摘要： A communications protocol is used to provide data privacy, message integrity, message freshness, and user authentication to telemetric traffic, especially to and from implantable medical devices in a body area network. Encryption, message integrity, and message freshness are provided through use of token-like nonces and ephemeral session-keys derived from device identification numbers and pseudorandom numbers.

摘要： Waveforms are digitally sampled and compressed for storage in memory. The compression of the data includes generating a truncated entropy encoding map and using the values within the map to obtain good compression. An encoder further sub-selects values to be encoded and values to remain unencoded to provide an overall compression of the data.
