Nurse Education Today   38 138-143   Mar 2016
© 2015 Elsevier Ltd. Background: In Japan, the departments of nursing were established by 2004, and graduate school programs for master's degree were established by 2008, in 42 national universities. With these changes, a more academic mission has...

The password-protected secret sharing (PPSS, for short) and its security notion, called in this paper the PPSS-security, were proposed by Bagherzandi, Jarecki, Saxena and Lu. However, another security notion for PPSS schemes, the pparam-security w...

Proceedings of 2014 International Symposium on Information Theory and Its Applications, ISITA 2014   566-570   Jan 2014
© 2014 IEICE. We propose a password-protected secret sharing scheme which is provably secure without the random oracles. Three tools enable us to achieve this property: the IND-CCA secure threshold encryption scheme of Libert and Yung, the linear ...

Technical report of IEICE. ISEC   111(285) 149-154   Nov 2011
We propose the notion of little knowledgeness in interactive proof systems, as a notion alternative to the zero knowledgeness, which means that no verifier can obtain any advice to extract the prover's secret from the conversation history. We show...

Proceedings - 2017 5th International Symposium on Computing and Networking, CANDAR 2017   23 Apr 2018   
© 2017 IEEE. We have proposed a decentralized Peer-to-Peer (P2P) cloud storage scheme achieving high confidentiality by using a large number of unspecified P2P nodes. There is one crucial problem in the scheme: it is generally difficult to maintai...

Proceedings - International Conference on Advanced Information Networking and Applications, AINA   5 May 2017   
© 2017 IEEE. We propose a new secure online storage scheme based on an open P2P network without a central server. In the proposed scheme, attackers cannot detect target user data in the online storage because the user data is divided into some par...

<p>With the development of the big data and artificial intelligence technologies, it is expected that huge patient medical data will be used for medical progress such as computer-aided detection/diagnosis. However, it is not easy to build a system...
