Abstract: Disclosed is an apparatus, system, and method to decrypt an encrypted account credential at a second device that is received from a first device. The second device may receive a first share of a master key and the encrypted account credential from the first device. The second device may reconstruct the master key with the first share of the master key and a second share of the master key stored at the second device. The second device may decrypt the encrypted account credential with the reconstructed master key. Based upon the decrypted account credential, the second device may be enabled to access an account based upon the decrypted account credential.

Abstract: System, apparatus, and methods are provided for protecting against malicious infrastructure in a wireless communication network. A system determines a trust metric for an access point and decides to avoid communication with the access point based on the trust metric for the access point. The trust metric may, for example, be a numeric value such as a probability of trustworthiness or a categorization of trustworthiness. The system may determine the trust metric by receiving a list of access points and their corresponding trust metrics and matching a potential access point to its listed trust metric. The system may try to avoid using an untrustworthy access point's services unless it deems the services important enough to risk the communication.
