Smartcard could leak some power consumption during encryption or signature Differential power analysis (DPA) attackers can analysis encryption key with power information, it brings much more harm than traditional mathematics analysis. RSA is one of the most widely used public key algorithms nowadays. However when it is implemented in embedded devices such as smart cards, it is easy to be threatened by power analysis. In this paper, DPA methods based on algorithmic level of RSA and methods against DPA are studied and we propose a countermeasure of triple masking method against DPA roundly, implemented by simulation, effect is visible.
