Cryptography

Stanford’s gift to aspiring data scientists: Dive into excellence with free online Data Science courses Data science is one of the most popular and lucrative fields in the twenty-first century. It entails collecting, analyzing, and interpreting massive and complicated data sets to solve real-world problems and add value. Application of Data science necessitates a combination of skills and knowledge from multiple disciplines,…

A cryptographic tag developed at MIT uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item’s surface. Credit: Jose-Luis Olivares, MIT. Chip courtesy of the researchersMIT engineers developed a tag that can reveal with near-perfect accuracy whether an item is real or fake. The key is in the glue on the back of the tag.A few years ago, MIT researchers invented a cryptographic ID tag that is several times…

Apple has rolled out an update to iMessage encryption, the likes of which includes post-quantum protections that the company calls the “most significant cryptographic security upgrade” in the messenger’s history. The M3 MacBook Pro: Made Dark for HalloweenIn a blog post published Wednesday, Apple announced the arrival of PQ3, a new encryption protocol designed to seriously upgrade the messenger’s security. Since its launch in 2011, iMessage has offered end-to-end encryption—which is a nice thing to have if you want to…

Revealing the best cryptography programming languages for 2024: Effective data security Data security depends on cryptography, the science of encoding and decoding data. To guarantee the authenticity, secrecy, and integrity of data, it makes use of mathematical ideas and procedures. Cryptography uses several programming languages, each with special benefits. In 2024, the field of cryptography has seen a rise in the use of…

This is a job for LLL: Give it (or its brethren) a basis of a multidimensional lattice, and it’ll spit out a better one. This process is known as lattice basis reduction.What does this all have to do with cryptography? It turns out that the task of breaking a cryptographic system can, in some cases, be recast as another problem: finding a relatively short vector in a lattice. And sometimes, that vector can be plucked from the reduced basis generated by an LLL-style algorithm. This strategy has helped researchers topple…

We know the end of the line is in sight for classical cryptography. All the security encryption that protects our bank accounts, websites, and credit cards today will eventually be broken. That's not just a threat; that's the reality. When Q-Day comes, which is the day quantum computers can break our existing encryption methods, we'll need a replacement for Advanced Encryption Standard (AES), RSA, and Blowfish. That's why the Linux Foundation and others have united behind the Post-Quantum Cryptography Alliance…

Jeffery DelViscio: Quantum and cryptography: those are two words that might strike fear in the minds of the uninitiated. But in February’s issue of Scientific American, we have a story about how they’re colliding—double whammy.Here to walk us through it is Kelsey Houston-Edwards. Kelsey is a mathematician and journalist. She formerly wrote and hosted the online show PBS Infinite Series. And she wrote this story, called “Tomorrow’s Quantum Computers Threaten Today’s Secrets. Here’s How to Protect Them.”Welcome to Science,…

Explore the Top Cryptography Programming Languages to Learn in 2024 Cryptography is the practice and study of techniques for securing data and systems from unauthorized access, manipulation, or disclosure. Cryptography involves the use of mathematical concepts, algorithms, and protocols to encrypt, decrypt, sign, verify, and authenticate data and messages. Cryptography is essential for ensuring the confidentiality, integrity, and authenticity of data and systems in various domains, such as cybersecurity,…

Governments and businesses are not prepared for the havoc quantum computers will sow in cybersecurity by the end of the decade, according to an International Business Machines Corp. executive.  “Is quantum going to really create a cybersecurity Armageddon?” Ana Paula Assis, IBM's general manager of Europe, Middle East and Africa, said on a panel at the World Economic Forum in Davos on Wednesday. “It's going to.” Quantum computers, an emerging technology that vastly accelerates processing power by performing calculations…

Comcast Comcast, alongside several other big corporations, has recently suffered a devastating data breach. According to reports, it’s possible that hackers got their hands on the data of up to 36 million Comcast Xfinity customers, meaning the company’s cable television and internet department. Although the company is pretty tight-lipped about it, the data breach occurred over two months ago. Here’s what we know and what you should do to protect yourself. The hackers were able to access those masses of customer…
