In recent years, there has been an essential change in the delivery of emergency medicine care, away from traditional healthcare models and towards the adoption of digital technologies, some examples of which include AI, ML and big data18. The variety, speed, and volume of personal health data...
Cryptography, the art of secure communication in the presence of adversaries, has always been a field of dynamic evolution. With advancements in technology, the tools and methods used to break cryptographic algorithms, known as cryptanalysis, have also advanced. This blog post delves into the intric...
Individual blocks contain previous block hash, cryptography hash code, and stored sets of knowledge. The transactions, which happen within the Blockchain are the elemental elements, which transfer data from one IoT node to a different one. The nodes vary in physical composition, though all of ...
Achieving this compiler-like capability, complete with support for Turing-complete computation, marks the advent of what we call programmable cryptography. While this might seem overly optimistic, the reality is nuanced. Bit-wise hash functions, for instance, are not as efficient in a zero-...
The most crucial feature of cryptography is the encryption key, and it is a random string of bits used in combination with an algorithm ( 'a cipher') to transform plain text to cipher text or vice versa. Blockchain makes use of two types of encryption keys:Asymmetric keyandHash function,...
Refer to Figure 7-10. The signature process uses Bob's private key, since he is the only person who has it. The private key is used as the message text is processed through a hash function. A hash is a fixed length value that represents the message content. If the content changes, ...
how capability is used for access control is represented as ICAP = (ID,AR, Rnd) where ID presents the device identifier, AR the set of access rights for the device with device identifier as ID, and Rnd the random number to prevent forgery and it is a result of one-way hash function....

one-way hash function, is used to connect every block on the blockchain. It also assures the block’s compactness, anonymity, and immutability [30]. This leads us to the significance of network nodes. Because the blockchain system is a P2P network, a node may be considered a peer when ...
