Embodiment Construction

[0009] specific implementation plan

[0010] An embedded encryption system including server and client.

[0011] The most important mechanisms in the embedded encryption system of the present invention are multi-level key mechanism, security certificate, digital signature, etc., which will be introduced in detail below.

[0012] The main process of the encryption system is: the server side establishes a connection with the client side by generating a security certificate loaded with a specific digital signature, and establishes an encrypted communication connection for communication after a series of information exchanges between the two parties.

[0013] When an encrypted communication connection needs to be established, the client first sends a connection establishment request. The server sends a response after receiving the request. After receiving the response, the client first needs to confirm that it is communicating with the correct server, and then establish an encry...

Abstract

The invention provides an embedded encryption system, which is characterized in that the whole system is divided into a server and a client. The server provides a safety certificate containing a specific digital signature; the client identifies the server end through identifying the certificate; and two parties establish an encrypted communication connection after exchanging a series of information. Encrypted communication can be realized through a specific encryption mode under a condition that resource of the embedded system is restricted, thereby ensuring that safety of the embedded system in intercommunication, networking communication and other interactive works. Furthermore, the embedded system can not be crashed in case of failed electronic equipment, hacker attack and the like.

Description

technical field [0001] The invention is an embedded encryption system for establishing encrypted communication. Background technique [0002] From industrial equipment to household equipment, the application of various embedded devices and systems has increasingly penetrated into all aspects of human life. [0003] Therefore, the security problem has increasingly become an important issue that threatens the development of embedded systems. As embedded devices become more and more intelligent, and systems are networked, downloaded, and upgraded more and more frequently, how to ensure the security of network communications has become a key issue for whether the system can work stably. For embedded applications such as smart buildings, ATMs, remote surgery, etc., in addition to ensuring the security under normal working conditions, the security under unexpected conditions such as electronic equipment errors and hacker attacks must also be carefully considered. However, due to...
