Peter, New capabilities are bing added to offer an Identity Provider (IdP) for our IPDX product using XMPP which will identify devices and authenticate devices and users that are connected to a network. This capability will offer the ability to assure that a device or users is authorized to participate in a network and be able to share information with multiple users, devices, and applications. The following attachment is a white paper on "Protocol Transformation defense against cyber-attack". It has been accepted as the cover story in CONTROL magazine and will be published in the June 2012 issue. See latest updates that now includes Android support: http://www.mact-usa.com. The newest version will also include changes supported in Window 8 and next version of Apple IoS due out next month. Protocol transformation eliminates penetration of viruses and can control read/write access and policy administration on a packet level. This capability prevents certain registers from being accessed or changes without authorization. This capability is inherent in the approach which does not require a VPN. Most significantly the end devices do not have to include virus protection even when accessed via the Internet. All traffic is secured end-to-end using Transport Layer Security (TLS). The following is an article in International Cement Review (ICR) May 2012 entitled "XMPP Revisited": http://www.cemnet.com/Articles/story/149546/xmpp-revisited.html If you have any questions please contact me.
