| Research Abstract |
In this research, we developed a novel anonymous communication system Bifrost to improve safety and practicality of low-latency anonymous communication systems with multiple-encryptions and multistage-relay. Bifrost can realize improving anonymity and reducing costs of multiple-encryptions and succeed in improving safety and practicality. Moreover, we proposed a new method applying ID-based encryption to anonymous communication systems and succeeded in removing directory servers from them. Therefore a decline in anonymity and scalability by directory servers is removed and practicality is improved. However we cannot present a novel method revoking anonymity of a sender when it abused anonymity. Our system just uses an existing revoking method.
