making air traffic surveillance more reliable a new authentication framework for automatic dependent surveillance broadcast ads b based on online offline identity based signature
Security and Communication Networks, 2015Co-Authors: Joonsang Baek, Youngji Byon, Eman Hableel, Mahmoud AlqutayriAbstract:Automatic dependent surveillance-broadcast is an emerging surveillance technology for the future "e-enabled" Aircrafts, which will make it possible for Aircrafts to share their location data with neighboring Aircrafts, ground controllers, and other interested parties. In order to provide the automatic dependent surveillance-broadcast communications with a high level of accuracy and integrity, a reliable authentication mechanism is required. So far, however, very few cryptographic solutions have been offered to achieve this in the literature. Even existing solutions have faced the following challenges: i the authentication solutions based on regular digital signature require complex management of public-key infrastructureell; and ii signing messages exchanged or broadcast frequently in Aircraft-to-Aircraft and Aircraft-to-ground communication modes can cause a computational bottleneck easily. In order to address these challenges, we take a fresh approach to building up an authentication framework by introducing a new online/offline identity-based signature scheme. Our scheme will resolve the public-key infrastructure management issue by using the identities of Aircrafts as public keys and will achieve a high efficiency through online/offline signature generation.

an authentication framework for automatic dependent surveillance broadcast based on online offline identity based signature
2013 Eighth International Conference on P2P Parallel Grid Cloud and Internet Computing, 2013Co-Authors: Joonsang Baek, Youngji Byon, Eman Hableel, Mahmoud AlqutayriAbstract:Automatic Dependent Surveillance Broadcast (ADS-B) is an emerging Aircraft surveillance technology with which the concept of Internet of Things (IoT) is being realized in air traffic networks. The future "e-enabled" Aircrafts will be equipped with ADS-B devices in order to share precise surveillance and location data among the Aircrafts, ground controllers and, possibly, other third parties. ADS-B is expected to reduce air traffic congestion and mitigate Air Traffic Control (ATC) inefficiencies significantly in shared airspace. In order to provide high accuracy and assurance for the ADS-B communications, a secure and reliable authentication mechanism is required. However, this task is challenging in that 1) using regular digital signatures, which was proposed in the literature as an authentication solution, requires management of complex Public Key Infrastructure (PKI) and 2) generating signatures for messages exchanged frequently in Aircraft-to-Ground (A2G) and Aircraft-to-Aircraft (A2A) communication modes can create a computational bottleneck easily. In this paper, we take a fresh approach to this problem by introducing a new type of online/offline identity-based signature scheme. Our scheme will resolve the PKI management issues and achieve high level of efficiency that makes possible for e-enabled Aircrafts to perform frequent signing generations.

safety assessment of generation iii nuclear power plant buildings subjected to commercial Aircraft crash part i fe model establishment and validations
Nuclear Engineering and Technology, 2020Co-Authors: X Liu, J H Sheng, Q FangAbstract:Abstract Investigations of the commercial Aircraft impact effect on nuclear island infrastructures have been drawing extensive attention, and this paper aims to perform the safety assessment of Generation Ⅲ nuclear power plant (NPP) buildings subjected to typical commercial Aircrafts crash. At present Part I, finite element (FE) models establishment and validations for both the Aircrafts and NPP buildings are performed. (i) Airbus A320 and A380 Aircrafts are selected as the representative medium and large commercial Aircrafts, and the corresponding fine FE models including the skin, beam, fuel and etc. are established. By comparing the numerically derived impact force time-histories with the existing published literatures, the rationality of Aircrafts models is verified. (ii) Fine FE model of the Chinese Zhejiang Sanao NPP buildings is established, including the detailed structures and reinforcing arrangement of both the containment and auxiliary buildings. (iii) By numerically reproducing the existing 1/7.5 scaled Aircraft model impact tests on steel plate reinforced concrete (SC) panels and assessing the impact process and velocity time-history of Aircraft model, as well as the damage and the maximum deflection of SC panels, the applicability of the existing three concrete constitutive models (i.e., K&C, Winfrith and CSC) are evaluated and the superiority of Winfrith model for SC panels under deformable missile impact is verified. The present work can provide beneficial reference for the integral Aircraft crash analyses and structural damage assessment in the following two parts of this paper.

safety assessment of generation iii nuclear power plant buildings subjected to commercial Aircraft crash part ii structural damage and vibrations
Nuclear Engineering and Technology, 2020Co-Authors: X Liu, Z F Dong, Q FangAbstract:Abstract Investigations of the commercial Aircraft impact effect on nuclear island infrastructures have been drawing extensive attention, and this paper aims to perform the safety assessment of Generation III nuclear power plant (NPP) buildings subjected to typical commercial Aircrafts crash. At present Part II, based on the verified finite element (FE) models of Aircrafts Airbus A320 and A380, as well as the NPP containment and auxiliary buildings in Part I of this paper, the whole collision process is reproduced numerically by adopting the coupled missile-target interaction approach with the finite element code LS-DYNA. The impact induced damage of NPP plant under four impact locations of containment (cylinder, air intake, conical roof and PCS water tank) and two impact locations of auxiliary buildings (exterior wall and roof of spent fuel pool room) are evaluated. Furthermore, by considering the inner structures in the containment and raft foundation of NPP, the structural vibration analyses are conducted under two impact locations (middle height of cylinder, main control room in the auxiliary buildings). It indicates that, within the discussed scenarios, NPP structures can withstand the impact of both two Aircrafts, while the functionality of internal equipment on higher floors will be affected to some extent under impact induced vibrations, and A380 Aircraft will cause more serious structural damage and vibrations than A320 Aircraft. The present work can provide helpful references to assess the safety of the structures and inner equipment of NPP plant under commercial Aircraft impact.
