| Abstract(in English) | Countermeasures against the power analysis of cryptographic applications implemented on smart cards are essential. In the case of Elliptic Curve Cryptosystems (ECC), all of the differential power analysis (DPA), the Refined Power Analysis (RPA), and the Zero-value Point Analysis (ZPA) should be considered. Itoh-Izu-Takenaka proposed the Randomized Initial Point countemeasure (RIP) satisfying high security and efficient processing speed in spite of the limitaion that it is applied only to the addition chain from the Least Significant Bit (LSB). Then, Morimoto-Mamiya-Miyaji improved RIP to apply to the addition chain from the Most Significant Bit (MSB) and the window-cased methods. However, these countermeasures are vulnerable to the address-bit DPA (ADPA). This report studies the security of RIP against ADPA, and proposes a countermeasure based on the Randomized Addressing countermeasure (RA) proposed by Itoh-Izu-Takenaka. |
