Abstract: In at least one example, a method includes establishing, by a sniffer provisioning server (SPS) of a first wireless device, a trusted relationship between the first wireless device and a sniffer tool using a public key of the sniffer tool. An out-of-band (OOB) key exchange provisions the public key of the sniffer tool to the wireless device. The method further includes obtaining, by the SPS, key material uniquely related to a communication session established between the first wireless device and a second wireless device using a shared password. The key material excludes the shared password and a session key uniquely related to the communication session. The method further includes publishing, by the SPS, the key material over a channel to the sniffer tool based on the trusted relationship. The channel is secured using the public key of the sniffer tool.
