A method comprising providing a plurality of links to a plurality of end-user devices communicatively coupled to a network system, a particular link of the plurality of links supporting control-plane communications between the network system and a particular end-user device of the plurality of end-user devices over one or more wireless access networks; receiving a message from a server communicatively coupled to the network system, the message comprising payload for delivery to the particular end-user device; generating an encrypted message comprising the payload and an identifier identifying a particular device agent of a plurality of device agents on the particular end-user device, the identifier configured to assist in delivering at least a portion of the payload to the particular device agent on the particular end-user device; and sending the encrypted message to the particular end-user device over the particular link.

Automated Device Provisioning and Activation

Disclosed herein are methods, systems, and apparatuses to enable subscribers of mobile wireless communication devices to view, research, select and customize service plans; to create and manage device groups, share and set permission controls for service plans among devices in device groups; to manage communication services through graphical user interfaces; to sponsor and promote service plans; and to design, manage, and control communication services through application programming interfaces.

Service Plan Design, User Interfaces, Application Programming Interfaces, and Device Management

Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.

Device-Assisted Services for Protecting Network Capacity

A method performed by an end user device associated with a service plan having a limit on usage of a network service, the method comprising storing one or more notification actions corresponding to one or more notification requests; performing a device action that reflects a past or intended use of the network service; receiving one of the one or more notification requests from a network element in response to the device action; performing one of the one or more notification actions in response to the notification request, the notification action causing the end user device to retrieve at least a portion of a notification message associated with a status of the use, the at least a portion of the notification message being separate from the one of the one or more notification requests; and presenting the notification message on a user interface of the end user device.

System and Method for Providing User Notifications

The present disclosure is directed to a system and method for selectively switching antennas of transaction cards. In some implementations, a method includes physically interfacing a card with a mobile host device including a Graphical User Interface (GUI). The card executes wireless financial transactions independent of the mobile host device. User credentials used to execute financial transactions with retail terminals are stored. Information is presented through the GUI of the mobile host device. An antenna of the card is selectively switched between an activate state and an inactive state in response to at least an event.

Selectively switching antennas of transaction cards

A portable encryption device with logon access controlled by an encryption key, with an on board cryptographic processor for reconstituting the encryption key from a plurality of secrets generated by a secret sharing algorithm, optionally shrouded with external secrets using an invertible transform resistant to quantum computing attacks. Another embodiment provides file decryption controlled by a file encryption key, with the on board cryptographic processor reconstituting the file encryption key from a version of the file encryption key which has been shrouded with a network authorization code. A method for encryption of a plaintext file by hashing, compressing, and encrypting the plaintext file, hashing the ciphertext, hashing the plaintext hash and the ciphertext hash, and sealing the ciphertext together with the resulting hash. A portable encryption device for performing the method is also disclosed.

Portable Data Encryption Device with Configurable Security Functionality and Method for File Encryption

A method and system for deploying a suite of cryptographic algorithms including: providing a legacy cryptographic interface associated with a legacy operating system and a legacy application, and supports a suite of legacy cryptographic algorithms; providing a suite of advanced cryptographic algorithms that includes one or more of an advanced asymmetric key algorithm, an advanced symmetric key algorithm, and/or an advanced hash function; providing an advanced cryptographic interface that is independent of the legacy operating system and the legacy application, backwards compatible with the legacy cryptographic interface, and capable of supporting the suite of advanced cryptographic algorithms; and transparently and automatically substituting the suite of advanced cryptographic algorithms for the legacy cryptographic algorithms through the invocation of the advanced cryptographic interface at the time of an initial performance of encrypting, hashing, digitally signing the hash of, decrypting, re-hashing, and/or validating the digital signature of an item.

Method and system for deploying advanced cryptographic algorithms

A device and method for file encryption and decryption with a cryptographic processor reconstituting a file encryption key from a version of the key which has been shrouded with a network authorization code. This meets a need for restricted communication and data containment by limiting access to a pre-defined community-of-interest, so that no one outside of that community can decrypt encrypted content.

Encryption device with configurable security functionality using network authorization code

A method for encryption and sealing of a plaintext file by hashing the plaintext file to produce a plaintext hash, encrypting the plaintext file to produce ciphertext, hashing the ciphertext to produce a ciphertext hash, hashing the plaintext hash and the ciphertext hash to produce a result hash, and sealing the ciphertext together with the result hash. This provides verification for non-repudiation and protects against undetected malware corrupting the plaintext or ciphertext files.
