Cryptography Research, the security division of Rambus, and Entropic, a specialist in semiconductor solutions for the connected home, signed a patent licence agreement allowing for the use of the Cryptography Research side-channel attack countermeasures in Entropic’s integrated circuits. The Cryptography Research patented technology will protect Entropic’s set-top box system-on-a-chip (SoC) products against differential power analysis (DPA) and related attacks.

This agreement builds on the previous agreement between the two companies with Entropic already licensing the Cryptography Research CryptoFirewall tamper-resistant core for set-top boxes.

“While high value content enhances the Pay-TV experience, it also carries with it substantial risk for our OEM and Service Provider customers,” said Matt Rhodes, senior vice president, Global Marketing, Entropic. “Today’s premium programming requires strong protection systems and CRI’s DPA countermeasure technology provides an essential foundation for any Conditional Access or Digital Rights Management system.”
