Shared generation of authenticator systems (or SGA-systems) generalise Simmons' traditional authentication codes when authenticators for source states are produced by collaboration of a group of senders, rather than a single sender. In this paper we study threshold SGA-systems. We derive information-theoretic and combinatorial lower bounds on the probability of success and the size of the key space, and give two key efficient constructions for SGA-systems based on den Boer A-codes and error-correcting codes. We also give a recursive construction method using perfect hash families to construct SGA-systems for large groups.

IEEE 802.16j Multihop relay network is an important research topic, because it can effectively extend coverage. There are some issues requiring deeply thinking in the multihop relay network. One of the major issues is hop-by-hop authentication of relay nodes. Another issue is the selection of centralized or distributed security architecture. In this paper, we study the two schemes for authentication in multihop relay network in order to explicitly make a choice which security architecture can better achieve our goal.

PMIPv6 is a network-based mobility management protocol which extends MIPv6 protocol and reduces the configuration load on mobile node's side. However, security issues are the main obstacle for the proliferation of PMIPv6. Access authentication is the fundamental security needs for mobile node to gain reliable service at the access network. Unfortunately, few access authentication schemes for PMIPv6 are put forward in the last few years. In this paper, we summarize the typical PMIPv6 authentication schemes from the aspect of centralized authentication and distributed authentication, which can give some new idea on the design of novel and efficient authentication schemes for PMIPv6.

Nowadays, wireless Local Area Networks (WLANs) are widely used in various environments, including business, education, government, public and individual. However, because the attacks against WLANs are easier than LAN, the security architectures in WLANs have been discussed frequently in recent years. This paper proposes a new security architecture that enhances the security of the WLANs based on the new IEEE 802.11i standard for large-scale multinational corporations. Furthermore, by adopting distributed authentication servers, it provides a better performance than the traditional architecture with a central authentication server.

This paper proposes a novel lightweight authentication protocol for fast and efficient continuous authentication of constrained Internet of Things (IoT) mesh network devices. An initial static authentication takes place at the beginning of a session, during which the secret is securely shared between two parties. Once the session is established, the continuous authentication scheme generates time-bound tokens using the shared secret, a time-varying component, and a random value. These are used to verify the identity of the connected device in fixed time intervals. These time-bound tokens, which only remain valid for a predetermined time frame and ensure the continuity aspect of the mechanism, can be linked back to the original secret at the server for verification. Therefore, lightweight continuous authentication is achieved using only a few low complexity cryptographic operations, like hash and MAC, without the need to perform costly cryptographic operations. In case of failure, the node is temporarily blocked for an exponential function period of past occurrences of failure. Performance evaluation over a mesh routing protocol shows that our proposal fulfills lightweight and low bandwidth constraining requirements while satisfying the security requirements of an authentication scheme.

Companies analyse large amounts of sensitive data on clusters of machines, using a framework such as Apache Hadoop to handle inter-process communication, and big data analytic tools such as Apache Spark and Apache Flink to analyse the growing amounts of data. Big data analytic tools are mainly tested on performance and reliability. Security and authentication have not been enough considered and they lack behind. The goal of this research is to improve the authentication and security for data analytic tools. Currently, the aforementioned big data analytic tools are using Kerberos for au- thentication. Kerberos has difficulties in providing multi factor authentication. At- tacks on Kerberos can abuse the authentication. To improve the authentication, an analysis of the authentication in Hadoop and the data analytic tools is performed. The research describes the characteristics to gain an overview of the security of Hadoop and the data analytic tools. One characteristic is that the usage of the transport layer security (TLS) for the security of data transportation. TLS usually establishes connections with certificates. Recently, certificates with a short time to live can be automatically handed out. This thesis develops new authentication mechanism using certificates for data analytic tools on clusters of machines, providing advantages over Kerberos. To evaluate the possibility to replace Kerberos, the mechanism is implemented in Spark. As a result, the new implementation provides several improvements. The cer- tificates used for authentication are made valid with a short time to live and are thus less vulnerable to abuse. Further, the authentication mechanism solves new requirements coming from businesses, such as providing multi-factor authentication and scalability. In this research a new authentication mechanism is developed, implemented and evaluated, giving better data protection by providing improved authentication.

In this paper, a hybrid blockchain-based authentication scheme is proposed that provides the mechanism to authenticate the randomly distributed sensor IoTs. These nodes are divided into three types: ordinary nodes, cluster heads and sink nodes. For authentication of these nodes in a Wireless Sensor IoTs (WSIoTs), a hybrid blockchain model is introduced. It consists of both private and public blockchains, which are used to authenticate ordinary nodes and cluster heads, respectively. Moreover, to handle the issue of cluster head failure due to inefficient energy consumption, Improved Heterogeneous Gateway-based Energy-Aware Multi-hop Routing (I-HMGEAR) protocol is proposed in combination with blockchain. It provides a mechanism to efficiently use the overall energy of the network. Besides, the processed data of subnetworks is stored on blockchain that causes the issue of increased monetary cost. To solve this issue, an external platform known as InterPlanetary File System (IPFS) is used, which distributively stores the data on different devices. The simulation results show that our proposed model outperforms existing clustering scheme in terms of network lifetime and data storage cost of the WSIoTs. Our proposed scheme increases the lifetime of the network as compared to existing trust management model, intrusion prevention and multi WSN authentication schemes by 17.5%, 24.2% and 19.6%, respectively.
