Copyright Protection Model of Embedded Systems and Its Applications in Digital TV Set-Top-Box

Embedded system copyright protection model based on specific Crypto Memory IC is presented in this paper at first. After analyzing the security performance of the model, compiler linking and software encryption are used to optimize the security performance of the synthesis model of hard ware and software. Combining with the encryption application of digital TV Set-Top-Box, the key technologies are illustrated in detail at last. The applications of this model proposed are proven to have features such as high security and low cost.
