Secfone uses a PEER-TO-PEER CONNECTION for communicating between the devices, there is no such central network device in the system which may be the target of potential eavesdropping attacks. The secure communication is subject to using Secfone devices at all ends of the communication.
 
Beside the highly secure communication, another unquestionable advantage of Secfone is the COST EFFICIENT operation: all calls handled through Secfone are voice over IP (VOIP) based and therefore are invoiced as data traffic instead of voice traffic by your service provider. Secfone calls are handled via the Internet using VOIP, Wi-Fi, HSDPA (3.5G), UMTS (3G) or EDGE (2.5G) networks.
 
55-60 hours of talking on Secfone means cca. 1 Gb data stream.
  
Moreover the device is USER FRIENDLY: it provides outstanding voice quality compared to similar security solutions available on the market we have tested so far; furthermore it provides secure connection and data flow to other VOIP networks using MVCN technology.
 
After the developments made in the last couple of weeks, acting on the market’s demands we managed to find the solution to provide the 100 % safe communication that is completely inaccessible for third persons by delivering „only” the microSD card needed to the MVCN-operation and carrying the private encryption key, and the user can apply it by getting it into his/her own Android-phone.
The microSD card shall install the Secfone-application to the own device automatically, by one click.

The application shall run on the following Android devices:

• Nexus One 2.1, 2.2, 2.3
• HTC Desire 2.1, 2.2
• HTC Liberty 2.2
• HTC Incredible S 2.2
• HTC Hero 2.1
• Motorola Droid 2.1
• Samsung Galaxy S 2.1, 2.2
• Samsung Galaxy Tab 2.2
• Samsung Galaxy S2 2.2
• Samsung Galaxy Mini 2.2
• Toshiba Fujitsu TG-01C2.1
• Huawei S31HW 2.2
• should the Secfone-version newer than 1.3., almost any kind of the Android smart phones

ADVANTAGES OF SECFONE:

• certified encryption procedure
• uses a triple channel encryption protocol: the data channel is encrypted with a 448-bit Blowfish CBC-algorithm which makes the encryption/decryption process fast, while the control (identification) channel uses 2048 bit RSA encryption and the identification of the devices is carried out by 1024 bit RSA encryption;
• encryption procedure is operated by an EAL 4+ certified microSD-card;
• periodic symmetric key change is implemented (in every 5 minutes);
• it provides outstanding voice quality compared to the solutions available on the market we have tested so far
• prevents the possibility of installing any malware, virus or spy programs on the phone by straining off all possible installment attempts of such programs and immediately warning against the danger. The user may install such programs only by manual approval notwithstanding the warnings given by the Secfone-application several times.
