SAS-2 – (Simple and Secure password authentication protocol-version 2) was developed by Dr. Akihiro Shimizu, Professor Kochi University of Technology in Japan, now President of T-SS Labs. It provides an impenetrable mutual authentication security mechanism with one of the fastest and smallest algorithms in the world. IPN technology utilizes SAS-2 protocol in its core.
IPN technology enables fastest and ultra-secure mutual authentication without the need of having CA (Certificate of Authentication) and RADIUS servers because the authentication an encryption keys are dynamically renewed on a packet-by-packet basis.
Since, authentication and encryption keys are renewed dynamically for each packet and not transmitted over the network, decrypting IPN based communication by a hacker/cracker is virtually impossible.
(IPN) HIGHLIGHTS:
SAS-2 protocol features:
In IPN’s Wi-Fi implementation or IPN-WLAN, SAS-2 is implemented in lower layer 2 (lower MAC layer) of IEEE802.11 standard.
SAS-2 (Simple and Secure password authentication protocol.v2) is a lightweight one time password mutual authentication protocol.
SAS-2 protocol can be implemented at any layer of the OSI reference model i.e. (in all protocol stacks or applications). The protocol is so compact and lightweight that it can be implemented even in devices that have very low CPU utilization, such as PDAs and wireless handsets (dual mode mobile cell phones).
High Speed authentication & dynamic password renewal
IPN uses propriety one time password authentication and dynamic encryption key generation algorithm (SAS-2: Simple and Secure password authentication protocol ver.2). It enables high speed and secure authentication without having CA and RADIUS servers. Keys for authentication and encryption are renewed dynamically for packet by packet basis and the keys are not exchanged over the network. Therefore decrypting IPN communications by cracker is virtually impossible.

Data scramble & packet management
IPN Data Scramble
Our patented algorithm manages data scrambling (IPN data scramble) processing and shuts down unauthorized access such as phising, forging, unauthorized packet modification, replay attack and DoS attacks.
