Baidu successfully cracked the T-BOX system car network security to a new height

Today, the development of driverless and car networking has attracted worldwide attention, and the safety issues after the application of driverless and assisted driving systems have surfaced. The diversification of vehicle networking applications, the networking and intelligence of future automotive in-vehicle systems have increased the way of intrusion, and hackers can even crack the in-vehicle control system without any physical contact.

Baidu successfully cracked the T-BOX system car network security to a new height
Previously, the car networking systems of many well-known car companies were successfully cracked by hackers, seriously threatening the personal safety of drivers and passengers. In 2015, a hacker successfully invaded the Cherokee Jeep's "Uconnect" system, remotely controlled the car's acceleration and braking systems, radios and wipers and other equipment; in 2016, Tesla was also exploding software vulnerabilities, Tencent's security team passed The vulnerability launched a remote attack on the ModelS car without physical contact and gained control of the vehicle. According to industry forecasts, by 2018, the Chinese car networking market will reach 200 billion yuan. The hidden dangers behind the rapid development of the Internet of Vehicles have also caused great concern in the industry.
The Chinese Academy of Engineering academician He Hezhen said that the Internet of Vehicles will be one of the biggest drivers of the Internet of Things. The Internet of Things is redefining the car. A good car will have hundreds of intelligent hardware devices. Therefore, for network security researchers, the security design from switching from Internet security research to focusing on smart hardware devices, sensors and ECUs in the Internet of Vehicles has become a trend.

As one of the pioneers of domestic unmanned vehicles, Baidu has always placed safety first, and the safety of the Internet of Vehicles is a top priority. Unlike traditional Internet security ideas such as software vulnerabilities, website vulnerabilities, and wireless attacks, the Cloud Security Lab under the Baidu Autopilot Division conducted a security analysis of the T-BOX, the core control system for the Internet of Vehicles, through a more comprehensive technology. Successfully cracked, realizing local control of the vehicle and remote control of other vehicles. This will further enhance the safety of the car network and escort its wide application.

According to reports, the T-BOX system is integrated with GPS, RFID (radio frequency technology) identification, sensors, cameras and image processing electronic components, in accordance with communication protocols and data interaction standards, wireless communication and information exchange The system network is also the basic network for intelligent traffic management, intelligent dynamic information services and intelligent vehicle control. The safety factor of the T-BOX network determines the safety of the car and the entire intelligent transportation network, and is one of the core technologies for the development of the car network.

In order to crack T-BOX, Baidu Security researchers completely analyzed the hardware structure of T-BOX, debugging pins, WIFI system, serial communication, MCU firmware, code reversal, CAN bus data, T-BOX fingerprint features and other research points. Successfully broke the hardware and software security system of this T-BOX, hijacked the serial port protocol data between ARM and MCU, realized the tampering of the protocol transmission data, so that the user's command can be modified or the forged command can be sent to the CAN controller. , to achieve local control and remote operation control of the vehicle.

In addition, by cracking the Wi-Fi and mobile communication networks entering the T-BOX, combined with the research on the physical fingerprint feature extraction of the T-BOX device, Baidu security researchers searched the T-BOX of other vehicles and successfully searched for another one. The test car and the remote landing, gained control of the car. This means that the Baidu security team has simulated remote threats to the in-vehicle system that may emerge in the future, so that the R&D personnel of the in-vehicle system can plug the relevant vulnerabilities before the system is launched, and prevent similar attack paths that may occur, and ensure the in-vehicle system. Strict, complete and safe.

The successful cracking of the T-BOX system by Baidu marks that the industry's research on the safety of the car network has risen to a new height, and it has important guidance and forward-looking value for the future development of the car network security technology. In the future, Baidu will work closely with car companies to improve the safety line of the car networking system and ensure the safe and smooth operation of intelligent assisted driving and unmanned driving in the future.

33kV Dry Type Transformer

We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for33kV cast resin Dry Type Transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
