| Abstract(in English) | Information Centric Networking (ICN) is a promising Internet architecture wherein destinations are specified by data names. Despite usefulness of such name-based communications, there is a risk such that privacy of consumers is leaked from data names. Even if data names are encrypted, attackers reveal data names using frequency attacks under the condition that popularities of data are public. The vulnerability comes from the fact that the single encryption key is used for encrypting all the data names. The paper addresses the vulnerability under the condition that multiple encryption keys are used and considers a mitigation method against frequency attacks. |
