This product combines a package of mechanisms which are aimed at preserving of confidentiality during conversations in GSM system. “Rus SIM” is a hardware-software solution developed by Russian and British engineering specialists.
- Number substitution of the caller
This feature prevents your SIM from lowering of encryption level and ignoring the operator or intercept complexes’ commands to switch off the encryption key generation algorithm (A8) stored at a SIM’s module. As a result all your conversations are encoded according to the A5.1. algorithm.
This function allows you to stay invisible for moving intercept complexes. As the work of such complex is based on the replacement of real base station, it (complex) becomes a priority for all phones which are under the coverage area of real base station. Devices protected by our software ignore stations signals of the highest level.
This option lets you change your voice during conversation. Thus it becomes impossible to identify you by phonetic characteristics of the voice. While this process a voice prints transformation takes place.
This function helps to reduce expenses significantly, regardless your location and call direction.
This function allows to hide SIM’s actual number. Your actual authenticator will be unknown for third parties, so that it is impossible to define client’s location.
*In order for this sim card to be secure and work properly, it needs to be in a secure phone.
