Abstract: A method for encryption in a wireless communication system includes encrypting, at a base station, data of a physical layer control channel using at least one of a control channel type, a radio resource aggregation level of the control channel, a radio resource index of the control channel, or a subcarrier frequency of the control channel; and transmitting the encrypted data to a user equipment (UE), where the UE is in a cell of the base station.

Abstract: There is provided a method for secure communications. The method includes a computing device receiving a notification comprising a message, a counter value, a signature signed by a signer and based on the message and the counter value, and an indication of the signer. The device obtains a current counter value based on an identity of the signer, checks the signature and compares the counter value with the current counter value; and, if the counter comparison and the signature checking is successful, accepting the message.

Abstract: A system and method for transmitting uplink channels for a plurality of uplink component carriers(UL CCs). Based upon a total transmit power exceeding a maximum allowed power, a transmit power is reduced for uplink channel transmissions that comprise Uplink Channel Information (UCI); and transmit power is not reduced for one or more other uplink channels that do not include comprise Uplink Channel Information (UCI). The uplink channel transmissions and the one or more other uplink channels are simultaneously transmitted in multiple uplink (UL) component carriers (CCs).

Abstract: The present disclosure relates to systems and methods for secure communications. In some aspects, a method of signalling an interception time period is described. At least one keying information used by a KMF to regenerate a key is stored. A start_interception message is signaled from an ADMF to a CSCF. A halt_message is signaled from the ADMF to the CSCF.

Abstract: Systems, methods, and software can be used to prevent messaging attacks. In some aspects, a scanning short message is sent to a UICC associated with a mobile device. A response short message is received in response to the scanning short message. The UICC is determined to be at risk to attacks based on the response short message. In response to determining that the UICC is at risk to attacks, a notification is generated. In some cases, the notification is sent to a DMS. Alternatively or in combination, the notification is displayed on the mobile device. In response to determining that the UICC is at risk to attacks, a firewall application is installed on the mobile device. The firewall application is configured to process an incoming short message addressed to the UICC.

Abstract: Systems, methods, and software can be used to share content. In some aspects, a message is received at an electronic device from a sender. A first type 0 short message service (SMS) message is sent, from the electronic device to the sender. The first type 0 SMS message indicates an authentication request for the message. A second type 0 SMS message is received at the electronic device. The second type 0 SMS message indicates that the message is authenticated.

Abstract: Systems, methods, and software can be used to share content. In some aspect, an electronic device selects a base station to camp on. A first message is sent from the electronic device to the base station. The first message is addressed to a server and requests the server to send a second message to the electronic device. Whether the electronic device receives the second message from the base station within a threshold time period after the first message is sent is determined. The electronic device determines that the base station has a security risk based at least in part on whether the second message is received within the threshold time period.

Abstract: A system that incorporates teachings of the subject disclosure may include, for example, accessing a group of de-coupling data stored in a memory of a communication device where the group of de-coupling data is mapped to corresponding use cases associated with the communication device, selecting de-coupling data from among the group of de-coupling data according to a determined use case of the communication device, generating a pre-distortion signal according to the selected de-coupling data, combining the pre-distortion signal with RF signals to generate pre-distorted RF signals, and transmitting the pre-distorted RF signals via a multi-port antenna of the communication device. Other embodiments are disclosed.

Abstract: The present disclosure describes methods and systems for establishing a Session Initiation Protocol Session. One method includes transmitting a first message requesting authentication configuration information; in response to the first message, receiving a second message that includes the authentication configuration information; transmitting a third message that includes authentication information based upon the received authentication configuration information; receiving an authentication challenge request that is formatted according to the second protocol; and in response to receiving the authentication challenge request, transmitting an authentication response to the second network node.
