Encryption hardware developed for the new technology of computer memory

ScienceDaily (May 18, 2011) security are one of the key obstacles to the adoption of a new non-volatile main memory (NVMM) on the next generation, which improve the computer start and times and increase the memory capacity. But now developed researchers from the University of North Carolina new encryption hardware for use with NVMM to protect your personal information and other data.

NVMM technologies, such as phase-change memory, hold great promise to replace conventional dynamic random access memory (DRAM) in main memory of computers. NVMM will allow computers to begin immediately, and can integrate with more memory and the same amount of space used by existing technologies. However, NVMM is a security risk.

The standard of DRAM main memory stores data after the computer is turned off. That is, for example, that does not store your credit card number and password after the online shopping spree. NVMM, on the other hand, preserves all user data in main memory, and even years after the computer is turned off. This feature may give criminals access to your personal information or other data if your laptop or smart phone were stolen. And, because NVMM the data is stored in main memory, it cannot be encrypted by using the software. Software cannot manage main memory functions, because the software itself is in main memory.

NC State researchers have developed a solution using hardware encryption system called i-NVMM.

"We use hardware to encrypt everything," explains Dr. Yan Solihin, Professor of electrical and computer engineering at NC State and co-author of paper describing i-NVMM, "but then the system will run very slowly – that all the time to encrypt and decrypt data.

"Instead, we developed an algorithm for identifying data is not needed by the processor. This allows us to keep the 78% of main memory are encrypted during normal operation, and slows only system performance on 3.7 percent. "

The i-NVMM also has two additional benefits. First, its algorithm also detects inactivity. This means that people are currently not in use-such as your credit card number--is encrypted automatically. This makes the i-NVMM even more secure than DRAM. Second, while 78 percent of main memory is encrypted when the computer is in use, the remaining 22 percent is encrypted when the computer is turned off.

"Basically, unless someone is accessing your computer when you use it, all data is protected," said Solihin.

I-NVMM relies on the cryptographic engine integrated within the memory module is a stand-alone computer, does not require changes to your computer's processors. This interpretation can be used with different processors and systems.

"We are now looking for partners in the industry who are interested in this technology," said Solihin.

The paper, "i-NVMM: a secure non-volatile memory system key with encryption are cumulative," June 6, International Symposium on computer architecture (ISCA) in San Jose, Calif. paper was surgeon by Dr. Siddhartha Chhabra, ph d student. Former NC State. Research supported, in part, by the National Science Foundation.

Why cannot work with your Web applications

Your idea is (it is):

[] Social Discovery]
[] Cooking [Video]
[] Gaming
[] Music
[] Shopping
[] Business
[] The Technical tool, which gives the peoples lives easier through:

[] Giving them things for free, they were used to pay for.
[] Shows Them interesting things in their surroundings.
[] Enabling them to do things, anywhere, that they have to do at home on your PC.
[] Allows easy access to relevant information about what is on them.
[] Proposing things can do, or that would otherwise make a thought.
[] Proposes new content on the basis of the content, or their friends consume.
[] Giving them a discount when purchasing through your application.
[] Making tasks take minutes, hours.
[] Creates a new way to share things with friends.

It will not work because:

[] Only begins to provide a critical mass of users once it is used.
[] Do not have access to these data.
[] You have solved the problem of "How can I make money from it," but not "Why people need this" problem.
[] You have solved the problem "Why people need it," but not "How can I make money from it" problem.
[] No one is to donate money.
[] No one will pay for something, what they can get for free elsewhere.
[] Have come up with great features, but not a great product.

In Addition:

[There] are already hundreds of people doing similar applications, and your offers a clear difference.
[] Why just Google it yourself instead of buying your company?
[] Don't know enough about the market you're shooting at.
[] You do not have the necessary technical skills personally, nor the techniques in the team.
[] You do not have personal business skills required, neither man commercial team.
You do not have a team, it] you – it hurts me too, one of the founder are statistically more prone to failure:(

However, as long as I'm ticked to total two or fewer fields in the above two parts:

[] You can start on the market, smaller (e.g.: only Great Britain instead of the world, India, the bands instead of all music, Indian cooking, instead of all horror movies instead of each film) and build up here.
[] You can get fast minimum version of the product out to the next month and see how it goes (opportunities multiply as they are seized-as soon as the product which is outside, the new options will be clear).
[] You can attempt to gain investors finance, so you can do business and hire the talent you need.
[] Can be consistently without a business model, the true dotcom bubble style. Maybe you can flip it later, or the business model will arise.

But in the end, don't let me! I started a successful business or failed to start one, instead, I have sinned much worse--is not even trying to seriously. I spend a lot of time spotting, what's wrong with things and ways to improve on them, most of them eventually blog, projects at work or the items in the task list. I'm still waiting for my breakthrough idea hit me, and this post shows the general process to go through to decide if app idea's development. Currently it is the first revision, so I expect I'll be tweaking it, I shall from time to time. Input is greatly appreciated!

Build safety into the computer system that Rashi

ScienceDaily (May 11, 2011) a new publication from the National Institute of standards technology (NIST) provides guidelines to secure the earliest steps of your computer's startup process. Known as the basic input/output system (BIOS), that underlying the system firmware – built-in hardware-computer code initializes the hardware when you switch on your computer before starting the operating system. BIOS security is a new area of focus for the NIST computer security scientists.

"By building security into the firmware, the creation of a secure system," said Andrew Regenscheid, one of the BIOS protection guidelines (NIST Special Publication 800-147). Without appropriate protections, attackers can disable systems or hide malicious software by changing the BIOS. This guide focuses on reducing the risk of unauthorized changes to the bios.

SP 800-115, designed to help manufacturers to write BIOS code provides guidelines for building features into the BIOS to help protect it from being modified or damaged by the attackers. Manufacturers routinely updating system firmware bug fix, patch vulnerabilities, new hardware support. SP 800-115 calls using encryption "digital signatures" in order to verify the BIOS updates before installation based on the current encryption of NIST guidance. The publication is only available as manufacturers begin to deploy the new generation of BIOS. "We believe that manufacturers are ready to implement these guidelines, we hope to see the products soon," said Regenscheid.

The publication also offers recommended that tight management together with the security guidelines for manufacturers. These best practices will help your managers to take advantage of the features of the BIOS when they become available.
