Rambus partners with Cybertrust to deliver secure key provisioning and security services for connected devices

Rambus  has announced a partnership with Cybertrust. Cybertrust provides Public Key Infrastructure (PKI) solutions and is a subsidiary of SoftBank Technology Corp. The aim of the partnership to deliver secure key provisioning and security services for connected devices spanning from enterprise multi-function printers to connected cars.


This collaboration combines the Rambus CryptoManager Infrastructure and the Cybertrust PKI solution, to secure communication from device-to-cloud and for over-the-air (OTA) software updates. The joint solution brings two  security providers together to deliver a turn-key platform that addresses the increasingly complex security challenges for connected devices.

CryptoManager Infrastructure enables the secure provisioning of device services throughout the distributed manufacturing supply chain. Device services are a broad range of secure transactions, including key delivery and
programming, protection of debug modes, and chip feature management.

Key services include:

  • Provisioning of keys during semiconductor and device manufacturing
  • Controlling critical test and debug traces
  • Enabling feature and device settings
  • Securing in-field key provisioning
  • Over-the air-updates of device software and firmware

A public key infrastructure (PKI) supports the distribution and identification of public encryption keys, enabling users and computers to both securely exchange data over networks such as the Internet and verify the identity of the other party.

Cybertrust is a comprehensive PKI vendor that offers a wide range of products and services, including the issuance of certificate authorities and the outsourcing of certificate issuance services.

Additional PKI services and solutions include:

  • UniCert of in-house certificate authority issuance service
  • Customer-branded certificate authority (Managed PKI)
  • Cybertrust-branded user certificate issuing service (Personal ID)
  • Terminal authentication certificate issuing service (Device ID)

As the number of ECUs, interconnected via CAN, MOST and other IVNs,  is increasing in the modern vehicles, the role of software has become more and more important, due to its growing amount and complexity. This is where OTA software updates can help by providing the much-needed upgradability. But security is a critical issue, OTA software updates must be secure and provide update reliably and protect the data transmitted to and from the vehicle. So coming together of companies like Rambus and Cybertrust is important.
