Password device based on embedded operating system

Abstract

The invention provides a password device based on an embedded operating system. The password device comprises: an administrator key device used for storing a key password; and a host device, wherein the host device is used for communicating with the administrator key device, verifying the key password when scheduling the key for the first time to verify the administrator identity, binding the key password after the verification is successful, carrying out digital signature on transaction data, sending the transaction data to an enterprise ERP system through an enterprise internet after receiving a verification success message, and releasing the transaction data to each enterprise user by the enterprise ERP system to complete a payment transaction operation. The password device provided by the invention has the advantages of high security, multi-core computation, high concurrency, high performance, high stability, high operation processing efficiency and large storage capacity.

Description

technical field [0001] The invention relates to the technical field of the Internet and intelligent terminals, in particular to a cryptographic device based on an embedded operating system. Background technique [0002] With the national emphasis on information security and the improvement of requirements, the scope of cryptographic applications is becoming wider and wider, and the user group is constantly enriched and expanded. More and more small and medium-sized enterprises and institutions need suitable service cryptographic equipment. Different from traditional large-scale enterprise industry users, these users have higher performance requirements than personal devices such as smart password keys, and lower than high-end equipment such as server cipher machines and signature verification servers, and have relatively low cost control. Such customers include small and medium-sized enterprises that use electronic financial services, such as: e-commerce companies, large-sca...

AI Technical Summary

Problems solved by technology

[0013] USBKey has relatively low computing power and only supports single thread. It will encounter a bottleneck in a high-concurrency operating environment. In a multi-concurrency product, it can only be processed in a linear manner. Repeated work will easily lead to errors.
