A secure connection to a router web UI is provided. In one implementation, responsive to a client request to securely connect to a router web server (RWS), the RWS generates and sends a certificate signing request (CSR) to a remote-security certificate server (R-SCS). Upon validation of the RWS, the R-SCS signs and transmits a router web UI certificate (RWUIC) to the RWS to present to the client. In another implementation, the router includes a local-SCS (L-SCS) that periodically obtains a short-lived intermediate certification authority (ICA) certificate from the R-SCS. Responsive to a client request for secure access to the RWS, the RWS generates and sends a CSR to the L-SCS for the RWUIC. The L-SCS signs the RWUIC and passes the ICA certificate and RWUIC to the RWS, which presents the certificate(s) to the client. Upon validation of the certificate(s), a secure channel between the client and RWS is established.

Digital receiver integrated local channel insertion is described. A network-connected digital receiver may be configured to bridge its network connection to extend IP connectivity via a single cable to a compatible peripheral device. In this way, the peripheral device may be connected to the local network in a controlled and automated way and, when being leveraged by an application operating on the digital receiver, the application may be granted the necessary traffic priority settings for application performance. For example, a USB, HDMI, or Ethernet connection with a peripheral device can be used by the digital receiver to provide an end-to-end managed peripheral device solution that eliminates user-intervention associated with networking, set-up, and management of the peripheral device. Various aspects of the present disclosure may be facility by a peripheral device connectivity engine that may be natively programmed into the digital receiver software stack, allowing for an intuitive user experience.

Systems, methods, and computer readable media for providing video encryption. A device may receive an unencrypted content stream. The device may identify an encryption key and an entitlement control message (ECM) from an encryption package. The device may encrypt the unencrypted content stream using the encryption key to obtain encrypted data. The device may generate an encryption stream that comprises the ECM and the encrypted data.

Systems and methods for encrypting video

Systems, methods and computer readable media for providing users with encrypted content data associated with a service are disclosed. A device may receive first content data. The device may encrypt the first content data using a first key to obtain first encrypted data. The device may generate second encrypted data by applying a cipher substitution to the first encrypted data using a second key. The device may cause to send the second encrypted data to a second device.

Countermeasure for cryptographic cribs

Systems and methods are disclosed for low power RF communications, comprising receiving an AM signal using a passive RF receiver circuit, converting the AM signal to a digital output signal using a comparator, receiving the digital output signal from the comparator, determining whether the digital output signal is valid or not using a digital signal processing circuit, and upon detection of a valid digital output signal, enabling an active RF receiver circuit for RF signal processing.

An embodiment of a method for secure escrow and recovery of media device content keys includes generating, with a first processor of a media device, an escrow key for encrypting a plurality of content keys, the content keys for encrypting instances of media content. The first processor of the media device encrypts the escrow key with a public key of a key clearinghouse. The escrow key, encrypted with the public key of the key clearinghouse, is stored in a storage location outside of the first processor of the media device.

A reprogrammable subscriber terminal of a subscription television service which can have the control program code of its control processor modified by downloading new program code from the headend. The control processor stores a boot program in an internal read only memory. Upon start up and resets, the boot program determines whether the control program should be changed from a command sent from the headend. The command, termed a parameters transactions, includes the number of expected download program code transactions required to complete the control code modification, the memory space areas where the code is to be loaded, and the channel over which the download program code transactions are to be transmitted. The channel is tuned and when the boot program receives all the download program code transactions accurately and stores them, the boot program will cause the control program to be restarted at a selected address of the new or modified control program code which has been downloaded. The boot program may download code to different configurations of subscriber terminals including those with Flash EPROM or extended memories from plug-in expansion modules.

Systems and methods are disclosed for inserting programs into broadcasted primary programs by a conditional access (CA) module that is inserted into a host device, such as a digital-ready television. The CA module utilizes primary and secondary program map tables and/or primary and secondary packet identifiers. A splicer splices the secondary packet identifiers, which is associated with a secondary program, into the primary packet identifiers, which is associated with a program, such as a broadcasted program. Additionally, the CA module may contain memory that is capable of storing the secondary program's packet identifiers and/or program map table that can be used for insertion into the primary program.

In a subscriber television system with a host terminal, the present invention allows the identification of the individual packets from two separate MPEG transport streams that have been multiplexed together for decoding by a single external conditional access or point-of-deployment (POD) module. The decoding of individual packets from two separate MPEG transport streams supports the use of multiple tuner host terminals for such functions as picture-in-picture (PIP) program viewing and the viewing of one program while recording a second program.

Systems and methods for decoding and processing back-to-back transactions for an addressable cable television tap. The addressable tap includes an input port for receiving an input signal and output ports for providing outgoing signals to receiving equipment and a controller for providing addressable per port (RF) switching. The controller is adapted to communicate with multiple addressable ports. The controller also includes storage for storing the remaining portions of partially processed commands. Further, the addressable tap includes a relay for enabling or disabling signals to the addressable output ports. Processing commands in the addressable tap includes receiving continuous commands having back-to-back transactions, from a headend and forwarding signals to receiving equipment. For a connect request, the addressable tap accepts the connect request as valid when, upon decoding each transaction, two consecutive transactions out of six are the same, and for a disconnect request, accepting the disconnect request as valid when, upon decoding each transaction, four consecutive transactions out of twelve transactions are the same.

A conditional access device is provided. The conditional access device typically includes conditional access decryption, interface, timing and control logic. The conditional access decryption logic decrypts an incoming signal for use in a consumer electronics device in accordance with previously received entitlement management messages. The interface logic receives a control signal including an entitlement management message window from a headend control system through a receiver in the consumer electronics device. The timing logic asserts an awake signal responsive to the entitlement management message window becoming active. The control logic sends a request to the consumer electronic device to activate a receiver coupled to the headend control system in expectation of receiving an entitlement management message via the control signal in response to assertion of the awake signal. The control logic also communicates the entitlement management message to the conditional access decryption logic. Other systems and method are also provided.
