Una Arquitectura para la Protección de la Privacidad de las Comunicaciones

Abstract

SHIP6 is an architecture that aims to enable private communications by preventing eavesdroppers from using network or transport level parameters to correlate packets that belong to the same communication. SHIP6 extends the ability of SHIM6 to vary securely the locators used for a communication. The SHIM6 Context Establishment exchange is protected through the negotiation of Diffie-Hellman keys. A mechanism based in pseudo-random sequences is specified to vary the IP address, along with other relevant parameters of the communication such as transport ports, etc., for an ongoing communication. Additionally, a synchronization mechanism that allows unlimited variation for the parameters considered is presented.
