基于OTA技术的A-Key算法及其数据生成

A-Key algorithm and the generation of its data based on OTA technology

在OTA鉴权中,A-Key的修改必须以保密的方式进行.利用基于D-H的A-Key算法,进行A-Key数据生成管理研究.研究得到的方法能够以保密的方式对A-Key数据进行修改,安全性高和可靠性强,为OTA技术提供一种具有安全保证的A-Key数据管理方法.

The amending of A-Key must be processed cryptically in OTA authentication. So this paper deals with the algorithm of A-Key based on D-H and then discusses the generation and management of the data of A-Key using the algorithm above. The method discussed can amend the data of A-Key secretly and is advantageous in security and reliability compared with other algorithms. It can also provide a secure method for managing the data of A-Key for OTA technology.
