One-Time Pads for Secure Communication in Ubiquitous Computing

One-time pads, internet security. ubiquitous computing.


Although the Internet can be used to provide high connectivity between parties, it does not always provide strong protection for private communications. Here we describe a strong cryptographic solution to this problem using one-time pads. One-time pads provide cryptographically secure communication and can be implemented using low-power computing devices such as Pocket PC's, Palm-compatible devices, and even devices for ubiquitous computing such as Javacard and iButton. A method for the cryptographically secure transmission of data between remote users is described, and prototype implementations are presented for standard computational platforms, handheld devices and Javacard enabled devices.
