Computing technology is now moving from ubiquitous computing into advanced ubiquitous computing environment. An advanced ubiquitous environment is an extension of ubiquitous environment that improve connectivity between devices. This computing environment has five major characteristics, namely: large number of heterogeneous devices; new communication technology; mobile ad hoc network (MANET); peer-to-peer communication; and Internet of Things. Honeybee computing is a concept based on advanced ubiquitous computing technology to support Smart City-Smart Village (SCSV) initiatives, which is a project initiated within Digital Malaysia. This paper describes the design and implementation of a middleware to support application development within Honeybee computing environment.

Honeybee computing is a concept based on advanced ubiquitous computing technology to support Smart City Smart Village (SCSV) initiatives. Advanced ubiquitous computing is a computing environment that contains many devices. There are two types of communication within Honeybee computing: client server and peer-to-peer. One of the authorization techniques is the OAuth technique, where a user can access an application without creating an account and can be accessed from multiple devices. OAuth is suitable to control the limited access of resources to the server. The server use REST API as web service to publish data from resources. However since Honeybee computing also supports peer-to-peer communication, security problem can still be an issue. In this paper, we want to propose the design of a secure data transmission for Honeybee computing by adopting the authorization process of OAuth 2.0 and Elliptic Curve Diffie-Hellman (ECDH) with HMAC-Sha. This article will also discuss the communication flow after adopting OAuth 2.0 and ECDH to the computing environment.
