As a first step in this process, NIST is looking for comments on its recently published draft minimum acceptability requirements, submission requirements and evaluation criteria for candidate algorithms.
Hashing algorithms are mathematical procedures that take data, usually a message, and chop and combine it down into a much shorter number that is a "fingerprint" of the original data. Good hash algorithms have two features—two different inputs are overwhelmingly likely to generate two different fingerprints, and given a specific fingerprint, there is no practical way of calculating a set of input data that will have the same fingerprint.
Hash algorithms are used widely by the federal government and others in various applications, such as digital signatures and message authentication. FIPS 180-2 specifies five cryptographic hash algorithms—SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512. Because serious attacks have been reported in recent years against cryptographic hash algorithms, including SHA-1, NIST is preparing the groundwork for a more secure hash standard.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
