Abstract(in English) | Uehara and Safavi-Naini propose a new encryption scheme using arithmetic code. It is consisted of model and Pseudo Random Number Generator (PRNG). The initial parameters of model are part of the secret key to obtain secure against chosen plain text attack. PRNG is to hide the output from the coder. They say that PRNG dose not need to be cryptographically strong and Linear Feedback Shift Register (LFSR) will suffice. In this paper we attack their scheme with a LFSR as PRNG. We derive Attack Equation to determine the initial model by a recurrence relation of LFSR. From the result of attack, we show that their scheme is not secure against known plain text attack if they use a LFSR. |
