发明名称 Method and Apparatus for Generating a Public Key in a Manner That Counters Power Analysis Attacks
摘要 A public key for an Elliptic Curve Cryptosystem is generated in a manner that acts as a countermeasure to power analysis attacks. In particular, a known scalar multiplication method is enhanced by, in one aspect, performing a right shift on the private key. The fixed-sequence window method includes creation and handling of a translated private key. Conveniently, as a result of the right shift, the handling of the translated private key is made easier and more efficient.
