DesignHub™ Public-Key Cryptographic IP supports secure boot, authentication, key agreement, digital signatures and data protection with RSA and a broad selection of elliptic-curve algorithms. Efficient cryptographic operations and protocol acceleration reduce the load on the main processor. Implementations can be selected for performance, area and security requirements, with flexible chip integration and optional protection against physical attacks.
Binary-field ECC solutions are also available in addition to the prime-field and 25519 curves listed below.
