Abstract: Encryption is provided in wireless personal palm type computer devices for Internet transmitted documents despite the limited data processing and memory functions in such devices. The palm type device initially encrypts only a portion of a text document which is then wirelessly transmitted to the server computer which normally functions as the Web server, i.e. the server through which Web computer terminals are wired or connected into the Web. This Web server then further encrypts the received text document and then further transmits this further encrypted document to a terminal in said network. Preferably, the further encryption in the server involves two steps: decrypting the lower level encryption (necessitated by the limited CPU and memory resources in the palm device) to restore the text document at the server before the server may then re-encrypt the whole document using a higher level conventional 128 bit Web encryption protocols such as SSL.

Abstract translation: 尽管在这种设备中的数据处理和存储功能有限，但是用于互联网传输的文档的无线个人掌上型计算机设备中提供了加密。 手掌型设备最初仅加密文本文档的一部分，然后将该文本文档无线传送到通常用作Web服务器的服务器计算机，即Web计算机终端通过该服务器进行有线或连接到Web中的服务器。 然后，该Web服务器进一步加密所接收的文本文档，然后进一步将该另外加密的文档发送到所述网络中的终端。 优选地，服务器中的进一步加密涉及两个步骤：在服务器然后可以对整个文档进行重新加密之前，将服务器上的文本文档解密为较低级别的加密（由有限的CPU和掌上设备中的存储器资源所必需的）来恢复文本文档 使用更高级别的常规128位Web加密协议（如SSL）。
