Cipher Based Data Security Sharing Scheme

Enterprises need to collect and store a large amount of business data in various business systems, which may include sensitive data. If traditional data encryption schemes are used to encrypt and store important data, it may lead to the problem of “data silos” between different entities and systems. If the data is plaintext and directly forms complex and real-time interaction and circulation links between different entities, it may lead to problems such as data abuse and data leakage. This article proposes a password based data security sharing scheme, which solves the security problem of data circulation in actual business processes through SM2 and SM4 algorithms.
