An embedded security encryption chip based on a cloud server

Abstract

The invention discloses an embedded security encryption chip based on a cloud server. The embedded security encryption chip comprises a CPU, an SM2 asymmetric encryption algorithm module, an SM3 hashalgorithm module, an SM4 symmetric encryption algorithm module, an RSA asymmetric encryption algorithm module, an SHA hash algorithm module, an AES symmetric encryption algorithm module, a true randomnumber generator, a physical unclonable function module and a peripheral interface module which are integrated in the system. the embedded security encryption chip is externally integrated with PCI-Einterface, PCI-E interface connects to on-chip bus through PCI bridge, and the security encryption chip is inserted into the cloud server through the PCI-E interface. The digital signature verification and encryption/decryption speed is high, the secret key cannot be cloned, the security is high, the complexity of secret key management can be greatly reduced, the system resource consumption is reduced, the power consumption is reduced, And the chip is inserted into the cloud server through the PCI-E without changing the hardware architecture of the server, and has a secure API, so that a usercan quickly and conveniently call.

Description

technical field [0001] The invention relates to the field of data security encryption, in particular to an embedded security encryption chip based on a cloud server. Background technique [0002] The Internet of Things is a network system that connects people, things, and servers. It is a network that extends and expands on the basis of the Internet. In recent years, with the popularization of smart terminals and the rapid development of information technology and artificial intelligence, smart devices based on Internet of Things technology have gradually entered people's lives, and smart lights and smart speakers can be seen everywhere. In the near future, tens of billions of smart nodes will be connected to the Internet. However, as the Internet of Things is a huge network, the security challenges it faces cannot be underestimated. Security chips with high security, strong real-time performance and low power consumption can play a key role in the field of information se...

Problems solved by technology

[0003] In the traditional data encryption and decryption and digital signature technology, the transmission of files is usually limited by the environment and terminals between the two parties. Users need to have terminal encryption equipment to perform data encryption and decryption and user signatures, and the maintenance cost is high.

In the security services provided by the existing cloud servers in the cloud, encryption, decryption and digital sig
