Abstract:
1. In a computing system environment having more than one computing device arranged together for other than collection of entropy data, a method of surreptitiously gathering entropy data, comprising: placing a network interface card (NIC) of one computing device of the more than one computing devices in a promiscuous mode; by the NIC, receiving any current packet coming to the NIC from another computing device of the more than one computing devices; by a logic component in the NIC, unbeknownst to the packet or a sender of the packet analyzing the current packets for entropy data regardless of whether the one or another computing devices ever earlier communicated while the one computing device provides an expected response to the another computing device of the more than one computing devices; and extracting and buffering said entropy data for entropy data use.
