A system comprises an access point and a client device. The access point receives, using near field communication (NFC) technology, a public key associated with the client device and sends, using NFC technology, a public key associated with the access point. The access point further encrypts configuration data associated with a network and sends the encrypted configuration data to the client device. The client device receives, using NFC technology, a command indicating that a public key associated with the client device is to be sent to the access point and sends, using NFC technology, the public key to the access point. The client device further receives, using NFC technology, a public key associated with the access point and configures the client device to wirelessly connect to a network associated with the access point.

Wireless configuration using passive near field communication

Methods and apparatuses are presented herein for improved operation of a Universal Integrated Circuit Card (UICC) of one or more user equipment (UE). For example, an example method of wireless communications is presented, which may include monitoring, by a UE, one or more items received from a UICC of the UE during a UICC operation. In addition, the example method may also include determining that at least one of (a) a number of the one or more items having a first item type exceeds a threshold number, or (b) an elapsed time since the UICC operation started exceeds a threshold time. Moreover, the example method may include providing, based on the determining, a notification to a user interface associated with the UE indicating that the UICC operation is ongoing.

Methods and apparatus for improving device functionality during long blocking UICC operations

Disclosed is a method for mutual authentication between a station, having a digital rights agent, and a secure removable media device. The digital rights agent is configured to initiate mutual authentication by sending a message to the secure removable media device. The secure removable media device is configured to encrypt at least a first random number using a public key associated with the digital rights agent. The digital rights agent is configured to decrypt the encrypted first random number, and encrypt at least a second random number and a first hash based on at least the first random number. The secure removable media device is configured to decrypt the encrypted second random number and the first hash, verify the first hash to authenticate the digital rights agent, and generate a second hash based on at least the second random number. The digital rights agent is configured to verify the second hash to authenticate the secure removable media device.

Method and apparatus for mutual authentication

A configuration device is disclosed for configuring a network device in a communication network. The configuration device initiates pairing operations with the network device via a short-range communication connection. The configuration device determines whether the network device is in a registered state or an unregistered state. If the configuration device determines that the network device is in the unregistered state, the configuration device establishes a secure short-range communication channel between the configuration device and the network device. The configuration device transmits a network key to the network device via the secure short-range communication channel for configuring the network device to communicatively connect to the communication network. If the configuration device determines that the network device is in the registered state, the configuration device determines whether to unregister the network device.

Network security configuration using short-range wireless communication

Disclosed is a method for mutual authentication between a station, having a digital rights agent, and a secure removable media device. The digital rights agent initiates mutual authentication by sending a message to the secure removable media device. The secure removable media device encrypts a first random number using a public key associated with the digital rights agent. The digital rights agent decrypts the encrypted first random number, and encrypts a second random number and a first hash based on at least the first random number. The secure removable media device decrypts the encrypted second random number and the first hash, verifies the first hash to authenticate the digital rights agent, and generates a second hash based on at least the second random number. The digital rights agent verifies the second hash to authenticate the secure removable media device.

Methods and systems enable receiving on mobile devices credits, tokens or coupons from mobile TV broadcast service providers. Credits may be delivered via direct unicast messages such as SMS or e-mail, or via broadcast provisioning messages. Subscription response messages may be used to deliver credits to mobile devises which transmit a request for service. Broadcast service providers may push credits to mobile devices by transmitting a solicited pull message or a credit grant push message. Credits may be sent to mobile devices within a credit response message or a long term decryption key message. Credits may be used a purchase transaction, with the broadcast service provider controlling redemption of credits by sending an a long term decryption key message via a unicast network or a short term decryption key message via the broadcast network to cause mobile devices to decrement their stored credits.

Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect a method comprises establishing a first validity range for a first key, establishing a first validity range for at least a second key, and determining if the validity range of the first key overlaps the first validity range of the at least a second key. A certificate is signed with the first validity range of the first key and the first validity range of the at least a second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of the at least a second key.
