insight for the enterprise for productivity enhancement, offer unique solutions, and enhance life experience. Technology Trend The Internet has evolved (Figure 2) to become an ever more pervasive and critical infrastructure underpinning society and commerce around the globe. In 1990, with the creation of worldwide web (a method of publishing information on the Internet) by Tim Berners-Lee, Internet became the richest source of information, and since then the number of websites has exploded. Yesterday’s Internet was a universe of interlinked human and creates new generations of interactive experiences. Internet usage had exploded since 1995 to reach the first billion users in 2005. The second billion was in 2010, and the third billion is expected to be reached by the end of 20142. The next phase of the Internet will be IoT: a world of networked smart devices equipped with sensors, connected to the Internet, all sharing information with each other without human intervention. Gartner 26 billion connected devices3 Frost & Sullivan Connected devices amounting to 40 billion connected ‘things’4 IDC 28.11 billion of IoT installed5 CISCO6 & Ericson7 50 billion devices GSMA 25.7billion connected devices; 10.8 billion mobile connected devices8 GSMA 880 million unique subscribers9 UTMS Forum Global mobile subscription reach 9.7 billion10 Table 1 : Usage prediction of IoT Value Propositions With the rise of connected devices and connected individuals, technology experts forecast four interwoven and interaction technology pillars which will fuel and shape the IoT, namely big data, cloud, social media, and mobile devices and things. Big Data With the variety and enormity of data and information collected by the sensors, Big Data technologies will be the cornerstone in extracting meanings and insights of this exponentially increased data, which will enrich the user experiences and enable new business processes and models. Cloud Cloud serves as delivery platform of information and functionality to users. Cloud allows information and knowledge to be accessed and delivered to anyone, anytime and anywhere. Social Social media is transforming interaction and communication modes between individuals in new and unexpected ways. Information will be sourced from physical movement and interactions happening in the Web 2.0. Interconnected societal promote engagements, share information, collaborate and innovate. Mobile devices/things Mobile devices/things are the platforms of social communication and network in both personal and
certificate to confirm the authenticity of the device. Similarly, a digital certificate contains several fields that help to establish and validate the identity of a device or system as it relates to a corresponding public key. certificates will be used to identify devices, sign firmware / software updates, and facilitate encrypted communications. Public Key Infrastructure in Best Practice for IoT The entire identity infrastructure described above is built upon the foundation of public and private keys. It is necessary to make the public keys freely available, but the private keys, however, must be kept secret and secure, or else the credibility of the key in securing an identity is compromised. Figure 3: Security Model for IoT18 The secure generation and storage of these keys is therefore paramount (Figure 3). PKI should be secure by design and ideally implemented in or protected by tamper-resistant hardware. A root of trust effectively creates a barrier between software on the server and cryptographic key material. This approach greatly mitigates the attack vector which seeks to access sensitive cryptographic keys. Protecting Aggregated Big Data with Encryption The sensitivity of data collected, transmitted, and stored as a result of IoT necessitates the use of encryption to secure that data. Encryption plays a vital role in securing data when being passed between devices over the cloud.
