Design method of SoC (System on Chip) security disk control chip architecture for trusted storage

Abstract

The invention discloses a design method of an SoC (System on Chip) security disk control chip architecture for trusted storage, and provides the SoC security disk control chip architecture for trustedstorage and a read-write method of the SoC security disk control chip architecture. The credibility of a security disk control chip is insufficient, a traditional trusted computing model is mostly adopted, and the security of information storage is improved from a host side. The invention discloses an SoC security disk control chip architecture for trusted storage. The SoC security disk control chip architecture comprises a central processing unit, an interface controller, a buffer and a trusted module, and the trusted module comprises a parallel hardware encryption engine. And a plurality ofencryption and decryption units are arranged in the parallel hardware encryption engine in parallel. The encryption units and the decryption units are the same in structure, and the multiple split data parts are encrypted or decrypted respectively. Through the multi-engine technology, the multiple encryption engines are used for carrying out parallel encryption processing on the data, the multi-channel control technology is used for partitioning the to-be-encrypted data, each block is subjected to independent encryption processing, and therefore bandwidth expansion is achieved.

Description

technical field [0001] The invention belongs to the technical field of hard disk data reading and writing, and in particular relates to a SoC security disk control chip architecture for trusted storage and a reading and writing method thereof. Background technique [0002] The core component to realize solid-state storage control is a solid-state storage control chip, that is, a disk control chip. There are many foreign manufacturers who have participated in the research of solid-state storage control chips, including Intel (Marvell), Seagate (Sandforce), J-Micron, Samsung, IDT, etc. However, due to the difficulty of disk control chip design technology, many technical bottlenecks cannot be effectively Many manufacturers have gradually given up research in this field and instead purchased mature chips or IP cores for system integration of solid-state storage devices. After several years of elimination, only Intel ( Marvell), Seagate (Sandforce), J-Micro, Samsung Corporation....

AI Technical Summary

Problems solved by technology

[0006] In terms of Soc security disk control chips, there are still some problems in China. The main manifestations are: first, disk control chips are mostly dominated by foreign companies, and domestic companies rarely have independent design capabilities; second, security disk control chips are not reliable enough. The traditional trusted computing model is mostly used to improve the security of information storage from the host side; the third is that the security disk control chip lacks scalability, and the encryption algorithm cannot be dynamically configurable
