Nowdays, the number of IoT Internet of Things devices are growing rapidly around the world with wide range of purposes. Many types of these devices collect data and depending on their purpose, some of the data can be highly sensitive for the user. This calls for security on the device which has to secure the collected data and send it to a server through the Internet. Save to Library. Create Alert.
End-to-end encryption E2EE is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers — including telecom providers , Internet providers , and even the provider of the communication service — from being able to access the cryptographic keys needed to decrypt the conversation. In many messaging systems, including email and many chat networks, messages pass through intermediaries and are stored by a third party,  from which they are retrieved by the recipient. Even if the messages are encrypted, they are only encrypted 'in transit', and are thus accessible by the service provider,  regardless of whether server-side disk encryption is used. Server-side disk encryption simply prevents unauthorized users from viewing this information, it does not prevent the company itself from viewing the information, as they have the key and can simply decrypt this data.
Heterogeneous devices are connected with each other through wireless links within a cyber physical system. These devices undergo resource constraints such as battery, bandwidth, memory and computing power. Moreover, the massive interconnections of these devices result in network latency and reduced speed.
In the past few years, many of the new devices connected to the Internet have not been personal computers, but rather a variety of devices embedded with Internet connectivity and functions. This class of devices has generally been described as the Internet of Things IoT and has brought with it new security and privacy risks. IoT can refer to deployments in homes, businesses, manufacturing facilities, transportation industries, and elsewhere.
Resource-Limited Wireless Device use is growing rapidly. Some of the applications of these devices pose a security threat which can be addressed using cryptographic techniques Kumawat et al. Most of the currently used cryptographic solutions are predicated on the existence of ample processing power and memory.
In cryptography , encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext , into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required.
