Side-channel attacks conducted against electronic systems are relatively simple and inexpensive to execute. An attacker does not need to know specific implementation details of the cryptographic device to perform these attacks and extract keys. As all physical electronic systems routinely leak information, effective side-channel countermeasures such as Rambus’ DPA Resistant Hardware Cores (DPARC) or DPA [...]
Side-channel attacks conducted against electronic gear are relatively simple and inexpensive to execute. Such attacks include simple power analysis (SPA) and Differential Power Analysis (DPA). An attacker does not need to know specific implementation details of the cryptographic device to perform these attacks and extract keys. As all physical electronic systems routinely leak information, effective [...]
Our DPA Workstation™ (DPAWS) 8 is a comprehensive analysis platform for the evaluation of device resistance to side-channel attacks, including SPA, DPA, HO-DPA, and EMA. Side-channel attacks are low-cost, noninvasive methods that enable attackers to extract secret cryptographic keys from electronic devices during normal operations. Build to support every stage of the side-channel analysis process, [...]
Addressing the growing demand for readily available solutions that implement Differential Power Analysis (DPA) countermeasures, Rambus Cryptography Research developed a family of semiconductor IP cryptographic cores and software libraries that are designed to protect against side-channel attack vulnerabilities. Our DPA Resistant Software Library incorporates many of the commonly used cryptographic algorithms. This library is validated [...]
