Suzhou Guoxin Technology Co., Ltd., a leader in secure computing solutions, has recently applied for a new patent concerning PCIE encryption cards. The patent, titled “A PCIE Encryption Card, Its Communication Method, and Storage Medium” (Publication No. CN202410846841.8), was submitted in June 2024. This patent represents a significant innovation in secure data transmission and aims to enhance both performance and cost-efficiency in PCIE encryption technologies.

PCIE encryption cards are used to securely transfer sensitive data between computing systems, making them critical components in industries like finance, government, healthcare, and telecommunications. Suzhou Guoxin Technology’s innovation centers around a novel architecture that eliminates the need for a PCIE switch chip, a component commonly used in traditional designs to manage data flow between the encryption card and external systems. By removing this chip, Guoxin Technology has been able to significantly reduce the manufacturing costs of the encryption card without compromising on performance.

The key to the design is the use of card edge connectors, which provide an efficient and reliable method of connecting the encryption card to external host systems. These connectors are widely used in various electronic applications to establish high-speed connections between printed circuit boards and other devices. In this case, the card edge connector plays a crucial role in ensuring smooth communication between the host and the encryption card, facilitating rapid data transfer.

The encryption card features two key components: a primary PCIE chip and a secondary PCIE chip. The primary chip contains a PCIE root complex port and a first PCIE endpoint port. The first PCIE endpoint port is responsible for communication with external systems, such as servers or computers, while the root complex port manages internal communication with the secondary PCIE chip. This internal connection ensures that the card can handle complex encryption and decryption tasks without bottlenecks or delays, providing high-speed data processing capabilities.

According to the patent’s description, the architecture is designed to maintain high IO (input/output) throughput, a critical factor for encryption cards, which are often used in high-demand environments where large volumes of sensitive data need to be processed quickly. Despite the elimination of the PCIE switch chip, the design ensures that the card can handle the same level of throughput as traditional designs. This makes it an attractive option for industries that require both high performance and cost-efficiency.

The use of card edge connectors in this design not only improves the overall efficiency of the card but also makes it easier to integrate into existing systems. As card edge connectors are a standard component in many industries, companies adopting this new encryption card will not need to make significant modifications to their hardware infrastructure, further reducing costs.

This patent marks an important step forward for Suzhou Guoxin Technology, which has been steadily building its reputation as a leader in the secure computing space. The company’s focus on reducing costs while maintaining high performance will likely make its encryption card a popular choice in industries where data security is paramount.

In addition to the encryption card itself, the patent also covers a communication method and storage medium designed to enhance the card’s overall functionality. This method ensures that data is transferred securely between the card and the host system, while the storage medium provides a secure environment for storing sensitive encryption keys and data.

As data security continues to be a major concern for businesses and governments worldwide, innovations like Suzhou Guoxin Technology’s PCIE encryption card are likely to play a crucial role in protecting sensitive information. With cyber threats becoming more sophisticated, the demand for high-performance, cost-effective encryption solutions is only expected to grow.

By leveraging card edge connectors and eliminating unnecessary components, Suzhou Guoxin Technology has positioned itself at the forefront of this rapidly evolving field. The company’s latest patent not only enhances the capabilities of encryption cards but also sets a new standard for cost-efficiency and performance in secure data transmission.
