Abstract

Various embodiments are described that relate to random noise addition to a communication. A first secure network can employ a first encryption scheme and a second secure network can employ a second encryption scheme. In order to communicate between the first secure network and the second secure network such that the schemes are not decipherable, random noise can be added to a communication designated to transfer from the first secure network to the second secure network.

First claim

What is claimed is:

1. A system, that is part of a first secure network, comprising:
a reception component configured to receive a randomly-modified second secure network-based non-encrypted voice communication by way of a non-encrypted communication channel;
an encryption component configured to encrypt, according to a first network encryption scheme, the randomly-modified second secure network-based non-encrypted voice communication into an encrypted first secure network voice communication; and
a transmission component configured to transmit the encrypted first secure network voice communication along the first secure network,
where the randomly-modified second secure network-based non-encrypted voice communication is derived from an encrypted second secure network voice communication from a second secure network,
where the first secure network and the second secure network are distinct networks,
where the encrypted second secure network voice communication is encrypted in accordance with a second network encryption scheme, and
where the first network encryption scheme and the second network encryption scheme are different encryption schemes.

2. The system of claim 1 ,
where the randomly-modified second secure network-based non-encrypted voice communication is a second secure network-based non-encrypted voice communication modified by addition of random noise that is not at a human audible level.

3. The system of claim 1 ,
where the encrypted first secure network voice communication is a first encrypted first secure network voice communication,
where the reception component is configure to receive a randomly-modified third secure network-based non-encrypted voice communication from the non-encrypted communication channel,
where the encryption component is configured to encrypt, according to the first network encryption scheme, the randomly-modified third secure network-based non-encrypted voice communication into a second encrypted first secure network voice communication,
where the transmission component is configured to transmit the second encrypted first secure network voice communication along the first secure network,
where the randomly-modified third secure network-based non-encrypted voice communication is derived from an encrypted third secure network voice communication from a third secure network,
where the first secure network and the third secure network are distinct networks,
where the second secure network and the third secure network are distinct networks,
where the encrypted third secure network voice communication is encrypted in accordance with a third network encryption scheme,
where the first network encryption scheme and the second network encryption scheme are different encryption schemes.

4. The system of claim 3 ,
where the randomly-modified second secure network-based non-encrypted voice communication is received from a single noise addition component that adds random noise to the second secure network-based non-encrypted voice communication and
where the random noise-added third secure network-based non-encrypted voice communication is received from the single noise addition component that adds random noise to the third secure network-based non-encrypted voice communication.

5. The system of claim 3 ,
where the randomly-modified second secure network-based non-encrypted voice communication is received from a first noise addition component that adds random noise to the second secure network-based non-encrypted voice communication,
where the randomly-modified third secure network-based non-encrypted voice communication is received from a second noise addition component that adds random noise to the third secure network-based non-encrypted voice communication, and
where the first noise addition component and the second noise addition component are separate and distinct components.

6. The system of claim 1 , comprising:
a collection component configured to collect an encrypted first secure network voice communication with an intended destination of a second secure network;
a decryption component configured to decrypt the encrypted first secure network voice communication into a decrypted first secure network voice communication; and
a transfer component configured to transfer the decrypted first secure network voice communication to a noise addition component where random noise is added and after the random noise is added the decrypted first secure network voice communication is transferred to the second secure network.

7. The system of claim 6 ,
where the non-encrypted communication channel is a hardwire channel,
where the transmission component is configured to transmit the encrypted first secure network voice communication along the first secure network wirelessly, and
where the transfer component is configured to transfer the decrypted first secure network voice communication to the noise addition component by way of the non-encrypted communication channel.

8. The system of claim 1 , comprising:
a check component configured to perform a check on if a source of the randomly-modified second secure network-based non-encrypted voice communication has experienced a tampering,
where the encryption component is prevented from encrypting the randomly-modified second secure network-based non-encrypted voice communication if the check has an outcome that the source has experienced the tampering.

9. A non-transitory computer-readable medium, which is part of a first secure network, configured to store processor-executable instructions that when executed by a processor, cause the processor to perform a method, the method comprising:
receiving a randomly-modified second secure network-based non-encrypted voice communication by way of a non-encrypted communication channel;
encrypting, according to a first network encryption scheme, the randomly-modified second secure network-based non-encrypted voice communication into an encrypted first secure network voice communication; and
transmitting the encrypted first secure network voice communication along the first secure network,
where the randomly-modified second secure network-based non-encrypted voice communication is derived from an encrypted second secure network voice communication from a second secure network,
where the first secure network and the second secure network are distinct networks,
where the encrypted second secure network voice communication is encrypted in accordance with a second network encryption scheme, and
where the first network encryption scheme and the second network encryption scheme are different encryption schemes.

10. The non-transitory computer-readable medium of claim 9 ,
where the randomly-modified second secure network-based non-encrypted voice communication is a second secure network-based non-encrypted voice communication modified by addition of random noise that is not at a human audible level.

11. The non-transitory computer-readable medium of claim 9 ,
where the encrypted first secure network voice communication is a first encrypted first secure network voice communication,
where the reception component is configure to receive a randomly-modified third secure network-based non-encrypted voice communication from the non-encrypted communication channel,
where the encryption component is configured to encrypt, according to the first network encryption scheme, the randomly-modified third secure network-based non-encrypted voice communication into a second encrypted first secure network voice communication,
where the transmission component is configured to transmit the second encrypted first secure network voice communication along the first s
