MStar to Use Cryptography Research DPA Countermeasures to Ward Off Attacks in Set-Top Box Solutions
- Added security technologies protect tamper-resistant chips in digital home market
SUNNYVALE, Calif. & TAIPEI, Taiwan — Rambus Inc. (NASDAQ:RMBS) today announced that its Cryptography Research Division and MStar Semiconductor, Inc., a leading global semiconductor company for display and digital home solutions, have signed a license agreement for the inclusion of advanced DPA countermeasure technologies developed by Cryptography Research in MStar products. By incorporating these patented technologies, MStar’s tamper-resistant products, including set-top box chipsets, can be protected against differential power analysis (DPA) and related attacks.
“With growing threats impacting the content distribution market, we are committed to providing the highest level of security for our customers,” said Jeff Wu, Associate VP at MStar. “DPA countermeasures are integral to providing the highest level of security and now our solutions incorporate comprehensive security ingredients to protect against side-channel and other non-invasive attacks.”
DPA is a form of side-channel attack that involves monitoring the fluctuating electrical power consumption or EM emissions from a target device and then using advanced statistical methods to derive cryptographic keys and other secrets from chips. Since these types of attacks can affect set-top boxes and other consumer electronic devices, there is a growing need in the entertainment industry for advanced side-channel attack solutions to provide secure delivery of high quality content to homes.
“As it becomes easier to mount attacks using DPA, content distributors need protection against side-channel attacks to satisfy requirements in order to provide secure access to high value content,” said Paul Kocher, president and chief scientist of the Rambus Cryptography Research division. “By incorporating DPA countermeasures into their set-top box chipsets, MStar is demonstrating their commitment to deploying comprehensive security measures in the pay TV space.”
Cryptography Research DPA countermeasure technologies are designed to protect devices against certain types of attacks that can extract cryptographic keys and other sensitive data from chips in set-top boxes and other home networking products. By integrating more comprehensive security solutions into set-top boxes, unauthorized access of premium content can be prevented.
