Internet

 What IPV6 128 bits address means


The current protocol that the Internet is based on is called IPv4 (Internet protocol version four) and has an address space of 32 bits, or 4 294 967 296 possible addresses that can be assigned to devices that are part of the Internet. That may seem like a lot, but due to the rapid expansion of the Internet (computers, devices like routers and switches) and also of the number of networks that make up the Internet (a network of networks), this is increasingly scarce.


Data security

 The digital signature


The role of the digital signature in emitter/data authentication.

Cryptology and Data Security


The RSA algorithm is one of the most known algorithms used to encrypt texts. The 512 bits RSA key was broken in 1999 by a computer that was the equivalent of 300 PCs averaging 400 MHz and each with at least of 64 Mbytes of RAM.

NIST Issues Call for a New ‘Hash’ Algorithm


The National Institute of Standards and Technology has opened a competition to develop a new cryptographic “hash” algorithm for use in digital signatures, message authentication and other computer security applications.

 World's Smallest Storage Space ... the Nucleus of an Atom


An international team of scientists recently performed the ultimate miniaturization of computer memory: storing information at the nucleus of an atom. The breakthrough is a key step in bringing to life quantum computers, devices based on the theory of quantum mechanics.

 How Secure Is Your Network? NIST Model Knows


Data breaches are a recurring nightmare for IT managers responsible for securing not only their company’s confidential data, but possibly also sensitive information belonging to their clients, such as social security numbers or health or financial records.

 A Computer That Can 'Read' Your Mind


For centuries, the concept of mind readers was strictly the domain of folklore and science fiction. But according to new research published today in the journal Science, scientists are closer to knowing how specific thoughts activate our brains.

‘Combinatorial’ Approach Squashes Software Bugs Faster, Cheaper


A team of computer scientists and mathematicians from the National Institute of Standards and Technology (NIST) and the University of Texas, Arlington is developing an open-source tool that catches programming errors by using an emerging approach called “combinatorial testing.” The NIST-Texas tool, described at a recent conference,* could save software developers significant time and money when it is released next year.

Press F4 to bypass the boot process


You are just minutes from boarding you flight and need to go online to check your email. But it takes three or four minutes for MS Windows to boot-up.

Microsoft owns your computer, now wants to read your mind too


Microsoft says that "Human beings are often poor reporters of their own actions." The solution?

The fastest tool for your homework


NEC launched today SX-9, the word fastest vector supercomputer.

Blood-Cell-Sized Memory Device Beats Industry Estimates for Computing Capacity


Researchers have created an ultra-dense memory device the size of a white blood cell that has enough capacity to store the Declaration of Independence and still have space left over.
