National Knowledge Network

National Knowledge Network
The NKN is a state-of-the-art multi-gigabit pan-India network for providing a unified high speed network backbone for all knowledge related institutions in the country. The purpose of such a knowledge network goes to the very core of the country's quest for building quality institutions with requisite research facilities and creating a pool of highly trained professionals. The NKN will enable scientists, researchers and students from different backgrounds and diverse geographies to work closely for advancing human development in critical and emerging areas.


NKN Topology




Features:
NKN is designed as a Smart Ultra High Bandwidth network that seamlessly interconnects the leading Scientific and Technological institutions - which are pursuing world-class research and development. NKN design is inherently proactive; it takes into account the requirements that may occur in the near term and long term.
Some of the salient features of the NKN are:
·         Establishing Connectivity for Knowledge and information sharing.
·         Enabling Collaborative Research in emerging areas such as Climate Modeling.
·         Facilitating distance education in specialized fields such as medicine, emerging high tech areas covering info-bio-nano technology.
·         Facilitating an ultra-high speed e-governance backbone for information sharing.




NKN will also act as a test bed for research in the area of network, security and delivery models for various services. As NKN is a new initiative, it will leverage existing initiatives, to ensure faster roll out with modest investment.

Services:
NKN network is designed with the aim of providing:
  • Highest level of availability
  • Robust & reliable connectivity
  • Highest level of Scalability (specifically planned to match the unknown future demands which cannot be envisaged currently)
  • Best Bandwidth Capacity: For NKN, various National Long Distance Carriers (NLDs) have provided 1Gbps / 2.5Gbps capacity links which can be self-healed. Further, the NLDs are in process of upgrading (using DWDM) to 10Gbps or more connectivity.




The main services of NKN can be broadly categorized under the following heads:
  • Generic Services: Internet, Intranet, Network Management Views, e-Mail, Messaging Gateways, Caching Gateways, Domain Name System, Web Hosting, Voice over IP, Multipoint Control Unit (MCU) Services, Video Portals, SMS Gateway, Co- Location Services, Video Streaming etc.
  • Community Services: Shared Storage, e-Mail List Software Application (LISTSERV), Authentication Service, EVO, Session Initiation Protocol (SIP), Collaboration Service, Content Delivery Service, International Collaborations with EU-India Grid, Global Ring Network for Advanced Applications Development (GLORIAD) etc.
  • Special Services: Virtual Private Network Stitching Services [VPN@L2 (Virtual Private Wire Service / Virtual Private LAN Service), VPN@L3] etc.

Flaw in ServerKeyExchange messages of TLS Protocol

Here we will discuss the flaw in the ServerKeyExchange messages of the TLS protocol which caused the Logjam attack over TLS while using Diffie-Hellman Key Exchange. Before SSLv3, we don't use to authenticate the ServerKeyExchange messages where server negotiates with client regarding usage of cipersuite and parameters. From onwards SSLv3, TLS send the signed message where it mention about parameters it will use but remain silent over ciphersuite. Or in other words, signed portion contains parameters but not contain information about ciphersuite the server will going to use. Now just to remind you, the difference between DH and DH-EXPORT is the size of parameters only. So how to use this flaw - If the server supports DH-EXPORT, an attacker (Men-in-the-Middle) can edit the negotiation sent by the client (even if client doesn't support DH-EXPORT), and replace the list of client supported ciphersuite with DH-EXPORT only. The server will in turn send back a

Identity PSK ( iPSK)

With the evolution of IoT (Internet of Things), devices that connect wirelessly have increased many folds. From webcams, Smartwatches, fitness bands, firestick, Alexa, Google Home, and many more.., everything is going wireless for connectivity and so does the security threat. The main concern with IoT devices is the unavailability of the full wireless protocol stack (and in the majority of devices, support of 802.1x is not available). So, previously we only have the WPA-PSK option for connecting the IoT devices.  In WPA*-PSK (WPA or WPA2) WLAN, a Pre-Shared Key (PSK) is configured and distributed to all the clients that connect to the WLAN. This leads to PSK leakage, and it can be accessible to unauthorized users (due to the nature of common PSK across all the devices).  Therefore, there was a need to provision unique PSK or Multiple PSK per SSID. Identity-PSKs are unique pre-shared keys created for clients/groups on the same WLAN. Features of iPSK:-   1.Unique PSK for individual Cli
