We use Advanced Encryption Standard (AES), with a key length of 128 bits, to establish a secured session for resource observation. Our proposed scheme uses the lightweight features of Constrained Application Protocol (CoAP) to enable the clients to observe resources residing on the server, in an energy-efficient manner. The real-world objects communicate with each other using the client–server interaction model. It is a payload-based encryption scheme which uses a simple four-way handshake mechanism to verify the identities of the participating objects. In this paper, we propose a lightweight mutual authentication scheme for the real-world physical objects of an IoT environment. Miniature sensor nodes, embedded in these physical objects, limit the support for computationally complex and resource-consuming secured algorithms. There have been a lot of speculations and future forecasts about these physical objects connected with the Internet, however, most of them lack secure features and are vulnerable to a wide range of attacks. This innovative concept enables a physical object to represent itself in the digital world. Leaving anyone who actually cared without a proper conclusion.The Internet of Things (IoT) is a vision that broadens the scope of the Internet by incorporating physical objects to identify themselves to the participating entities.
The story also ends abruptly, with the two main characters getting ready to fight god himself. We don't even know what Tazuna and Koyori's wish is, the two main characters are the only two that don't have obvious goals they want to achieve. What Nimrods and Ziggurats are is left for the viewer to figure out for themselves: along with what Makihara was researching on, or why Nagaoka took Mayumi away from her sister. We know nothing about how HandShaker teams are chosen, the number of HandShaker teams there is, or how these battles even began in the first place. The problem here though, is that all of this unnecessary exposition doesn't inform us on anything about the plot, or at best, leaves things extremely vague. It's fair to say that at least ten minutes out of every episode is exposition going into key concepts and elements in the anime. Which is unbelievably when you take into account all of the exposition that gets thrown at you in this series. Ignoring the fact that the premise has been done to death, there is no proper explanation for any key elements in the story. The story is even more poorly written though, if you can fathom that. You could never tell how Hand Shakers wanted you to feel during any scenes involving the side characters. It certainly doesn't that all the side character's' personality and behaviour is always inconsistent and flips on the dime.
I don't care about Chizuru and Hagate, or Kodama and Hibiki's motives and struggles because the way they look and act doesn't correlate with their goals.Īnd I especially don't care about Makihara's history with Nagaoka because both of those characters are so BORING! I don't care about Lily and Masaru, or Break and Bind's relationship because the nature of their relationship is too bizarre and weird for me to handle. But it just doesn't work, it's not that easy to do. Even though the writers try their damnedest to portray all the side characters as serious and deep, with a lot of struggles in their everyday life.
I can't invest myself in any of these characters, because the archetypes that they all fall under prevent me from taking them seriously in any sense of the word.
