CodeSigner DOCSIS® Signing Tool

Guarantee the security of your cable modems and R-PHY devices.

Every DOCSIS® cable modem and R-PHY device comes, as standard, with certified software. Yet, what about updates and changes? Make sure to install correct and trusted software on each cable modem and R-PHYD deployed in the field. The CodeSigner DOCISIS Signing tool can help confirm your commitment to software security.

CodeSigner

DOCSIS® 3.1 introduces a whole new range of possibilities for signing and co-signing images. Manufacturers will provide, as the specification requires, signed software images.

Vendors who choose to create signed software images can rely on CodeSigner to make the signing process easier, while the tool helps them test specification compliance. Cable service operators, for their part, can use CodeSigner to co-sign the software images and thus ensure easy Secure Software Download (SDD) for all vendors and types of modems.

Simplify Config File Management

By including your co-signer CVC (DOCSIS 3.0) or CVC chain (3.1) in the config file, you’ll enable Secure Software Download (SSD) for all vendors/types of modems. In this way, you avoid the complex procedure of including the correct manufacturer CVC of each vendor in the config file of that vendor’s modems.

Ensure all software images are certified

Software updates usually contain bug fixes and/or additional features. While the SSD mechanism is part of the certification process, there is no guarantee that the new software image is also certified. Co-signing the software is a good formal step to conclude your own test procedures on the new software and confirm it is secure.

Highlight quality and security to your customers

Including your co-signer CVC in the config file, also ensures that no co-signed images are allowed on your network. Hence, co-signing the software images is an extra guarantee of your devices’ quality and security. Customers will appreciate this quality and security ‘label’.
