Detailed Description

This class is used for encrypting and decrypting messages using a public key cryptography and Amnon Ta-Shma, Ron Berman & Amos Fiat algorithm.

Constructor & Destructor Documentation

Encapsulator::Encapsulator (  const ADDRESS &    my_addr,
const AGENT_VECTOR &    agent_vector
) 
 

Encapsulator constructor.

Parameters:
<my_addr> This parameter will initialize the encapsulator with our address
<agent_vector> This parameter is for setting the agent vector pointer
The constructor will initialize all encryption keys. This operation might take a while if the key is long.

Member Function Documentation

RefCountBuffer Encapsulator::Decrypt (  RefCountBuffer    EncMsg,
ADDRESS &    SendTo,
UINT32 &    RetMsgId
) 
 

Message decryption function.

Parameters:
<EncMsg> Encrypted message to be decrypted
<SendTo> This will be filled with the address to forward the message to if its not for us.
<RetMsgId> A unique message ID for replying the message
Returns:
A Decrypted or decapsulated message buffer.
This function will open the buffer recieved by the agent, and decide weather this is a message for us, a reply or just some message we need to forward.

RefCountBuffer Encapsulator::Encrypt (  MESSAGE    Body,
UINT32    DestinationIndx,
ADDRESS &    SendTo
) 
 

Message encryption function.

Parameters:
<Body> The message text.
<DestinationIndx> Destination in agents vector to send the message to.
<SendTo> Return address of where to send the encapsulated message.
Returns:
An encrypted buffer encapsulated with the route selected.
This function will choose a random path between agents to the requested one. The message then will be encapsulated by the vertex public keys with the addresses and packed into the return buffer.

RefCountBuffer Encapsulator::EncryptReply (  MESSAGE    Body,
UINT32    ReplyMsgId,
ADDRESS &    SendTo
) 
 

Reply encryption function.

Parameters:
<Body> Message to be encrypted as a reply
<ReplyMsgId> The message ID we recieved the message with
<SendTo> The address we need to send the returned buffer to
Returns:
An encrypted reply buffer
This function will encrypt the reply message using the unique keys and return a buffer ready to be sent back in the route recieved.
