Galvanically Isolated, Power and Electromagnetic Side-Channel Attack Resilient Secure AES Core with Integrated Charge Pump based Power Management

A galvanic isolation (GI) technique for cryptographic cores is proposed to mitigate power and electromagnetic (EM) sidechannel analysis (SCA) attacks. The design uses deep N-well technology and an integrated charge pump-based power delivery and management to completely isolate VCC, VSS, and substrate nodes from the external supply and ground pins, improving the SCA resilience due to supply as well...
