DeepCover embedded security solutions protect sensitive data with multiple layers of advanced physical security and provide high-security storage for secret authentication keys. Using the FIPS 180 SHA-256-based authentication algorithm, the DS28C22 combines strong cryptographic authentication, bidirectional, secure challenge-response authentication, and small message encryption. Through bidirectional authentication, the host and peripheral authenticate each other, protecting the IP address on the peripheral from an inauthentic host attempting to modify its operation. The DS28C22 enables unparalleled security for many applications, including peripherals/disposables, sensors, network equipment, IP licenses, and industrial applications such as programmable logic controllers (PLCs).
Key Advantages
• Robust security protects IP from compromise by counterfeiters or hackers: A bidirectional security model enables two-way authentication and encryption between the host system and the embedded DS28C22 slave. Strong die-level protection securely stores the authentication key.
• Simple and comprehensive programming: Includes 3K-bit user memory with four user-programmable protection modes. The SHA-256 option allows customers to securely control the final product's features through data configuration.
• Added security with factory pre-programming: Maxim's optional DS28C22 pre-programming service prevents supply chain vendors from compromising the solution and ensures the cryptographic keys remain unexposed.
• Fast and secure encryption process: The DS28C22 includes a unique hardware-accelerated engine for SHA calculations.
