Embodiment Construction

[0096] The present invention relates to a system and method for generating a private key for a device participating in an identity-based self-certified signature scheme, wherein the device uses the private key to create a public session key for encoding digital communication between devices. Specifically, the private key generated according to the system and method of the present invention is only known to the device itself, and not to any other third parties.

[0097] In addition, before calculating the public session key, the entity pair or device pair will first verify the authenticity of each entity or device. Once each entity is authenticated, the entity pair will then generate a public session key, which is used to encode digital communications between entities.

[0098] figure 1 It shows a block diagram of an entity pair authentication and public session key generation system according to an embodiment of the present invention. Those skilled in the art will recognize that ...

Abstract

This document describes a system and method for generating private keys for devices participating in a self-certified identity based encryption scheme whereby the private key is used by the devices to establish a common session key for encoding digital communications between devices.

Description

Technical field [0001] The present invention relates to a system and method for generating a private key for a device participating in an identity-based self-certified signature scheme, wherein the device uses the private key to create a public session key for encoding digital communication between devices. Specifically, the private key generated according to the system and method of the present invention is only known to the device itself, and not to any other third parties. Background technique [0002] Due to the convergence of multiple technologies, more and more devices can wirelessly communicate with the Internet seamlessly or wirelessly exchange communications between devices. This kind of aggregation makes the prospect of the Internet of Things (IoT) more and more important in recent years. In the Internet of Things, millions of entities or devices (ie objects) will be connected to each other. These devices include devices or entities such as smart chips, smart plugs, s...
