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.

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.

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.

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.

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.

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.

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

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.

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

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

Broadcom Corporation (Nasdaq: BRCM), announced a new single-chip processor that integrates all of the key 3G (third generation) cellular and mobile technologies on an extremely low power, single CMOS...

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.

An introduction to symmetric-key and asymmetric-key encryption algorithms

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.
