Current Balancing Random Body Bias in FDSOI Cryptosystems as a Countermeasure to Leakage Power Analysis Attacks

This paper identifies vulnerabilities to recently proposed countermeasures leakage power analysis attacks in FDSOI systems based on the application of a random body bias. The are analyzed and relative difficulty obtain secret key, once taken into account, compared original proposals. A new countermeasure, bias scheme, is then proposed. countermeasure equalization asymmetries static consumption dependent data being stored registers implemented technology. countermeasure’s effectiveness theoretically established through development model technological parameters, further reinforced numerical simulations dummy cryptosystem implementing part an AES encrypting round.
