A terminal device may execute a first attempt process in which the terminal device attempts to communicate with a server on the Internet via a communication interface by using a specific LAN to which the terminal device is currently connected; and in a case where the attempt to communicate with the server is successful in the first attempt process, send connection information to a communication device different from the terminal device, the connection information being for connecting the communication device to the specific LAN, wherein in a case where a specific condition is fulfilled, the connection information is not sent to the communication device, the specific condition including a condition that the attempt to communicate with the server fails in the first attempt process.

A user device having a security context with a first network based on a first key may establish a security context with a second network. In a method, the user device may generate a key identifier based on the first key and a network identifier of the second network. The user device may forward the key identifier to the second network for forwarding to the first network by the second network to enable the first network to identify the first key at the first network. The user device may receive a key count from the second network. The key count may be associated with a second key forwarded to the second network from the first network. The user device may generate the second key based on the first key and the received key count thereby establishing a security context between the second network and the user device.

The present disclosure generally relates to managing access to credentials. In some examples, an electronic device authorizes release of credentials for use in an operation for which authorization is required. In some examples, an electronic device causes display of one or more steps to be taken to enable an input device for user input. In some examples, an electronic device disambiguates between commands to change the account that is actively logged-in on the device and commands to cause credentials to be released from the secure element.

Systems and method are provided for mitigating hacking of restricted access telecommunication services. In response to an authentication response from a user device, an authentication failure type and authentication failure frequency may be determined. Based on the authentication failure type and authentication failure frequency, the user device is blocked from accessing the telecommunication service for a predetermined period of time, preventing the service from being congested by recurring unauthorized users.

An electronic device may include at least one wireless communication module configured to transmit and receive a wireless signal; a memory electrically configured to store instructions; and at least one processor operatively connected to the at least one wireless communication module and the memory, the at least one processor being configured to execute the instructions to: based on an attempt to connect to an access point (AP), identify whether a pairwise master key security association (PMKSA) for the AP, generated based on to a previous connection of the electronic device to the AP, is present, and based on identifying that the PMKSA is present, determine whether to reuse a pairwise master key (PMK) stored in the PMKSA by comparing a lifetime of the PMK with a margin time in which a use of the PMK is guaranteed.

A system and method for authenticating users of a digital device includes an authentication device attached to an authorized user. The authentication device includes one or more motion sensors and acts as a user identity token. To authenticate with a digital device, the user performs one or more interactions with the digital device using the hand associated with the authentication device. The digital device correlates the inputs received due to the interactions with the user's hand and/or wrist movement, as measured by the authentication device. Access to the digital device is allowed if the inputs and movements are correlated.
