Abstract

The invention provides a network tax control encryption server based on an ARM11 platform. The CUP (Central Processing Unit) of the encryption server adopts the processor of an embedded ARM11 platform and an operating system adopts LINUX. In order to ensure the reliability of the encryption server, key parts all adopt a double-copy form; double powers ensure the reliable power supply of the encryption server; double network cards ensure the stable communication of a network; double SD cards ensure the safe storage and the transportation of data such as electronic stubs and the like; and an encryption chip is directly mounted on the bus of the CPU. Compared with the conventional PCI encryption card form, the server ensures the reliable generation of encrypted data, and a mainboard can expand the quantity of the encryption chips to meet the requirements on different users.

Description

technical field [0001] The invention relates to the technical field of financial tax control, in particular to a network tax control encrypted server based on ARM11 platform, which relates to embedded intelligent control technology. Background technique [0002] Taxpayers in chain-operated industries represented by the post and telecommunications industry urgently need a solution to reduce invoices, so as to reduce taxpayer operating costs and save social resources. Based on the above status quo, we propose an invoice electronic stub solution with the network tax control encrypted server as the core. At present, most of the network tax control encryption servers on the market adopt the solution of industrial computer integrated with PCI encryption card. This solution has compatibility problems between the main board of the industrial computer and the encryption card, and has poor scalability, high energy consumption, and high cost. For this reason, this patent proposes a ne...
