    • A device (200, 2200) for improved security includes a processor (200) and a secure writeable memory (2245) coupled to said processor (200) and including code (2240) to download a loadable security kernel to the processor (200), authenticate the loadable security kernel, and transfer the kernel so that the kernel begins at a predetermined address inside the secure writeable memory (2245) only if the authentication is successful. A process (2400) of manufacturing a target communication device (2310) having a memory space having a secure writable portion (2245) of the memory space, the manufacturing process (2400) using a host machine (2330). The manufacturing process (2400) includes downloading (2540) the loadable security kernel from the host machine (2330) to the memory space at the target (2310). The loadable security kernel has a flashing entry point. The process also includes authenticating (2590) the downloaded loadable security kernel received at the target (2310), moving (2640) the loadable security kernel in the memory space provided the authenticating is successful (2610), wherein after the moving (2640) the loadable security kernel is in the secure writable portion (2245) of the memory space; and jumping (2650) to a predetermined location in the secure writable portion of the memory space, the predetermined location coinciding with the flashing entry point of the security kernel as moved.
    • 用于改进安全性的设备(200,2002)包括耦合到所述处理器(200)的处理器(200)和安全可写存储器(2245),并且包括用于向所述处理器(200)下载可加载安全内核的代码(2240) 验证可加载的安全内核,并传输内核,使得只有在认证成功的情况下,内核才能在安全可写存储器(2245)内的预定地址开始。 一种具有存储空间的目标通信设备(2310)的处理(2400),该存储空间具有存储空间的安全可写部分(2245),该制造过程(2400)使用主机(2330)。 制造过程(2400)包括将可加载的安全内核从主机(2330)下载(2540)到目标(2310)处的存储器空间。 可加载的安全内核具有闪烁的入口点。 该过程还包括认证(2590)在目标(2310)处接收的下载的可加载安全内核,移动(2640)提供认证成功的存储器空间中的可加载安全内核(2610),其中在移动(2640)之后 可加载的安全内核在存储器空间的安全写入部分(2245)中; 和跳跃(2650)到所述存储器空间的所述安全可写部分中的预定位置,所述预定位置与所述安全内核的闪烁入口点一致。
