Abstract

The invention relates to a PCI password card, and a password operation method and system for massive keys, wherein the PCI password card is characterized by comprising a main control chip module; and the main control chip module encrypts multiple plaintext keys in the PCI password card to generate cipher keys. The storage size of the cipher keys in the invention can be flexibly configured according to an operation system; several hundreds of M, even G bytes, can be supported; requirements of clients on massive keys can be satisfied; the condition that the keys appear in the memory of the operation in the form of plaintexts can be put an end; the safety of keys is ensured; the size of the storage space can be flexibly configured by clients; and thus, requirements of clients on massive keys can be satisfied.

Description

technical field [0001] The invention relates to a PCI cipher card and a massive key cipher operation method and system, belonging to the field of information security. Background technique [0002] China's information industry is developing rapidly, e-commerce and e-government applications are gradually becoming popular, and application platforms such as online banking, online securities, and online shopping are constantly being introduced. Big data and cloud storage are also booming. Not only industry users, but also enterprises and individual users have gradually deepened their understanding of security. Especially in recent years, enterprise-based security application platforms and related products have been widely used. PCI cryptographic card is a cryptographic device with the interface of PCI local bus or PCI Express, which has cryptographic operation function, key management function, physical random number generation function and device's own security protection meas...
