I am interested to develop a secure-voip for android devices
The data stream between two users is encrypted using the AES algorithm (using 256-bit key length), and a new key is generated for each session (call).
The key exchange is made based on the ZRTP protocol (using the ECDH-384 algorithm) which offers protection against Man in The Middle attacks.
The exchange of the keys is made between users mobile terminals, without involving any 3rd party.
Only apply people that has the application READY or has develop it BEFORE.
I dont want to invest time on developping, just need a ready made one to test. Extremely important.
Read the above, else i will NOT reply your bid.
