AI Technical Summary

Benefits of technology

It describes an improved way to create keys from data transmitted over networks like Control Area Networks (CAN). By sending both bits together simultaneously or one after another, we get multiple copies of them onto their own communication line instead of just adding ones beforehand. These techniques simplify the process while also reducing its costs compared to previous methods such as assigning binary numbers directly into memory devices.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving safety measures during vehicle/industrial network communications without compromising its confidential nature. Current methods rely heavily upon secure protocol standards such as Transport Layer Security Protocol version 4 (TLS-4), which requires both time and computation resources. However, there has also become an issue where certain types of vulnerabilities were discovered through cyberattacks. These weaknesses make them difficult targets for detectors because existing solutions require complex calculations and expensive key generation techniques.

Abstract

The invention belongs to the technical field of computers, and particularly relates to a key generation method and device, a computer readable storage medium and terminal equipment. The method is applied to a first node in a preset controller local area network, the first node is any node in the controller local area network, and the method comprises the following steps: generating a first bit sequence; sending the first bit sequence in a bus of the controller area network; receiving a superimposed bit sequence in a bus of the controller area network, wherein the superposed bit sequence is a bit sequence formed by superposing the first bit sequence and the second bit sequence, the second bit sequence is a bit sequence generated by a second node, the length of the second bit sequence is equal to that of the second bit sequence, and the second bit sequence and the first bit sequence are sent in a bus of the controller local area network at the same time; and generating a key according tothe superposed bit sequence.
