Winbond licenses DPA countermeasures from Rambus Cryptography Research
Winbond Electronics has licensed differential power analysis (DPA) countermeasures from Rambus’ Cryptography Research division. By implementing DPA countermeasures in flash memory components, Winbond will ensure the data integrity of products that run applications requiring a high level of security – including mobile payments, premium content, automotive and the 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,” Chester Hwang Business Unit Leader of Secure memory solutions of Winbond explained in an official press release (insert press release link here). “Rambus DPA countermeasures ensure that Winbond’s TrustMETM flash memory components are protected from these types of attacks.”
Paul Kocher, chief scientist of the Rambus Cryptography Research division, expressed similar sentiments.
“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,” he said. “Our DPA countermeasures allow Windbond to develop DPA resistant flash memory components that are capable of passing high-level industry security certifications.”

As we’ve previously discussed on Rambus Press, physical electronic systems routinely leak information about the internal process of computing. In practical terms, this means attackers can exploit various side-channel techniques to gather data and extract secret cryptographic keys.
As such, the Rambus Cryptography Research division has designed a range of DPA countermeasures that offer a combination of software, hardware and protocol techniques specifically designed to protect tamper-resistant devices from side-channel attacks. These include leak reduction, incorporating randomness, generating amplitude and temporal noise, as well as executing protocol-level countermeasures.

Winbond to License DPA Countermeasures from Rambus Cryptography Research
DPA Countermeasures will protect data integrity in flash memory components against security attacks
SUNNYVALE, Calif. – September 21, 2015 – 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.

Designing lightweight cryptography for the IoE
Ernest Worthman of Semiconductor Engineering recently noted that we have entered an age where technology is expected to do more, faster, anonymously, and often invisibly.
“It’s supposed to use less power, with smaller footprints, unobtrusively and intuitively,” he explained. “And all that needs to be protected with cryptography.”
However, as Simon Blake-Wilson, VP of products and marketing for Rambus‘ Cryptography Research Division points out, “the lower the security level, the more has to be compromised.”
To mitigate the effects of that compromise, says Worthman, the industry is developing and implementing lightweight ciphers, cryptography primitives and lightweight processor cores.
“There are a lot of MPU architectures that exist in the archives that have the potential to serve as lightweight crypto processors,” he told Semiconductor Engineering. “However, it seems to be difficult to bring together the right compact core and a workable instruction set architecture (ISA) that is both compact, and code-efficient enough to run on the core.”
As such, the semiconductor industry is currently exploring the possibility of employing non-standard approaches.
“Standard cryptography approaches on light devices are not feasible, mainly because the pin count is so restricted, the amount of power they draw, and the amount of energy available to them,” said Pankaj Rohatgi, director of engineering at Rambus’ Cryptography Research Division. “[Nevertheless], the need for IoE devices, especially in sensors and tags, is mushrooming and the awareness of cryptography for these devices is growing as well.”
As Blake-Wilson points out, one has to look at three things when designing lightweight cryptography for the IoE.
“[These include] the algorithms used, how to securely implement them, and, finally, how one manages those algorithms and the keys. When you look at lightweight cryptography for the IoE, you have to look at those three areas.”
Chowdary Yanamadala, VP of business development at ChaoLogix, expressed similar sentiments.
“No matter how light the chips are, there are two security features that they must contain—encryption and authentication.”
Fortunately, progress is being made, despite the myriad of challenges associated with building lightweight cryptography processors for the IoT.
According to Worthman, one potential solution could focus on designing a custom hardware platform, which would likely be most suitable for high-value targets. Meanwhile, a software-centric approach would allow hardware platforms to implement a wide range of cryptographic options. Nevertheless, as Worthman explains, a software approach would be “computationally burdened,” which often translates into sub-par performance.
“So the development has been around finding the magic bullet that brings hardware and software together to create a practical platform,” he added.

Rambus Reveals Smart Data Acceleration Research Program
Slated to improve performance and power efficiency for data centers
SUNNYVALE, Calif. – September 14, 2015 – Rambus Inc. (NASDAQ:RMBS) today announced the Smart Data Acceleration (SDA) Research Program designed to tackle major issues facing data centers in the age of Big Data. The SDA Research Program has been exploring new architectures for servers and data centers that are optimized for rack-level Big Data computation, targeting significant improvements in performance and power efficiency, as the industry brings computing closer to data.
“Modern servers are out of balance with today’s needs – data centers are under stress due to escalating demands of real-time access to large amounts of information driven by Big Data and new applications,” said Laura Stark, senior vice president and general manager of the Emerging Solutions division at Rambus. “This research platform focuses on architectures that offload computing closer to very large data sets at multiple points in the memory and storage hierarchy.”
As part of the program, Rambus has created a platform to investigate system architectures that include software, firmware, FPGAs and large amounts of memory. The platform can be used to test new methods to optimize and accelerate data analytics for extremely large data sets.
With use cases including real-time risk analytics, ad serving, neural imaging, transcoding and genome mapping, the Rambus SDA Research program is a key technology investment for the next generation of data centers.
