Method and system for sending a message through a secure connection
The method and system enable secure forwarding of a message from a first computer to a second computer via an intermediate computer in a telecommunication network. A message is formed in the first computer or in a computer that is served by the first computer, and in the latter case, sending the message to the first computer. In the first computer, a secure message is then formed by giving the message a unique identity and a destination address. The message is sent from the first computer to the intermediate computer after which the destination address and the unique identity are used to find an address to the second computer. The current destination address is substituted with the found address to the second computer, and the unique identity is substituted with another unique identity. Then the message is forwarded to the second computer.
1. A method for secure forwarding of a message in a secure connection via an intermediate computer, comprising:
a first computer and a second computer establishing a secure connection by negotiating and exchanging keys with one another according to a key exchange protocol via the intermediate computer,
the intermediate computer receiving a secure message having a first source address sent to an address of the intermediate computer,
the intermediate computer reading an unique identity from the secure message,
the intermediate computer finding a destination address of the secure message by using the unique identity, and
the intermediate computer sending the secure message in the secure connection to the destination address by using the address of the intermediate computer as a second source address.
2. The method of claim 1 wherein the method further comprises the step providing the secure message as an UDP message.
