Overview:
C*Core’s standard security TF card and the high-performance one are composite products designed based on C*Core’s security chips- CCM3302S and CCM3304S respectively. Both function as standard SD cards for storage and as SD-KEYs, for supporting various operating systems including Windows, Linux, and Android. They also support algorithms such as SM2/SM3/SM4/RSA1024/RSA2048,which can be widely used in PKI authentication, digital signatures, data (real-time) encryption and decryption, and secure data storage.
2.1. SD KEY
The SD KEY is a product that integrates USB KEY function into an SD card. The built-in security module provides various secure applications through the SD interface, such as certificate storage, digital signatures/authentication, access control, data (real-time) encryption and decryption, and secure data storage. It can cover all the functions of current U-shields. It extends the application area of USB KEY from PCs to handheld devices such as PDAs and mobile phones.
2.2. Security Storage
The Security TF Card provide a complete technical solution for security data storage applications, which can be customized according to customers’ requirements. The high-capacity, high-performance Security TF Card currently supports a maximum capacity of 128GB, SD2.0 protocol for high-speed storage applications. In addition, it supports national cryptographic algorithms for secuity storage. It can achieve the following functions:
(1) Data encryption
(2) Data hiding
