摘要： A secure digital communications method is provided in which a Certificate Authority generates an improved RSA key pair having a modulus, a public key exponent, a public key, and a private key. The public key exponent can contain descriptive attributes and a digital signature. The digital signature can be responsive to the descriptive attributes and the modulus. A secure session can be established between a first system and a second system, within a secure digital communication protocol. The second system can verify the digital signature to authenticate the public key.

摘要： A method is provided for providing a new master key to devices in a Thread network for an Internet of Things (IOT). To provide the new master key, Device Provisioning Key (DPK) is generated from a Network Seed Key (NSK) known to a Commissioner and Leader in a local network. The Commissioner provides the DPK as a unique per-device key to each device in the network to establish a secure session. The DPK is derived from the NSK as follows: DPK=OWF(NSK, ID), wherein OWF is a One Way Function, and ID is a unique device identifier for each device. The new master key can then be sent from the commissioner to the new devices to establish a secure session created using the DPK.

摘要： A digital rights management system is provided that includes a receiving device for receiving an encryption key request from a client device, a first database for storing a set of supported security capabilities corresponding to client device, a second database for storing a set of required security capabilities corresponding to at least one of the encryption key and content associated with the encryption key, a content management system for establishing rules to determine the set of required security capabilities corresponding to content, and a processing device. The processing device may be configured to identify the set of supported security capabilities corresponding to the client device and identify the set of required security capabilities corresponding to the content associated with the encryption key. The content management system may be configured to configure the set of supported security capabilities and configure the set of required security capabilities.

摘要： A method and system are provided for improved distributing of a complete software image to all electronic devices of a certain type or model while using encryption to limit its use to specific ones of those devices. In the method, the entire software image is encrypted with a global key and the encrypted software image is distributed to all devices which have the capability of running that software. The global software decryption key for decrypting the software image is uniquely encrypted for every device that is authorized to use the software and the encrypted global software key is distributed to those devices from a field or factory provisioning server across a point-to-point connection.

摘要： A system is provided wherein a network control access device that is already in a network, called a Gatekeeper, generates a random short password in the form of a series of audio or visual cues that are visible to the user of a joining device. The joining device can be a simple one button device, or even a no-button device that is part of the internet of things (IOT) standard. The response to each cue can be entered by the user on a single-button joining device. For a no-button joining device, an alternate input method may be utilized on the joining device in response to the audio and visual cues. Alternatively, a password can be generated by the no-button joining device and be entered by the user one bit at-a-time directly onto the Gatekeeper keypad. Once the password is received, the Gatekeeper performs a password verification procedure.

摘要： An external trusted time source is implemented over a network for conditional access system (CAS)/digital rights management (DRM) client devices. A client device includes untrusted software and a trusted execution environment (TEE) for processing an entitlement management message (EMM) that includes an epoch sequence number (ESN) transmitted from an EMM server using a first network connection. A remaining client key set (CKS) lifetime value is stored and updated in the TEE based on the ESN processed.
