DEATH TO TCP/IP cry Cisco, Intel, US gov and boffins galore

'Named Data Networking' protocol is about the journey, not the destination


The US National Science Foundation, Cisco, Verisign, Panasonic and boffins from around the world have thrown their weight behind a new “Named Data Networking Consortium” that aims to develop “a practically deployable set of protocols replacing TCP/IP that increases network trustworthiness and security, addresses the growing bandwidth requirements of modern content, and simplifies the creation of sophisticated distributed applications.”

The group met for the first time in Los Angeles on Thursday and continue their gabfest on Friday.

UC Los Angeles, UC San Diego, Colorado State University, the University of Arizona, the University of Illinois Urbana–Champaign, the University of Memphis, the University of Michigan and Washington University in St. Louis have all joined the effort. Korea's Anyang University, China's Tongji and Tsinghua Universities, the University of Basel (Switzerland) and Japan's Waseda University are also taking part. Intel, Huawei, Alcatel-Lucent, Qualcomm, Comcast and Orange are also contributing to the effort to create the new protocols.

Work on the Named Data Networking (NDN) has been going on for some time: the National Science Foundation has been pumping in cash since 2010. The significance of this launch is that industry is now involved, and the consortium is committed to producing open-source software to take researchers' work beyond the hypothetical.

Patrick Crowley, an associate professor of computer science & engineering at Washington University's School of Engineering & Applied Science says the group's efforts am to preserve “the balance between sharing information and protecting privacy at the same time.”

“That is very difficult for Internet protocols to handle,” he said, “but something at which NDN excels.” Crowley goes on to explain that NDN will be able to inform users if data on a bank's site was produced and signed by that bank. IP has no way to perform such a verification. NDN will therefore improve internet security.

The consortium says today's internet lacks security because it “ … was designed as a communication network so the only entities that could be named in its packets were communication endpoints.”

Under NDN, the name in a packet “can be anything — an endpoint, a chunk of movie or book, a command to turn on some lights, etc.” By allowing more specific addressing, NDN offers greater control.

The consortium also says its approach won't break the current internet, with the diagram above showing how both offer a “thin waist” allowing communication among many different entities. The consortium hopes to publish “A specification of the standard formats for the two packet types, Interest and Data, in NDN data delivery” so that both simple carriage along the lines of TCP/IP and NDN's more nuanced approach to verifying content's source and connecting entities to content can be achieved.

There's no fixed delivery date for those specs, but the National Science Foundation's cash runs out in 2016. Many of the new commercial members have deep pockets, so it will be no surprise if they kick in some funds to keep the project running until something useful arrives. ®

  • Venezuelan cardiologist charged with designing and selling ransomware
    If his surgery was as bad as his opsec, this chap has caused a lot of trouble

    The US Attorney’s Office has charged a 55-year-old cardiologist with creating and selling ransomware and profiting from revenue-share agreements with criminals who deployed his product.

    A complaint [PDF] filed on May 16th in the US District Court, Eastern District of New York, alleges that Moises Luis Zagala Gonzalez – aka “Nosophoros,” “Aesculapius” and “Nebuchadnezzar” – created a ransomware builder known as “Thanos”, and ransomware named “Jigsaw v. 2”.

    The self-taught coder and qualified cardiologist advertised the ransomware in dark corners of the web, then licensed it ransomware to crooks for either $500 or $800 a month. He also ran an affiliate network that offered the chance to run Thanos to build custom ransomware, in return for a share of profits.

  • China reveals its top five sources of online fraud
    'Brushing' tops the list, as quantity of forbidden content continue to rise

    China’s Ministry of Public Security has revealed the five most prevalent types of fraud perpetrated online or by phone.

    The e-commerce scam known as “brushing” topped the list and accounted for around a third of all internet fraud activity in China. Brushing sees victims lured into making payment for goods that may not be delivered, or are only delivered after buyers are asked to perform several other online tasks that may include downloading dodgy apps and/or establishing e-commerce profiles. Victims can find themselves being asked to pay more than the original price for goods, or denied promised rebates.

    Brushing has also seen e-commerce providers send victims small items they never ordered, using profiles victims did not create or control. Dodgy vendors use that tactic to then write themselves glowing product reviews that increase their visibility on marketplace platforms.

  • Oracle really does owe HPE $3b after Supreme Court snub
    Appeal petition as doomed as the Itanic chips at the heart of decade-long drama

    The US Supreme Court on Monday declined to hear Oracle's appeal to overturn a ruling ordering the IT giant to pay $3 billion in damages for violating a decades-old contract agreement.

    In June 2011, back when HPE had not yet split from HP, the biz sued Oracle for refusing to add Itanium support to its database software. HP alleged Big Red had violated a contract agreement by not doing so, though Oracle claimed it explicitly refused requests to support Intel's Itanium processors at the time.

    A lengthy legal battle ensued. Oracle was ordered to cough up $3 billion in damages in a jury trial, and appealed the decision all the way to the highest judges in America. Now, the Supreme Court has declined its petition.
