Abstract
A method and related system is disclosed for integrating a positioning system into the key management structure and within the information security boundary of an End Cryptographic Unit (ECU). This integration enables key management security rules written to include the ECU's trusted physical location and trusted time in determining if and with which key a message should be encrypted or decrypted. Only appropriate messages for a bounded geographic area would be decrypted and received by the ECU. The trusted positioning system allows extending functionality to allow position-enhanced authentication capabilities. Outgoing messages are cryptographically bound with the ECU's trusted position information as well as an accurate time stamp.
