The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

RSA 1024 Factored in xxx years.

Asked by rdivilbiss in Miscellaneous

Tags: rsa, crack, 1024

One expert says RSA 1024 is safe for thousands of years.  I argue that is Naive, it will be factored much sooner.

When Triple DES was proposed it was said that it would take hundreds of years to break "at what was then current technology."  It has only been a few years and now it can be defeated in a few hours.  In another five years it can be defeated in a few minutes.

Triple DES was cracked in 22 hours: http://www.rsasecurity.com/rsalabs/node.asp?id=2108

RSA has been factored in increasingly sort times.

http://www.rsasecurity.com/rsalabs/node.asp?id=2964 RSA-640 is factored!
http://www.rsasecurity.com/rsalabs/node.asp?id=2879 RSA-200 is factored!
http://www.rsasecurity.com/rsalabs/node.asp?id=2096 RSA-576 is factored!
http://www.rsasecurity.com/rsalabs/node.asp?id=2097 RSA-160 is factored!
http://www.rsasecurity.com/rsalabs/node.asp?id=2098 RSA-155 is factored!
http://www.rsasecurity.com/rsalabs/node.asp?id=2099 RSA-140 is factored!

Note RSA-640 was broken with 30 x86 (2.2 Ghz) processors.

We are not even talking serious hardware here.

Can RSA 1024 be factored in a few years or will it take thousands?
