You might think that built-in GSM security features protect your wireless conversations, but unfortunately this is no longer true. Not only has GSM encryption algorithms already been cracked (see at http://cryptome.org/a51-bsw.htm ), but by operating fake base-stations eavesdroppers can cause cell phones to disable encryption functionality. So, in the absence of authentication, eavesdroppers who operate fake base-stations don't even need to crack the encryption, because there isn't any! Interception of GSM calls is illegal in most, if not all, nations, but equipment to sniff and decode phone calls is readily available. GSM spy gear claims to "auto detect," decode and record conversations and "target specific numbers or randomly screen GSM mobile communication". Moreover, since the export of encryption products to certain countries, such as targets of United Nations sanctions are prohibited. The GSM default version has no encryption in some of the countries since it saves network resources.

In today's dynamic environment you rely on cellular communication to keep in contact with your business and home from all around the world 24 hours a day. Are you worried it's not secure?
LIS Solutions with its OEM manufacturer, has developed the LIScell, a plug-in cellular encryption unit that enable secure point-to-point GSM communications. Use LIScell to regain your peace of mind!
Unlike other existing GSM solutions, which require you to purchase a dedicated and expensive cellular handset, LIScell is an accessory for recently produced popular cell phones and older models such as:
Sony Ericsson: T28, T39, T65, T68, R520, T68i, T200, T226, T230, T238, T300, T310, T312, T316, T610, T616, T618, Z600, T61g, and Z1010 handsets.

Whenever a subscriber wishes to place a secure call from his cellular handset, LIScell will first establish a data session with the recipient, egardless to whom the call was initiated. The LIScell will create a GSM modem session and after successfully synchronized, will establish an agreement key session using Diffie-Hellman algorithm in order to generate a mutual secret AES key that will secure the channel.
The LIScell’s software can be programmed and upgraded factory based, remotely or via a USB connection to PC.
Just attach onto the handset and enjoy military-strength security at EFR voice quality! And the price ... the lowest in the market!!!

LIStrunk to LIScell

In cases where the destination of the call is a client OUTSIDE of the corporate environment, located anywhere in the Public Switched Telephone Network, the LIStrunk maintains the Security by using LISphone or LIScell unit which encrypts/decrypts the call at the destination location. The system compresses voice to 8 Kbit/sec (G-729A) for LISphone and 6.4/5.3Kbit/sec (G723.1) for LIScell while retaining a high voice quality (toll quality) and uses fax relay for fax transmission. The total call setup time is about 6 to 7sec. While the round trip delay is less than 100msec for LISphone and about 400msec for LIScell due to the GSM network constrains.
