基于ALPU-M3加密芯片的OTT软件防拷贝系统设计

OTT Software Encryption System Based on ALPU-M3 SOC

针对嵌入式系统软件代码易于复制、保密性差的缺陷,介绍了一种通过专用加密芯片实现的嵌入式软件加密方案。系统以AML8726MX SOC芯片为平台,采用专业加密芯片ALPU-M3,在Android 4.22系统上,通过软件代码和加密芯片绑定的方式,实现了OTT系统代码的不可复制性。详述了ALPU-M3 ART总线驱动在Android系统下的实现方案。

For the problem of poor confidentiality of embedded system software code, a professional security encryption solution using special encryption chip is introduced. THE System uses AML8726MX chip as the platform ,in android 4.22 system, through the software code and the encryption chip binding mode, realizes the OTT system code can not be copied. ALPU-M3 ART bus driver implementation scheme in android system is described in detail.
