EXPERIENCING A NEW INTERNET ARCHITECTURE
Imagining a new Internet architecture enables us to explore new networking concepts without the constraints imposed by the current infrastructure. What are the benefits of a routing protocol that does not rely on global convergence? What about a data plane without inter-domain forwarding tables on routers? What secure systems can we build if a router can derive a symmetric key for any host within 20ns?
In this presentation, we invite you to join us on our 11-year long expedition of creating a next-generation secure Internet architecture: SCION. SCION has already been deployed at several ISPs and domains, and has been in production use for the past 3 years. On our journey, we have found that path-aware networking and multipath communication not only provide security benefits, but also enable higher efficiency for communication, increased network capacity, and even reduce power utilization.

Most previous works relied on time-consuming encryption / authentication algorithms to ensure V2V communication security. This talk focuses on implementation of PHY-layer security via resource allocation. We formulate a secrecy capacity optimization problem, which is solved via decomposing a joint optimization problem into two subproblems: optimal subcarriers and power allocation problems. The subcarriers allocation subproblem is a three-dimensional (3D) search problem. We develop an iterative algorithm, based on which we transform a non-convex power allocation problem to a convex form before solving it using an alternating maximization (AM) algorithm.
Simulation results validate the performance of the proposed resource allocation based PHY-layer security scheme.
