摘要
针对嵌入式软件代码的安全问题,提出了一种基于流水线技术的TDES[1-3]的嵌入式软件代码保护系统,可以有效地防范当前各种针对嵌入式软件代码的恶意窃取、修改,适用于基于I2C、SPI总线以及NAND-F lash的程序代码存储器。
To solve the security problem of software codes in embedded system, this paper proposed an encrypted/decrypted system based on pipe - line TDES, which can protect unauthorized code modifying and stealing from others. The proposed system is suitable for the memories whose interfaces are I2C and SPI from outside communication. It is also can be used in NAND -Flash memories.
