Product: OTA Solution that supports one-vehicle, one-key upgrade package encryption and decryption

Description

Encrypt each vehicle with a different key by extracting a small portion of the data from the upgrade package file. For most of the remaining data, all cars are encrypted with the same key as before. In this way, for each vehicle, the encrypted upgrade package is still different, which better solves the problems existing in the current solution.

Unique advantages

By upgrading the file segmentation processing, the high-security requirement of one-vehicle, one-key is met, and the storage pressure on the server-side is reduced at the same time.

Application

OTA has become one of the most important symbols of the current smart car, and the upgrade scope gradually covers the functions of all parts of the car. Therefore, OTA upgrades will become the norm. The industry also attaches great importance to the safety of automotive FOTA functions.

Prospect

With the advent of the era of automobile intelligence, the emphasis on OTA security will be greatly increased. At present, the conventional solutions in the industry still have defects: vehicles with the same upgrade package have the same encryption key, so as long as one vehicle is cracked, other vehicles will also be seriously threatened. Desay SV's OTA solution can solve this problem very well.
