Abstract

In a method and system for a communications system, identifying at least one of a received message that has been decrypted using a first decryption method and a message to be sent that is to be encrypted using a first encryption method, generating a copy of the at least one of the received message and the message to be sent, encrypting the copy of the at least one of the received message and the message to be sent using a second encryption method to create an encrypted copy of the at least one of the received message and the message to be sent, and transmitting the encrypted copy of the at least one of the received message and the message to be sent from the communications device for decryption and storage.

transmitting interception software to a communications device upon entry of the communications device into a network.

16. The method for a communication system of claim 1, further comprising:

receiving an encryption key from a communications device.

17. The method for a communication system of claim 1, further comprising:

transmitting an encryption key to a repository.

18. The method for a communication system of claim 1, further comprising:

transmitting the re-encrypted message to a repository using a first communication channel; and

transmitting information on interactions to the repository using a second communication channel.

19. The method for a communication system of claim 1, further comprising:

copying the encrypted message from a memory stack in the communications device.

20. A method for a communication system, comprising:

receiving an encrypted message at a communications device;

decrypting the encrypted message using a first decryption method to create a decrypted message;

re-encrypting the decrypted message using a second encryption method to create a re-encrypted message; and

sending the re-encrypted message for decryption and storage.

21. The method for a communication system of claim 20, further comprising:

decrypting the re-encrypted message to create a decrypted re-encrypted message; and

storing the decrypted re-encrypted message in a repository.

22. The method for a communication system of claim 20, further comprising:

sending information on interactions of the communications device.

23. The method for a communication system of claim 20, further comprising:

receiving interception software on the communications device.

24. The method for a communication system of claim 20, further comprising:
