction, information includes three levels of content: one is the objects collected, transmitted, processed and stored in the network and system, such as technical documents, storage media, various information, etc.; The third is information such as keys and passwords for security management methods. The security management of software facilities mainly considers configuration management, use and maintenance management, development management, and virus management. Software facilities mainly include operating system...

Problems solved by technology

[0003] The present invention provides an Internet of Things information security management method and system system based on a combined encryption algorithm to solve the problems in the prior art proposed in the above-mentioned background technology. Because the existing encryption method is relatively simple, when encountering a brute force attack password, directly Exhaustive enumeration of the limited number of keys can be decrypted faster, which leads to the problem of poor information security
