GSM is the most wide spread mobile communications system in the world. However the security of the GSM voice traffic is not guaranteed especially over the core network. It is highly desirable to have end-to-end secure communications over the GSM voice channel. In order to achieve end-to-end security, speech must be encrypted before it enters the GSM network . ‎‏Project requirements: ‎‏No JB, Do not install APP, No Internet Connection ‎‏Analog Voice Encryption ‎‏Encrypting voice of mobile calls (GSM, CDMA, LTE, APP ... calls) directly.

Hi, analog speech encryption or scrambling is comparatively complex process thn digital encryption. My plan is to read the analog audio signal from microphone (or any other source) in raspberry pi ie converting it to digital domain, doing encryption or decryption and converting back to analog domain and send it back to the microphone pin o the audio connector to fed that to mobile or speaker(decryption end), The system will not be connected to internet or any external source, it will not use any external or internal database and server. there will be only audio in/out in this system. Do you have any requirement about the encryption algorithm. In your budget I can provide basic encryption only Please inbox me for more details.

Hi, so we can use a software that won't be easy to tweak but in the end we can encrypt GSM using the same very strong algorithms used on internet connections
