Patent ID: 10129499

Abstract:
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.
