Abstract

   This paper describes issues for solutions through cloud inter-
   connection to structural problems, which are called as "silo effects"
   found in cloud-connected electric home appliances, housing equipment
   and sensors in the face of increasingly accelerated connection of
   them.  Specifically, this paper explains an inter-connection
   agreement considered to be required for enhancement of cloud inter-
   connection, what performance guarantee as well as IoT supervising and
   management should be, necessity of inter-connection HUB which is able
   to provide inter-connection amongst the preponderance of private
   cloud groups, and the necessity of a mechanism to avoid threats that
   cause danger to users when we make the inter-connection.

1.  Introduction

   To date, based on the results of interviews with "Things" companies,
   the authors of this paper, the Autors, issued a Problem Statement on
   IoT [1], and reported on an experiment of WebAPI [2].  With further
   interviewing and experiments, various requirements specification on a
   base for securing cloud inter-connection in the anticipated IoT
   society become clearer.

   Currently, the use of various connected devices, hereinafter "IoT
   Devices" is largely expected to become a using scene of IoT, and such
   IoT Device manufacturers operates their private cloud groups, the
   "Cloud", where IoT Devices are connected one after another.  It
   depends on the manufactures whether API of one cloud is open to a
   third party or whether the cloud remains closed just for itself just
   like a "silo".  However, it is expected that API be open by
