Available for the following HTC mobile phone models: S740, S521 Snap, Diamond2, HD, HD2, HD mini, Touch Pro2, Touch 3G,  Touch2.

The Secure GSM Crypto Phone developed by Caspertech, designed for the protection of mobile communications, evolved towards an advanced version which encrypts voice and data transmissions over all the following telecommunications networks: GSM, EDGE, GPRS, CDMA, UMTS, HSDPA, 3G, WiFi, and Satellite.

With the brand new crypto phone you can protect your privacy from any kind of interception. The only condition to be able to communicate in a secure manner is that the two partners have a CRYPTECH®.

The protection of the conversation takes place, via an end-to-end encryption, that is to say that everything that is sent from a mobile is encrypted and can only be decoded on the other phone. The whole process takes place in a quick, simple and intuitive way. The bandwidth offered by new mobile networks can provide an excellent quality of voice, equal – if not better – than a normal phone call. The technology of the secure phone allows you to maintain the anonymity of the call, because it is not a phone connection, but an internet connection. Therefore the encrypted mobile call is not explicitly recorded like a call to a phone number, but the connection to a server.

Two encrypted mobile phones connect with each other through a server that only serves as a link. The encryption of the call occurs in the two phones, including a hypothetical attack on the server does not achieve all that other ‘interception of a stream of encrypted data is not intelligible. Caspertech has developed its own VOIP protocol to provide the best performance and a high level of security on the network.

In case a customer has only need of a limited number of phones, the Caspertech server can be used, which will manage the interconnection of users paying a monthly fee. Il score, having instead the need for a network more broadly, with total control of the communication, may be independent of the solution by buying CRYPTECH ® Server, which allows the complete autonomy of management of the network.

The Crypto Phone can also use Wi-Fi connectivity of the office, home or a public hotspot. In this case the connection is completely free. Many operators offer flat rates for internet browsing with the phone and then the encrypted phone calls will be included. The secure GSM phone combines the extreme ease of use, which makes it usable by anyone, all the safety precautions required by the demands of military use, the dual system of management keys, the ability to customize the algorithm, compatible with the Key Management System for the distribution of the keys remotely.

To be able to communicate with another user connected to the same server, the user should only have your number / username in order to ensure their anonymity and preserve their privacy.To provide the best quality, was also designed an audio coding system that continuously adapts to the characteristics of the network you are connected. The system is automatically adjusts the audio encoding type of network (WIFI / UMTS / EDGE / GPRS) whilst ensuring the best quality voice / delay. The transition from a 3G UMTS network to a 2G GPRS / EDGE is handled automatically to eliminate service interruptions of the telephone network.
