At CeBIT 2009, Sirrix presents the Sirrix.GSM CryptoGateway, a world novelty in the area of secure voice communication.
Illegal wiretapping poses ever bigger risks to the confidentiality of voice communication, as the respective technical effort has even become less complex with the advent of Voice over IP (VoIP) and GSM networks. Up to now, the market predominantly offered isolated stand-alone products for voice encryption in one single network that required identical, specialized end user devices.
The Sirrix.GSM CryptoGateway combines secure mobile communications with existing land line devices based on VoIP or ISDN technology. The CryptoGateway connects encrypted calls between secure mobile phones and any standard phone set acting as an extension of a private branch exchange within an organisation. This ensures that outsiders are always faced with fully encrypted voice calls while at the same time ensuring that any extension within the organisation can be used to communicate with secure mobile phones. This effectively prevents unsecure connections via the GSM or public fixed telephone network.
The solution has been developed in cooperation with GSMK and is based on their GSMK CryptoPhone® encryption protocol, the leading, FIPS 140-2 certified encryption protocol for trustworthy multi-vendor communications. All of an organisation’s staff that needs to communicate confidential information can be equipped with a GSMK CryptoPhone mobile device for secure communications both mobile to mobile as well as mobile to headquarters back home. Users at headquarters can continue to use their existing standard phone sets (VoIP or ISDN). Moreover, fully encrypted multi-party telephone conferences are possible as well.
The published and fully verifiable CryptoPhone encryption protocol features a 4096-bit Diffie-Hellman key exchange and 256-bit AES and Twofish symmetric session encryption. The Sirrix.GSM CryptoGateway is available immediately from authorized Sirrix distribution partners.
