Waltonchain Chooses Silictec's RFID Chips for IoT

Waltonchain reports that existing RFID chips have been unable to meet the needs of Internet of Things (IoT) development. Though a few options are available, the company indicates, prices are still high, transmission power and stability need to be improved, reception sensitivity is low and anti-interference ability is poor.

To address these problems, Waltonchain turned to the Value Internet of Things (sVIoT) concept, using RFID chips from Silicon Shenzhen Electronic Technology Co. (Silictec). The company carried out research and development regarding RFID tag and reader ICs suitable for blockchain technology applications. Currently, Waltonchain and an increasing number of companies in China are performing independent R&D into RFID chips.

The ICs are characterized by an integrated encryption and decryption acceleration module based on existing RFID technology, Waltonchain notes, as well as a communication interface protocol. The implementation will promote the application of blockchain technology in the IoT, the firm reports, and is intended to address problems with blockchain applications.

Each tag need not store node data, as it is responsible for signature verification only. Hardware automatically generates random public and private keys to ensure the security of IoT applications, and to make sure every tag is unique and authentic. The tags can reduce the amount of information stored to solve the problem of blockchain overloading with large amounts of data in IoT applications.

Hardware acceleration, meanwhile, can address the issue of slow encryption and decryption with asymmetric encryption technology. According to the company, the technology can help businesses to decentralize property and asset management in order to make data tamper-resistant.
