 note = {application/pdf, Since  the  problem  of  disclosing  personal information  on  the  Internet  continues  to  increase, many  anonymous communication  systems  have  been studied. Such systems usually use directory servers to manage the public keys of participant nodes and such node  information  as  IP  address,  port  number,  and NodeID. However, this reduces anonymity because the query  messages  for  the  directory  servers  can  give adversaries  route  information  of  anonymous communication  channels.  To  solve  this  problem, applying ID-Based Encryption has been proposed, but in  the  existing method,  directory  servers  continue  to exist. Our  novel  method,  which  can  grasp  assigned NodeIDs without directory servers, can be applied to existing  Distributed  Hash  Table  (DHT)-based anonymous  communication  systems.  Our  proposal enhances  scalability.  This  paper  describes  the structure of our proposed system and its application.},
