With the assistance of an authentication server, a gateway-oriented password-authenticated key exchange(GPAKE) protocol can establish a common session key shared between a client and a gateway. Unfortunately, a GPAKE protocol becomes totally insecure if an adversary can compromise the authentication server and steal the passwords of the clients. In order to provide resilience against adversaries who can hack into the authentication server, we propose a threshold GPAKE protocol and then present its security proof in the standard model based on the hardness of the decisional Diffie-Hellman(DDH) problem. In our proposal,the password is shared among n authentication servers and is secure unless the adversary corrupts more than t + 1 servers. Our protocol requires n > 3t servers to work. Compared with existing threshold PAKE protocols,our protocol maintains both stronger security and greater efficiency.

The IP-based networks on aircraft serve to support Intemet services via satellites. However, in aeronautical satellite hybrid networks, the TCP protocol performance often deteriorates due to improper decreases and slow recovery of the congestion window. This paper proposes a window size determination and notification mechanism, onboard-gateway-based mechanism （OGBM）, which is based on the onboard gateway in the networks on aircraft. A cross-layer approach is adopted by the onboard gateway to obtain the satellite link bandwidth information. And then, by the gateway, through changing the receiver＇s advertised window field in ACK packets, TCP sources are notified of the window size of each TCP source calculated on the ground of bandwidth delay product and flow numbers. The mechanism is able to avoid improper changes of TCP window and serve multiple users. Simulation results show that the mechanism with the fairness index close to l improves TCP performance in aeronautical satellite networks.

Complex protein interaction networks constitute plant metabolic and signaling systems. Bimolecular fluorescence complementation （BiFC） is a suitable technique to investigate the formation of protein complexes and the localization of protein-protein interactions in planta. However, the generation of large plasmid collections to facilitate the exploration of complex interaction networks is often limited by the need for conventional cloning techniques. Here, we report the implementation of a gateway vector system enabling large-scale combination and investigation of candidate proteins in BiFC studies. We describe a set of 12 gateway-compatible BiFC vectors that efficiently permit the combination of candidate protein pairs with every possible N-or C-terminal sub-fragment of S（CFP）3A or Venus, respectively, and enable the performance of multicolor BiFC （mcBiFC）. We used proteins of the plant molybdenum metabolism, in that more than 20 potentially interacting proteins are assumed to form the cellular molybdenum network, as a case study to establish the functionality of the new vectors. Using these vectors, we report the formation of the molybdopterin synthase complex by interaction of Arabidopsis proteins Cnx6 and Cnx7 detected by BiFC as well as the simultaneous formation of Cnx6/Cnx6 and Cnx6/Cnx7 complexes revealed by mcBiFC. Consequently, these gateway-based BiFC vector systems should significantly facilitate the large-scale investigation of complex regulatory networks in plant cells.
