Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, a new cache attack against RSA encryption using the time difference of operations, named SWL (SWL: Sliding Windows Leak), was reported.
This attack is applicable to RSA software using the Sliding Window method for modular exponentiation.
By this attack, theoretically, we can reduce the key space up to $10^6$ or less and $2^6$ or less for all the keys of RSA-1024 and, 13% keys of RSA-2048, respectively.
On the other hand, in the same attack, it is not always possible to acquire a complete operation sequence from
SWL, and no concrete method for deriving a fully correct operation sequence from a partially acquired operation sequence is not known in the literature.
In this paper, we present a method to accurately estimate a complete operation sequence from a partial sequence by dividing the acquired operation sequence into short subsequences called "operation pattern."
We also show the effectiveness of the proposed method through experiments using RSA software implemented with common open source software (OSS) of cryptographic operations named Libgcrypt.
