| Abstract(in English) | The recent researches in quantum computing persuade us of the importance of unconditionally secure cryptosystems. Key Predistribution System, which is known to be alternative to Broadcast Encryption, is one of the unconditionally secure cryptosystems, and is attracting much attention in these days. However, no previous research have refered to the necessity of hierarchical structure of Trusted Authority (TA), from the viewpoint of trust transfer. In this article, we discuss the importance of transfer of trust, and show the effective method to construct hierarchical structure of TA. |
