Methods and apparatus to support reliable digital communications without integrity metadata

Abstract:

Before sending a message to a destination device, a source device automatically uses a pattern matching algorithm to analyze entropy characteristics of a plaintext version of the message. The pattern matching algorithm uses at least one pattern matching test to generate at least one entropy metric for the message. The source device automatically determines whether the message has sufficiently low entropy, based on results of the pattern matching algorithm. In response to a determination that the message does not have sufficiently low entropy, the source device automatically generates integrity metadata for the message and sends the integrity metadata to the destination device. However, in response to a determination that the message has sufficiently low entropy, the source device sends the message to the destination device without sending any integrity metadata for the message to the destination device. Other embodiments are described and claimed.
