Requirement #1: No Pre-configured Trust Relationship Every 802.11 network that uses public credentials for emergency services needs to identify itself Credentials (PSK or certificate) should not be published PSK has scaling problems and potential security issues Implementations should not require multiple certificate chains to validate trust because many devices will have small storage (e.g. phones); single certificate may be challenging Anonymous cryptography is acceptable, since the network will need to manage access rights as part of allowing session establishment |
