Rambus Cryptography Research Fellow Pankaj Rohatgi recently penned an in-depth EDN article describing the methodology behind side-channel attacks. The technique, says Rohatgi, relies on the fact that any physical realization of cryptography in hardware or software cannot be an “atomic black box” as assumed by the traditional mathematical proofs of security. Simply put, physical systems routinely leak information about the internal process of computing.

Securing silicon with a hardware-based root of trust
Steven Woo, VP of solutions marketing and distinguished inventor at Rambus, recently sat down with Anne Fisher of Embedded Systems Engineering to discuss the burgeoning security requirements of a rapidly growing Internet of Things (IoT).
Side channel attacks reportedly targeted Trusted Platform Modules
Security analysts reportedly explored how to extract private encryption keys from Trusted Platform Modules (TPMs) by “measuring electromagnetic signals emanating” from the chips. “This is what cryptographers call differential power analysis, a sophisticated side-channel attack in which spies use sensors or other devices to study the power consumption of a chip while it encrypts and decrypts information to extract the keys from it,” writes Motherboard’s Lorenzo Francheschi-Bicchierai.
EDN features Rambus CryptoManager
EDN’s Stephen Evanczuk recently confirmed that embedded systems face continuous threats by persistent individuals and entities armed with an increasingly sophisticated arsenal of tools.
The Enigma-CryptoManager Connection
We’re on the 11th floor of a tall glass building overlooking San Francisco’s iconic Market Street. Clanging cable cars ply the bustling streets below as the fading rays of a softly setting sun reflect off a row of remarkably preserved cipher machines, including an Enigma. The early cryptography platform – invented by Arthur Scherbius at the close of World War 1 – was used commercially during the 1920s before being adopted by various militaries for enciphering and deciphering secret messages, although it was famously cracked during World War II.
IDC analyzes the Rambus CryptoManager Secure Feature Management Platform
Recently licensed to Qualcomm, the Rambus CryptoManager™ platform is built around an advanced Security Engine and versatile Infrastructure Suite.
