Abstract
Data security is becoming ever more important in embedded and portable electronic devices. The sophistication of the malicious techniques used by attackers is amazingly advanced. Defensive measures for protecting a device must be even more sophisticated and robust. This paper presents an architecture that manages cryptographic keys for a secure memory interface on an FPGA. The architecture includes functional units that serve to authenticate a user, create a key with multiple layers of security, and encrypt an external memory interface using that key. Cryptographic methods built into the system include an RSA-related secure key exchange, the Secure Hash Algorithm, a certificate storage system, and the Data Encryption Standard algorithm in counter mode.
