Blurry Box, a new encryption method to strengthen software protection
 
01:56
https://www.wibu.com/bb Auguste Kerckhoffs postulated his eponymous principle back in the 19th century: "A cryptosystem should be secure even if everything about the system, except for the key, is public knowledge". This means that an effective cryptographic method does not have to be kept secret. If it were, you should wonder why. Wibu-Systems has been true to this principle for several years. Blurry Box cryptography offers software protection that is completely based on publicly available methods and that can thus be assessed and compared. Blurry Box makes it so hard to counterfeit the software that it would be easier and faster to re-develop the application from scratch! http://www.wibu.com/protection-suite/blurry-box-cryptography.html. To test the validity and strength of the newly patented encryption method Blurry Box, now integrated with the anti-debug and obfuscation methods of CodeMeter, Wibu-Systems launched a contest, open to all hackers around the globe. None of the 315 international participants managed to send in a full crack of the encryption scheme. http://www.blurrybox.com.

Institute for Mathematics and its Applications (IMA) Public Lecture Series http://www.ima.umn.edu/public-lecture/ Arnold Family Lecture - Cryptography: Secrets and Lies, Knowledge and Trust 7:00 P.M., Thursday, November 3, 2011, Willey Hall 175 Avi Wigderson (Institute for Advanced Study, Princeton) 1) Did you ever wonder what protects your computer password when you log on, or your credit card number when you shop on-line, from hackers listening on the communication lines? 2) Is it possible for a group of people to play a (cardless) game of Poker on the telephone, without anyone being able to cheat? 3) Can you convince others that you can solve a tough math (or SudoKu) puzzle, without giving them the slightest hint of your solution? 4) Can two people who never met create a secret language in the presence of others, which no one but them can understand? In this talk, I plan to survey some of the mathematical and computational ideas, definitions, and assumptions which underlie privacy and security of the Internet and electronic commerce. I will explain some of the magical consequences of this theory. For example, how the solution of question (1) enables a positive answer to questions (2), (3), and (4). I will also explain the fragility of the current foundations of modern cryptography and the need for stronger ones.

Public Key Cryptography: Secrecy in Public - Professor Raymond Flood
 
01:05:04
For centuries massive intellectual effort has gone into methods of ensuring secure communication, because of its importance in diplomatic, commercial and military affairs. Up until recently these methods have relied on the exchange of a secret key or protocol between correspondents. Now, however, a new approach based on mathematics, called public key cryptography, is used and this underlies much of modern commerce and how you pay over the internet. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/public-key-cryptography-secrecy-in-public Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

But Satoshi believed in this system. He clearly put a lot of time and energy into figuring out how to address problems, at least those that he could foresee, that would inevitably arise. That being sad, in all of the communications that I’ve read between Satoshi and those raising questions about Bitcoin, I’ve never come across instances of overreactions or overly emotional responses. Each question or concern brought up was treated with respect. No political drama or tribalism is to be found and that’s something that I yearn for this crypto space to return to. The quote I’m choosing to highlight this week has to do with a comment posed to Satoshi that addressed the underlying political ramifications that Bitcoin can produce down the line. Satoshi was met this particular comment ending with the line: “You will not find a solution to political problems in cryptography”.Satoshi responded with: “Yes, but we can win a major battle in the arms race and gain a new territory of freedom for several years.” Notice that he didn’t respond in a fit of rage or throw a tantrum like a toddler because this person didn’t think Bitcoin could really change anything in regards to politics. He chose to inspire him with a realistic outcome; by the way, it’s one which we’ve been experiencing for ourselves today. The next time you’re confronted by doubters, or insults, take a page out of Satoshi’s book and elevate the conversation so all parties involved can come away from it at least a little enlightenment.

In this comprehensive 'techtorial' on configuring Site-to-Site IPSec VPNs on Cisco routers with crypto maps we dive into how to secure our data communications. We start with a brief introduction to setting up Site-to-Site VPNs with crypto maps, talk about the use of GRE to support multicast/broadcast for routing protocols, and then discuss the current implementation of point-to-point VPNs using Static Virtual Tunnel Interfaces (SVTI). We go over the semantics of the IKE and ISAKMP Phase 1 and 2 settings, transform sets, tunnel mode vs. transport mode, and end things with a brief discussion of DMVPN and how it fits into the overall architecture of data security. This is all done through the lens of Cisco Networking Academy's CCNA Security v2.0 Packet Tracer activity 8.4.1.2 Enjoy!!!

DEF CON 24 Crypto and Privacy Village - Greg Norcie - My Usability Goes to 11 A Hackers Guide to Use
 
34:27
Tor. PGP. OTR. We have privacy enhancing technologies (PETs), but when was the last time you used privacy software that “just worked’’? Just like security cannot be an afterthought bolted on after the software is written, neither can usability. In this talk, we will discuss why usable PETs are important, why creating usable PETs is challenging, and conclude by describing a real usability evaluation of the Tor Browser Bundle, with a focus on how hackers can perform practical usability evaluations of their own, using tools from the fields of experimental psychology and behavioral economics. BIO: Greg Norcie (Twitter: @gregnorc) is a Staff Technologist at the Center for Democracy and Technology. Before he dropped out of his PhD to move to DC and fight in the crypto wars, Greg was a PhD student doing usable security research at Indiana University, where performed the first peer reviewed lab study of the Tor Browser Bundle’s usability.

Smart Disk Encryption goes beyond standard encryption – shielding every area of your hard drive, including all your system files, and your OS. Even if you remove your HDD, the files will still be encrypted. And if your PC gets into the wrong hands, they won’t even be able to initiate start-up. So whatever brand of laptop you have, take your protection to a new level - install SDE, from Toshiba
