A 435MHz, 2.5Mbps/W Side-Channel-Attack Resistant Crypto-Processor for Secure RSA-4K Public-Key Encryption in 14nm CMOS

A 0.072mm ² SCA-Resistant RSA-4K crypto-processor fabricated in 14nm CMOS achieves peak encryption throughput of 0.08Mbps at 750mV, 25°C. Exponent magnitude/timing randomization with dynamic RF addressing provide 711× lower means-separation in current/EM trace magnitudes, reducing attacker's accuracy to an ineffective random guess classification while limiting area/performance overhead to 3%.
