【应用笔记】AN512:使用Stratix III器件的设计安全特性(AN 512: Using the Design Security Feature in Stratix III Devices) 在如今的充满高度竞争的商业和军事环境中，对数字设计师们来说设计安全来说是一个重要的考量。 In today’s highly competitive commercial and military environments, design security is becoming an important consideration for digital designers. As FPGAs start to play a role in larger and more critical system components, it is ever more important to protect the designs from unauthorized copying, reverse engineering, and tampering. Stratix® III devices address these concerns with the ability to decrypt a configuration bitstream using the 256-bit Advanced Encryption Standard (AES) algorithm, an industry standard encryption algorithm.
