Abstract
With the development of digitalization and Internet technology, enterprise information security is facing more and more challenges. Many enterprises have begun to adopt big data (BD) and artificial intelligence (AI) technology for risk assessment (RA) and prediction to effectively manage information security risks. This article discusses the application of BD and AI technology in enterprise information security management (ISM) and RA from two aspects. Firstly, the mobile payment signature scheme based on number theory research unit is used to improve the security of the mobile payment system. This scheme uses lattice algorithms to achieve fast key generation, signing, and verification and can resist traditional cryptographic attacks. Secondly, a set of enterprise ISM and RA system is established, including risk identification, RA, monitoring and early warning, emergency response, and other links. BD and AI technology is used to analyze internal and external data to provide accurate RA results to achieve automated RA.
