Embodiment Construction

[0049] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0050] Example to use bluetooth connection between device and phone:

[0051] To transmit data on a wireless device, a connection must be established first. The way to establish a connection is nothing more than entering a password for verification when establishing for the first time, or opening a connection without verification.

[0052] In this example, if figure 1 As shown, the Bluetooth setting of "Device 1" is set to open connection, and the mobile phone can connect to "Device 1" at any time. In this way, there is no security authentication mechanism at all.

[0053] The way of password acquisition in the method of the present invention is as follows: figure 2 Shown, the flow process of the inventive method is as image 3 Shown:

[0054] A general non-secure connection is established first. It may be a one-time authentication method, that is, authentic...

Abstract

The invention discloses a dynamic security encryption method for Internet of Things. The method is used for establishing an initiative authentication mechanism and dynamic password authentication between wireless transmission devices. A system for implementing the method comprises a connecting device, a password book selecting device, an access code judging device, an authentication end pointer maintaining device, an authentication end pointer increasing device, an authentication judging device, a sending end pointer increasing device, a two-end pointer increasing device, a password pointer judging device, a connection maintaining device, a disconnecting device and an irregular authentication device. According to the method, connection is determined in an initiative password authentication mode, further, instead of use of a calculation result obtained with a single formula, irregular authentication and a two-factor authentication mode of password books and dynamic password pointers are adopted, accordingly, a Trojan horse program is prevented from getting a control right, and system automation can be realized.

Description

technical field [0001] The invention relates to the field of encryption technology, in particular to a dynamic Internet of Things security encryption method. Background technique [0002] There are many devices in the Internet of Things, and the simple embedded single chip is the mainstream. It cannot use point-to-point encrypted transmission for every transmission like a computer. At most, it only authenticates once when establishing a connection. In the past, terminal devices only received the control of a single device, and there was no security problem in the transmission process. After the popularity of the Internet of Things, once these devices are connected to the cloud network, hackers or illegal users can use network Trojan horse programs or other means to gain control of the devices, so that they can control the terminal devices. lead to the destruction of the security of the whole system. [0003] The current encrypted transmission method similar to that of a co...
