Infineon OPTIGA Trust B hardware security certification solution

In the computer industry, there is a term called "handshake". The handshake is after the communication link is established, but before the start of the information transmission, the two parties in the communication need to reach a certain agreement to authenticate the identity of the "good friend" before the data transmission will officially start.

For a wider range of devices, especially between the main device and accessories, they often need to establish a connection, but do not necessarily transmit data to each other, such as mobile phone main body and battery, printer and ink cartridge, PCB substrate and daughter board, etc. So, how to "handshake" between them? Is the protocol "handshake" mentioned above secure enough to ensure the compatibility and safety of the main device and accessories?

Here, it is necessary to solemnly recommend Infineon's hardware security certification solution-OPTIGA Trust B! In addition, we also invited Infineon's digital security experts Wang Lei and Zhang Qingfeng to explain the digital device security certification in detail~

Why is equipment certification required?

The identification and management of equipment is the key to solving IoT security threats. Only in a safe and reliable environment can IoT-related services be successfully deployed. With the advent of 5G and IoT, how to achieve secure access between main devices and accessories, and how to perform secure identification and authentication has become crucial.

Take the mobile phones we are familiar with as an example. Spontaneous combustion of mobile phones often occurs because consumers fail to replace the battery through official channels, or use chargers that have not been officially certified. At the same time, with the advent of the 5G era, the fast charging technology of mobile phone manufacturers is also becoming popular, and factors such as battery heating caused by high current during fast charging should also be considered. Under these circumstances, how to ensure the safety of mobile phone charging/battery, and how to ensure that counterfeit batteries or chargers will not be used? Whether it is mobile phone batteries or chargers and other accessories, Infineon recommends effective certification measures to ensure that consumers' interests are not harmed.

Authentication security is also required between mobile phones and accessories

Infineon’s OPTIGA Trust B solution has the powerful encryption function of an embedded system with easy integration and reliable authentication. This security solution can help system and equipment manufacturers to ensure the authenticity, integrity and safety of their original products Sex. Simply put, manufacturers only need to embed Infineon’s OPTIGA Trust B chip in accessories such as batteries and chargers to achieve a "handshake" between the main device and the accessories, creating a safe, reliable, and price-competitive Encryption authentication scheme.

Principles of Infineon’s OPTIGA Trust B solution in mobile phone-battery applications

What are the advantages of security encryption?

Generally speaking, the key is the main target in a security attack. Therefore, the security protection of the key has become the core element of the system security and security chip, which requires that the security of the key can be realized in the entire product life cycle and the product supply chain. Since the hardware and design of the security chip are based on dedicated protection design and specific code specifications, it is an effective measure to increase the complexity of the security chip design to improve the security of the key, just like the "handshake" and the need to check the palm Unique information such as pattern and fingerprint.

Infineon's security certification scheme based on OPTIGA Trust B is in a leading position in the industry in terms of product security certification, effective key isolation, encryption functions, tamper resistance, and security certification production processes and personalization.

OPTIGA Trust B is a turnkey solution designed to help system and equipment manufacturers protect the authenticity, integrity and security of their original products. In addition, the production, testing and personalized prefabrication of all Infineon’s OPTIGA series of security products are completed in the CC EAL6+ environment, ensuring that the chip provides end-to-end security assurance from the source.

What support does Infineon Security Chip provide customers?

For nearly 30 years, Infineon has been committed to providing security solutions to protect user data and information. According to statistics, nearly 3 billion OPTIGA Trust series security chips have been sold all over the world, and they are widely used in various equipment certifications to "escort" the rights and interests of manufacturers and consumers!

For OEMs, OPTIGA Trust B can add simple and effective security technology to embedded systems, helping OEMs improve customer satisfaction and protect their business. More importantly, during the entire life cycle of the product, security and functionality can be protected, and the integrity, authenticity and confidentiality of information can be ensured.

In order to further strengthen the application of OPTIGA Trust B in more industry markets, promote the use of identity security certification by more customers and industries, and increase the recognition of security certification in the entire market, Infineon will launch more applicable in the future The product model Trust B SLE95250 to cover more application scenarios. In addition, Infineon has further reduced the minimum order quantity in order to support small and medium customers and provide a competitive price system; and cooperated with agent partners to further popularize the application of secure identity authentication through online and offline promotion.
