A method is presented for secure communication, the method including generating a signature using a private key, a nonce, and at least one of an identifier and a key component; and transmitting the signature, the nonce, a security parameter, and the at least one of the identifier and the key component, wherein the security parameter associates a user identity with a public key, the public key being associated with the private key.

Securing method for lawful interception

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.

Establishing a session initiation protocol session

A system and method for permuting known and unknown message bits before encoding to provide a beneficial rearrangement of bits. Such a method can improve distance properties in the resulting subcode. In various embodiments, the structure of a beneficial rearrangement is dependent on the parameters of how known and unknown bits are grouped and on the specific type of code being used. Given these two parameters, the message bits can be rearranged to more efficiently leverage any apriori knowledge.

Message rearrangement for improved wireless code performance

A method of processing a notification that is broadcast by a source server is disclosed. The method includes: receiving, at the computing device, the notification, the notification containing a first message; storing the first message in a message store; determining that the first message is a repeated message of a previous message that was received at the computing device prior to receiving the notification; and associating a message counter value of the first message with the previous message and a message counter value associated with the previous message in the message store.

Method for validating messages

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.

Authenticating messages

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.

Detecting and warning of base stations with a security risk

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.

Encryption in wireless communication systems

A method for receiving public warning system (PWS) data includes receiving, at a user equipment (UE), a public warning system (PWS) message. The UE determines that the PWS message is a type 2 PWS message. The type 2 PWS message indicates that type 2 PWS data is delivered using a type 2 PWS data delivery mechanism. The type 2 PWS data is received using the type 2 PWS data delivery mechanism.

Receiving public warning system data

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.

A method, device and a computer program product operable in a communications network to provide enhanced public warning system (PWS+) messages to a communication device over the current PWS system is disclosed. The method includes generating, at a server or network device, at least one public warning system (PWS) message and at least one enhanced PWS (PWS+) message, and associating the PWS+ message with the at least one PWS message. The at least one PWS+ message and the PWS message are transmitted via a communications network to the communication device.

Enhanced public warning system to provide rich content

Systems and apparatuses involve implementing methods that may include receiving, by enhanced user equipment (eUE), an assignment of Resource Blocks (RBs) from an eNodeB (eNB), wherein the eUE is configured to receive full-duplex transmissions; for each assigned RB, measuring interference caused by uplink transmissions from one or more legacy UEs; and reporting, to the eNB, the measured interference. The present implementations may provide an eUE-based approach, an eUE and eNB interactive approach, an eUE baseband approach, and an eUE analog approach to reducing interference for full duplex enabled mobile devices.
