Abstract
An approach is provided for providing secure packetized voice transmissions. A public/private key pair is generated at a call device (or endpoint). An encrypted voice stream is received from another call device, where the encrypted voice stream was encrypted using a public key of the public/private key pair. This encrypted voice stream when received at the call device is decrypted using a private key of the public/private key pair.
Claims20
A method comprising:
- generating, at a call device, a public/private key pair;
- receiving an encrypted voice stream from another call device, wherein the encrypted voice stream being encrypted using a public key of the public/private key pair;
- and
- decrypting, at the call device, the encrypted voice stream using a private key of the public/private key pair.
1 more element
An apparatus comprising:
- a public/private key generator configured to generate a public/private key pair;
- an endpoint configured to receive an encrypted voice stream from another endpoint, wherein the encrypted voice stream being encrypted using a public key of the public/private key pair;
- and
- a decrypter configured to decrypt the encrypted voice stream using a private key of the public/private key pair.
1 more element
A method comprising:
- receiving, a public key warehouse, a first request for a first public key from a first call device, wherein the first public key was generated as part of a first public/private key pair by the first call device;
- receiving, at the public key warehouse, a second request for a second public key from a second call device, wherein the first call device has initiated a secure telephony session with the second call device;
- and
- transmitting the second public key to the first call device and the first public key to the second call device for use in encrypting voice traffic associated with the secure telephony session.
