When both of them are lattice-based methods and Dilithium is so much faster — And, so, NIST selected Dilithium for quantum robust digital signatures. But, they are also taking forward FALCON and SPHINCS+. While SPHINCS+ is a hash-based signature method, FALCON is a lattice method such as Dilithium. Why did NIST pick two lattice methods? Well, first we will analyse why Dilithium was selected…

For the first time in my life, I drive an automatic car. It changes gear for me and puts the brake on when I stop. It’s great, but I worry. With a handbrake, I knew I had almost complete control of the car. But, now, I sit in the car…

What are Merkle trees? Ralph Merkle introduced the concept of Merkle trees in 1988 to create digital signatures and footprints. A Merkle tree can be described as a hash tree with leaf nodes consisting of cryptographic hashing of data blocks. …

Originally published at https://dewapost.com by Dewapost Team on 3 June 2023. In today’s digital era, ensuring data security has become a top priority for individuals and businesses. Encryption plays a crucial role in transforming data into an unreadable form, effectively safeguarding it from unauthorised access. In this beginner’s guide, we…

Naive approach to Big Primes Numbers — Primes, primes, primes… these rare numbers are something between funny and slippery; so interesting and ridiculous difficult to find! You know that prime numbers have been something that cautivated almost any matematician since the acient greek days. And still do!! It’s been proven by Euclid in the acient greek times…

Introduction In recent years, the world has witnessed the emergence and exponential growth of Non-Fungible Tokens (NFTs), revolutionizing the art and digital collectibles market. NFTs have gained significant attention, with artists, celebrities, and investors flocking to the space. However, the environmental implications of NFTs have also become a topic of…

Introduction: In recent years, Non-Fungible Tokens (NFTs) have gained significant attention in the world of art, digital collectibles, and blockchain technology. While NFTs have often been associated with high-profile sales and the monetization of digital assets, they also have the potential to serve as a powerful tool for social activism…

Introduction: Blockchain technology has gained significant attention in recent years for its potential to revolutionize various industries. To understand how blockchain works, it is essential to grasp the concept of consensus, which plays a crucial role in maintaining the integrity and security of the blockchain network. In this article, we will…

Because it can! — In cryptography (if you are interested in the subject I highly recommend you follow Prof Bill Buchanan OBE) we use random numbers all the time. As you probably know, we need strong number generators with good sources of entropy to generate high quality random numbers. Would you say that 121212121212…
