The security of message transmission is usually a challenge for its participants. Many available programs that work with audio data claim to enable secured communication, but usually do not show the details of the methods used for data encryption. For end users to be confident, it is essential to be aware of the methods and techniques used for data encryption and decryption. Elliptic curve cryptography, an approach to public key cryptography, is now commonly used in cryptosystems. Hence, in this paper we present a method for using elliptic curve cryptography in order to secure audio data communications. Furthermore, we present a tool that implements this method for encrypting an audio file, transmitting it through the network and decrypting the file at the other end.
Securing a communication is always a challenge for participants in it. A lot of applications available in the market claim to enable secure audio communication, but not always show the details of the technology used behind to encrypt the data. It is important for end users to understand the techniques used for encrypting the data, in order to trust it. Elliptic curve cryptography, an approach to public key cryptography, is now widely used in cryptographic systems. Hence, in this paper we propose using elliptic curve cryptography to secure the transmission of voice messages through the network. The system that is proposed and implemented enables the encryption of the voice message, its transmission through the network and its decryption at the other end.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
