Winbond to License DPA Countermeasures from Rambus Cryptography Research

DPA Countermeasures will protect data integrity in flash memory components against security attacks

SUNNYVALE, Calif –  Rambus Inc. (NASDAQ:RMBS) today announced that Winbond Electronics Corporation, a leading maker of top quality memory solutions, has licensed Rambus Cryptography Research differential power analysis, or DPA, countermeasures to protect industry-leading, flash memory components. By implementing Cryptography Research DPA countermeasures, Winbond ensures the data integrity of products that run applications requiring a high level of security, including mobile payments, premium content, automotive, and Internet of Things (IoT).

“As we set out to provide our customers with the most secure hardware solutions, we know that protecting against the threat of side-channel attacks is a priority – especially in the mobile payments arena,” said Chester Hwang Business Unit Leader of Secure memory solutions of Winbond “Rambus DPA countermeasures ensure that Winbond’s TrustMETM flash memory components are protected from these types of attacks.”

The DPA countermeasures from Cryptography Research have enabled Winbond to meet today’s rigorous hardware security requirements. Specifically, DPA countermeasures will protect against risks in Winbond’s series of TrustMETM flash memory components.

“As mobile devices or IoT objects increasingly manage sensitive data and encrypted transactions, it becomes more important than ever to safeguard them against security threats,” said Paul Kocher, chief scientist of the Rambus Cryptography Research division. “Our DPA countermeasures allow Windbond to develop DPA resistant flash memory components that are capable of passing high-level industry security certifications.”

DPA is a type of side-channel attack that monitors variations in the electrical power consumption or EM emissions from a target device. These measurements can then be used to obtain cryptographic keys and other sensitive information from chips. Rambus DPA countermeasures offer a proven solution to warding off these attacks, protecting devices against the extraction of critical, private data.
