Abstract:
1. A method of adding entropy to an entropy pool of a random number generator in a network connected device, the method comprising: identifying a first packet of network data as encrypted; selecting the first packet for use; extracting a variable amount of data from the first packet, the extracting includes generating a first random number indicating an offset into the first packet, generating a second random number indicating a length, and extracting data from the first packet starting at the offset generated and for the length generated; stirring the extracted data into the entropy pool of the random number generator; selecting a second packet for use from the encrypted network data; extracting a variable amount of data from the second packet different than the variable amount of data extracted from the first packet, the extracting includes generating a third random number indicating an offset into the second packet, generating a fourth random number indicating a length, and extracting data from the second packet starting at the offset generated and for the length generated; and stirring the extracted data from the second packet into the entropy pool of the random number generator.
