| Abstract(in English) | A new blockwise encryption scheme employing pseudorancom number generator (PRNG) is presented. Assuming security security of PRNG, it provides security both of data confidentiality and integrity. The method is one path scheme so that this if effective particularly this schame is used for a long message. Because of making use of PRNG, performance can be fast in addition to benefits of preprocessing and parallel computation. For these reasons, the maxmum throughput is very high. As an example, we implemented our scheme with PANAMA. In our implementation, encryption and decryption perform at 202Mbps and 207Mbops on an Alpha processor at 600MHz, where the probability of malicious forgery is less than 2^-32 for a 64GByte message. We also estimated hardware implementation. With additional 40Kgate of PRNG, the maxmum throughput can achieve 9.6Gbps. As for smallest implementation, the additional circuit can be implemented with 3K gate. |
