Symmetric key cryptography makes use of two types of ciphers: block ciphers and stream ciphers. A block cipher takes a predetermined number of bits, known as a block, in the plaintext message and encrypts that block. Blocks are commonly composed of 64 bits but can be larger or smaller depe...
The massive data generated by the Internet of Things (IoT) is often outsourced to the cloud, leading to a separation between data ownership and management.
Blockchain technology offers a robust framework for integration with the Internet of Things (IoT), enhancing interoperability, security, privacy, and scala
You can skim through this diagram before taking a closer look at the rest of the handbook. It is all about the key activities in this world (whatever you want to call it: blockchain, cryptocurrency or Web3), which consists of three main processes: creating a wallet, backing up a wallet...
A unique symmetric key SKE is randomly generated for the registration procedure by Vm. When the vehicle is registered, during the drive, the VM uses its visual sensor camera installed on OBU to record video files of the road conditions and estimate their message digest. This practice is ...

Today, we’re going to cover these two both groups of symmetric key ciphers. But what is the difference between a stream cipher vs block cipher? What types of ciphers fall under each umbrella? Which ones are used in SSL/TLS encrypted connections? And how do block and stream ciphers work ...
blockchain; Internet of Things; information security; reconstruction diagram1. Introduction With the arrival of the 5G era, the Internet of Things technology has been rapidly developed, the efficiency of information transmission dramatically improved, and people’s access to information gradually ...
Privacy and security measures are integral to blockchain topology, utilizing public key cryptography to secure transactions. Additionally, techniques like confidential transactions (CTs) encrypt transaction amounts, ensuring privacy by concealing the actual transaction values. These methods, alongside other av...
