    • 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。

    • An electronic circuit includes a more-secure processor having hardware based security for storing data. A less-secure processor eventually utilizes the data. By a data transfer request-response arrangement between the more-secure processor and the less-secure processor, the more-secure processor confers greater security of the data on the less-secure processor. A manufacturing process makes a handheld device having a storage space, a less-secure processor for executing modem software and a more-secure processor having a protected application and a secure storage. A manufacturing process involves generating a per-device private key and public key pair, storing the private key in a secure storage where it can be accessed by the protected application, combining the public key with the modem software to produce a combined software, signing the combined software; and storing the signed combined software into the storage space. Other processes of manufacture, processes of operation, circuits, devices, wireless and wireline communications products, wireless handsets and systems are disclosed and claimed.
    • 电子电路包括具有用于存储数据的基于硬件的安全性的更安全的处理器。 较不安全的处理器最终利用数据。 通过在更安全的处理器和较不安全的处理器之间的数据传输请求 - 响应布置,更安全的处理器赋予较不安全的处理器上的数据更大的安全性。 制造过程使得具有存储空间的手持设备,用于执行调制解调器软件的较不安全的处理器以及具有受保护应用和安全存储的更安全的处理器。 制造过程涉及产生每设备私钥和公开密钥对,将私钥存储在安全存储器中,在该存储器中可以被受保护的应用程序访问,将公开密钥与调制解调器软件组合以产生组合的软件, 组合软件; 并将签名的组合软件存储到存储空间中。 公开并要求保护其他制造工艺,操作过程,电路,设备,无线和有线通信产品,无线手机和系统。
