Whit Diffie on Encryption and PKI | Network World

In the 1970s, Whitfield Diffie co-wrote the recipe for one of today's most widely used security algorithms in a paper called "New Directions in Cryptography." The paper was a blueprint of what came to be known the Diffie-Hellman key exchange, a seismic advancement in Public Key Infrastructure (PKI) technology that makes secure online transactions possible. It's part of such popular protocols as the Secure Sockets Layer (SSL) and Secure Shell (SSH).

Cisco pushes ‘network memory’ to alleviate high-speed bottlenecks | Network World

A Cisco engineer has been recognized for his work on scaling router and switch performance with algorithms he developed at a start-up Cisco acquired three years ago.

It’s not true that voice should always have priority over data | Network World

Last time, we continued a discussion of what happens in an MPLS network if defined traffic levels are exceeded so that some packets need to be dropped. In particular, we stated that there is a belief that - to a certain extent - it is better to drop a few voice packets than to deliver it late. The reason behind this phenomenon is that modern packet voice algorithms are designed with the assumption that some packets will be dropped. In fact, the fact that "never is better than late" led to the usage of UDP

Spamming and phishing with pictures and voice | Network World

Last week, Commtouch announced its new defense against image-only spam, a problem that Commtouch has found to be on the increase over the past several months. Complicating the problem is the fact that spammers who send image-only spam can vary their content slightly in an effort to fool conventional anti-spam defenses. Commtouch's Recurrent Pattern Detection technology uses a variety of sophisticated algorithms that can detect image-based spam, including variations in the same message.

802.11w fills wireless security holes | Network World

IEEE 802.11i, the standard behind Wi-Fi Protected Access and WPA 2, patched the holes in the original Wired Equivalent Privacy specification by introducing new cryptographic algorithms to protect data traveling across a wireless network. Now, the 802.11w task group is looking at extending the protection beyond data to management frames, which perform the core operations of a network.

How TLS protocol works | Network World

Part 3 of a six-part article: The RFC 2246 document states the following: “The cryptographic parameters of the session state are produced by the TLS Handshake Protocol, which operates on top of the TLS Record Layer. When a TLS client and server first start communicating, they agree on a protocol version, select cryptographic algorithms, optionally authenticate each other, and use public-key encryption techniques to generate shared secrets.

Anomaly detection is the best way to prevent virus, worm attacks | Network World

Network behavior analysis is one of the most robust and scalable security technologies. At the core of network behavior analysis are anomaly-based algorithms used to identify emerging threats.

New tool eases WAN optimization to small branches | Network World

The benefits of WAN optimization products are clear. Using compression and latency-reduction algorithms, they essentially increase the amount of traffic that can travel across a WAN link. The benefits: organizations don’t have to upgrade their bandwidth, and typically, they get additional monitoring data about application utilization of bandwidth.

Schneier’s Crypto-Gram always informative | Network World

Bruce Schneier, founder and chief technical officer of Counterpane Internet Security, is a celebrated cryptographer and writer about fundamental issues in information assurance. Two of his most famous popular books are _Beyond Fear_ and _Secrets and Lies: Digital Security in a Networked World_. He is also the author of _Applied Cryptography: Protocols, Algorithms, and Source Code in C_. He exemplifies the ideal of an active scientist: a contributor to new knowledge, a clarifier of confusing information and

Security algorithms raise concerns | Network World

Industry experts agree that the future of two widely used security algorithms is fated, but with no clear alternatives in sight, products that rely on them may have to remain 'good enough' for some time.

Deciphering the world of crypto | Network World

It's the computational magic for scrambling data to keep it secret, and in the U.S., the best-known cryptographic algorithms go by names such as Triple-DES and AES. But in other countries, such as South Korea, Russia and Japan, it is SEED, GOST and Camellia that say security, say nothing of specialized cryptos such as CAVE and A5/1.

Algorithmiq Demonstrates Path to Quantum Utility with IBM - insideBIGDATA

Algorithmiq, a scaleup developing quantum algorithms to solve the most complex problems in life sciences, has successfully run one of the largest scale error mitigation experiments to date on IBM’s hardware. This achievement positions them, with IBM, as front runners to reach quantum utility for real world use cases. The experiment was run with Algorithmiq’s proprietary error mitigation algorithms on the IBM Nazca, the 127 qubit Eagle processor, using 50 active qubits x 98 layers of CNOTS and thus a

Ford enlists MIT, Stanford to drive automated cars | Network World

Ford is enlisting top U.S. universities to make self-driving cars a reality, announcing Wednesday that it hopes researchers at the Massachusetts Institute of Technology can come up with advanced algorithms to help vehicles learn where pedestrians and other automobiles will be located.

Black Duck helps businesses comply with encryption regulations | Network World

ExportIP identifies encryption algorithms within software code.

Vulnerable security algorithms raise concerns | Network World

GAITHERSBURG, MD -- Industry experts agree that the future of two widely used security algorithms is fated, but with no clear alternatives in sight products that rely on them may have to remain “good enough” for some time.

New algorithms could keep drones from crashing into people | Network World

Heavy-handed regulation isn't the only answer to a potential crashing drone problem. Algorithms that understand where the population is and route flights accordingly is the way to go, some say.

The FTC is worried about algorithmic transparency, and you should be too | Network World

Don't assume your Facebook friends are ignoring you -- it could simply be the site's algorithms at work

IEEE working on mesh standard | Network World

Today's wireless LAN mesh networks use proprietary algorithms and are typically deployed outdoors. With an IEEE mesh standard implemented by WLAN vendors, it's possible that in the future every wireless LAN would also be able to configure itself as a mesh network, similar in concept to the Internet.

How connected cars will optimize traffic flow | Network World

Algorithms along with ubiquitous automobile data connections will make traffic jams a thing of the past if scientists get the calculations right.

The battle for wireless antennae | Network World

The promise of doubling the throughput and range of wireless LANs could ensure the success of an emerging antenna technology known as Multiple Input Multiple Output. MIMO algorithms in a radio chipset send information out over two or more antennas. The radio signals reflect off objects, creating multiple paths that in conventional radios cause interference and fading. But MIMO uses these paths to carry more information, which is recombined on the receiving side by the MIMO algorithms.
