The design and implementation of key server data store based on private cloud localization

摘要

In the era of big data, the requirement for information security and system reliability has become more and more strict. There are some disadvantages in the application of the existing universal data backup and synchronization scheme to the data storage of the key server (The security problems in data transmission and the synchronization problem in the case of the primary is not connected to the secondary). In this paper, according to the traditional multi machine backup technology, a data synchronization scheme is proposed based on the private cloud key server. It effectively solves the problem of data synchronization in the case of the primary and the secondary is not connected. Meanwhile, in the process of data transmission, the method that extends the PKCS#7 international encryption standard is proposed to support domestic encryption algorithm. In this way, it conforms to the State Cryptography Administration standard and improves the security of data transmission.
