EAP-TLS Authentication with an NPS RADIUS Server
EAP-TLS Authentication with an NPS RADIUS Server 802.1X/EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), defined in RFC 5216, provides secure authentication methods. Client devices (RADIUS supplicants) and a RADIUS authentication server verify each other's identity by validating the signature on the computer and server certificates that they send one another. This authentication method uses an infrastructure that includes a RADIUS authentication server that communicates with an external LDAP database. It also needs a mechanism for installing certificates on the server and all the supplicants, which you can do with a Windows NPS (Network Policy Server) using a GPO (Group Policy Object) to distribute computer certificates and an 802.1X SSID client configuration for wireless access. You can also employ the same infrastructure to authenticate users (also referred to as RADIUS supplicants) who submit user names and passwords to the authentication server. This document explains how to set up the following components to provide wireless client and user authentication through 802.1X/EAP-TLS: • (Aerohive) An 802.1X SSID that instructs APs (RADIUS authenticators) to forward authentication requests to an NPS RADIUS server • (Windows) An NPS RADIUS server that accepts authentication requests from the APs and EAP-TLS authentication requests from clients • (Windows) A GPO to deploy computer certificates and a wireless network configuration to clients • (Aerohive and Windows – optional) An Aerohive and NPS configuration in which different RADIUS attributes are returned based on authentication method (EAP-TLS or PEAP-MS-CHAPv2 in this example) assigning one user profile to clients authenticating by certificate and another to users authenticating by user name/password. -
Utility-Grade Core Network Services
WHITEPAPER Utility-Grade Core Network Services The infoblox appliance-based platform integrates distributes, and manages DNS, DHCP, IPAM, TFTP, NTP and more to drive networks and applications Executive Summary Networks and applications have become highly dependent on a collection of essential core network services that are not always “visible” or on the forefront of IT project lists. For example, virtually all applications, including web, e-mail, ERP, CRM, and Microsoft’s Active Directory require the Domain Name System (DNS) for their basic operation. Most IP-based devices, including laptops and desktops, require Dynamic Host Configuration Protocol (DHCP) to obtain an IP address. Newer devices such as IP phones, RFID readers, and cameras that are network-connected require file transfer services (via TFTP or HTTP) to receive configuration information and firmware updates. If core network services are compromised, networks and applications fail. These failures often manifest themselves as “network” or “application” issues but are often caused by failure of the underlying core network services themselves. A majority of enterprises still use an “ad-hoc” collection of disparate systems to deploy core network services and are, therefore, experiencing growing problems with availability, security, audit-ability, and real-time data integration that threaten current and future applications. For more than a decade, the focus of networking professionals has been on physical network architectures with high levels of redundancy and fault-tolerance. From the endpoint inward, enterprise networks are designed to provide high availability with device redundancy and multiple paths among users and data. One of the key components of these architectures has been the network appliance, purpose-built devices that are designed to perform a specific function such as routing, switching, or gateway applications. -

PUF Based Authentication Protocol for Iot
S S symmetry Article PUF Based Authentication Protocol for IoT An Braeken Vrije Universiteit Brussel, Pleinlaan 2, 1050 Brussel, Belgium; [email protected]; Tel.: +32-468-104-767 Received: 11 July 2018; Accepted: 11 August 2018; Published: 20 August 2018 Abstract: Key agreement between two constrained Internet of Things (IoT) devices that have not met each other is an essential feature to provide in order to establish trust among its users. Physical Unclonable Functions (PUFs) on a device represent a low cost primitive exploiting the unique random patterns in the device and have been already applied in a multitude of applications for secure key generation and key agreement in order to avoid an attacker to take over the identity of a tampered device, whose key material has been extracted. This paper shows that the key agreement scheme of a recently proposed PUF based protocol, presented by Chatterjee et al., for Internet of Things (IoT) is vulnerable for man-in-the-middle, impersonation, and replay attacks in the Yao–Dolev security model. We propose an alternative scheme, which is able to solve these issues and can provide in addition a more efficient key agreement and subsequently a communication phase between two IoT devices connected to the same authentication server. The scheme also offers identity based authentication and repudiation, when only using elliptic curve multiplications and additions, instead of the compute intensive pairing operations. Keywords: physical unclonable function; authentication; elliptic curve cryptography; internet of things 1. Introduction Internet of Things (IoT) is experiencing worldwide growth. Not only classical computing and communication devices are connected, but also a whole range of other gadgets that are used in our daily life, such as thermostats, light switches, door locks, refrigerators, etc. -

Diameter-Based Protocol in the IP Multimedia Subsystem
International Journal of Soft Computing and Engineering (IJSCE) ISSN: 2231 – 2307, Volume- 1 Issue- 6, January 2012 Diameter-Based Protocol in the IP Multimedia Subsystem Vinay Kumar.S.B, Manjula N Harihar Abstract— The Diameter protocol was initially developed by II. ROLE OF DIAMETER IN IMS the Internet Engineering Task Force (IETF) as an Authentication, Authorization, and Accounting (AAA) framework The IMS is based on a horizontally layered architecture, intended for applications such as remote network access and IP consisting of three layers, namely, Service Layer, Control mobility. Diameter was further embraced by the Third Generation Layer, and Connectivity Layer. Service Layer comprises Partnership Project (3GPP) as the key protocol for AAA and application and content servers to execute value-added mobility management in 3G networks. The paper discusses the use services for the user. Control layer comprises network control of Diameter in the scope of the IP Multimedia Subsystem (IMS) as servers for managing call or session set-up, modification and specified by 3GPP. This paper presents a solution for the problem release. The most important of these is the Call Session of how to provide authentication, authorization and accounting Control Function (CSCF). Connectivity Layer comprises of (AAA) for multi-domain interacting services by referring open routers and switches, for both the backbone and the access diameter. We have studied the case of ‘FoneFreez’, a service that provides interaction between different basic services, like network telephony and television. The involvement of several parties like A.

When trying to prove the security of a protocol, one usually analyzes the protocol in isolation, i.e., in a network with no other proto- cols. But in reality, there will be many protocols operating on the same network, maybe even sharing data including keys, and an intruder may use messages of one protocol to break another. We call that a multi- protocol attack.
