Definition ∞ TCP Packet Timestamping is a networking feature that adds a timestamp option to Transmission Control Protocol packets, enabling more accurate measurement of round-trip times and aiding in network performance analysis. While primarily for network optimization, these timestamps can also inadvertently provide information about the timing of network events. In specific contexts, this data could potentially be used for traffic analysis or deanonymization efforts.
Context ∞ While not directly a security feature, the data from TCP packet timestamping can become relevant in discussions about network privacy and traffic analysis, particularly concerning decentralized networks. Researchers sometimes explore how subtle timing information could be exploited by passive network adversaries. The ongoing effort is to balance network efficiency with robust privacy protections for all participants.
