Jinbo Electronics and SC6235 chip debuted in Anbang, won the 2018 China International Social Public Safety Product Expo, the first prize of the SCT Safety Product Expo Level test report.
SC6235 is the industry's first ultra low power SVAC2.0 artificial smart chip video encoding chip design with ASIC (full-custom hardware) method. Compared to the DSP soft coding architecture, the ASIC architecture is more advantageous in low power, high compression ratio. The advent of the ASIC architecture encoding chip has successfully encoded the SVAC2.0 encoding power to 0.5 watts. The chip has built-in DDR, which has an advantage of easy integration, high coding efficiency, ultra-low power consumption.
SC6235 fusion compression and intelligent analysis are integrated, not only support SVAC2.0 encoding, but also integrate independently developed convolutional neural network hardware acceleration engines, can simultaneously perform video compression and intelligent analysis, producing high compression than video streams. The SC6235 matching the country's defective chip meets the requirements of data signature and encryption of C-class front equipment for GB35114 national mandatory standards.
The SC6235 uses a self-patented coprocessor architecture for video coding compression, with Haisi IPC master chip in the webcam product. The coordinator architecture greatly reduces the equipment manufacturer transplant operating system, application software, and adjusts the quality of image quality, and customers can quickly launch the GB35114 C-class webcam in accordance with SVAC2.0 standards.
The specifications are as follows:
1. Support 1920x1080p @ 30fps svac2.0 encoding
2. Support depth learning algorithm acceleration, hardware supports Convolution, Pooling, Relu, Concateation, ElementWise and other operations
3. Support image zoom, multi-face pictures Press JPEG format batch compression
4. Built-in 2 256M bytes of DDR
5. Support BT1120 video input interface
6. Support SDIO, SPI compressed video stream output interface
7.1.2V Core voltage, 3.3VIO voltage
8.TFBGA package, 185pin, size 14mm * 14mm, pin point distance 0.8mm
9. The chip power consumption is less than 0.5 watts

Xinbo Electronics · Network HD Intelligent Camera STK-1722
Based on the autonomous SVAC2.0 artificial intelligent chip SC6235, Xinbo Electronics has developed a smart network camera that meets GB35114 C-level safety requirements. The camera has built-in CA digital certificate, with the ability to manage two-way identity authentication; with video data signature capabilities; with video data encryption; you can realize high-precision facial recognition. After the first batch of public safety video surveillance products GA certification, after October 22, 2018, the GB35114 C-class product was detected by the Ministry of Public Security.

Weak noise. A large number of equipment manufacturers use universal firmware that leads to these initial passwords to be shared on different brands or different types of devices with their products. The initial password of these devices is readily checked.
2. The back door. The equipment is generally running the Linux system, and the Linux system running on the embedded CPU has root users. Both the root password is factory-factory preset, which is easy to be mastered by hackers, and hackers can be controlled by single-point breakthrough control over the system.
3. Virus attack. A large number of equipment has been infected, controlled by hackers, performs hackers such as scanning, DDoS attacks.
For the above problems, the state has introduced the world's first video surveillance system information security standard GB35114. GB35114 full name "Public Safety Video Monitoring Network Information Security Technical Requirements", this standard is officially implemented on November 1, 2018. The standard is divided into three grades in front-end equipment, the highest level is C-level: "C-level should have the ability to identify the two-way identity authentication based on digital certificate and management platform, video data signature ability and video data encryption capabilities, reach the identity and video from Real equipment, can verify that the video content is tampered with, and can achieve the video content encryption protection. "
The existing video surveillance equipment data source format has long used foreign H264 / H265 standards, while the H264 / H265 standard does not support video data signature and encryption, so GB35114 standard requires B-class and C-class front-end devices to support video data signatures and encryption. Ability of my country's autonomous SVAC2.0 standard. The maximum highlight of the GB35114 standard is signed and encrypted on the data source. When the system is threatened, it is still possible to ensure that the video surveillance system is important video image information is not out of control. The sensitive video image information does not disclose, ensuring public safety video surveillance system "Full process controllable". This is not until the ordinary camera or the A level camera.
Beijing Xinbo Electronics has been involved in the development of SVAC2.0 national standards since 2015, and is the vice chairman of the SVAC Alliance. This time you can get the first low-power C-level security network camera detection report, fully prove the deep technical accumulation of Xinbo Electronics in video security. Different from traditional cameras, C-class safety cameras have the following features:
1. Yes, it will change the original account password to digital certificates, and the initial password is the risk of 'weak password';
2. The video stream has a summary signature to prevent important video clips from being deleted, erased;
3. The video stream is encrypted, after being copied by the criminals, there is no key to not play.
Identity authentication based on digital certificate
The device identity authentication process is a signature result, the number of the number returned by the other party, the verification of the ID, the number of the number returned by the non-symmetric national algorithm SM2 and the random number generating algorithm, check sign, random number, check the ID of the other party, the number of signatures returned by the digital certificate verification, school Successful proves that both parties are legal, reaching identity, and video comes from real equipment. Safety front-end equipment is functionally implemented support for digital certificate applications, installations, updated before the number of digital certificates, and the format of the CA digital certificate is shown in the following table.
Video data signature
Video data signature uses a national SM3 password whose computing algorithm SM2 asymmetric cryptographic algorithm summarizes video I frames and other keyframes or all video frames, and transmits to the management platform for video data integrity check, verification Whether it is tampered with.
Video data encryption
Video encryption uses the national standard SM1, SM4 packet password algorithm OFB mode, and protects video data. The video key encryption key VKEK is updated when the device is registered, and is securely stored in the password module of the security front-end device from the secure video management platform. The encryption process of video data is shown below. Read the full article, original title: Xinbo Electronics: The first camera with ultra-low power SVAC2.0 smart chip gets GB35114 C test report
