Conventional wireless interface (WiFi) controllers cannot resolve authentication for trusted client devices without calculation from a host processor. Leaving the host processor on or awaking it from a sleep state each time a non-authenticated trusted client device attempts to connect wastes power. A hostless authenticated wake service allows a host controller to enter a sleep state while the WiFi controller responds to multicast domain name service-service discovery (mDNS-SD) queries from trusted client devices. Once a client device is authenticated, the WiFi controller may respond to a trusted client request to awake the host processor for further command processing and service provision. Not only does this approach reduce power consumption by allowing the host processor to remain in the sleep state, it allows trusted client devices to discover its presence while ensuring security.

Disclosed is a system and method for securely storing a Wi-Fi password or similar WLAN security credentials on a device, such as a camera. The password is secured by encryption using an encryption key generated from the Service Set Identifier (SSID) of the network. A one-way-hash of the SSID is stored in a non-volatile memory of the device, but the plaintext SSID is not stored on the device. At a later time, the device may detect the SSID of the network and hash the detected SSID. If the hash matches a previously stored hash, an encryption key is generated from the SSID and the encryption key is used to decrypt the password associated with the matching hash. Without knowledge of the SSID, an attacker who gains access to the device will not be able to recover the password from the hashed SSID and the encrypted password.

Securing wireless network credentials without a user login

Timing metadata is generated and added to captured video to compensate for synchronization error between video captured concurrently from multiple cameras. A wireless beacon including timer data is transmitted from an access point to each station camera. A radio circuit of the station camera synchronizes to the timer of the access point based on timing information in the wireless beacon. An image processor in each station camera includes an image processor timer separate from the radio circuit timer. During video capture, timing metrics are generated indicating deviation between the image processor timer and the radio circuit timer. The timing metrics are stored as metadata and can be used to compensate for synchronization error in post-processing.
