Dhwani enables information theoretically secure Near Field Communication (NFC) on existing mobile phones without requiring any special hardware or PKI infrastructure. It uses existing microphones and speakers on phones to perform acoustic NFC. It uses a novel self-jamming based physical layer security technique called SecureJam.https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/dhwani-LogoImage30Percent.png
