Rambus DPA Resistant Hardware Cores, when integrated into an SoC, prevent against the leakage of secret cryptographic key material through attacks. These superior performance cores are easy to integrate into SoCs and FPGAs, providing robust side-channel resistance across different security and performance levels. Our DPA Resistant Hardware Cores support industry standard cryptographic algorithms and random number generators such as: AES, TDES, SHA-2, HMAC, RSA and ECC across multiple operating modes.
DPA Resistant AES Core
Data encryption and decryption operations are basic building blocks for most security applications. For this purpose, most systems use block ciphers, such as the public AES standard. It is well known, however, that implementations of block ciphers such as AES, as well as other cryptographic algorithms, are subject to side-channel attacks . These attacks allow adversaries to extract secret keys from devices by passively monitoring power consumption, EM emissions, or other “side channels”. Differential power analysis (DPA) is a common side channel attack that leverages power measurements.
