Secure and reliable communication is one of the most important issues in the public safety domain. For public safety and emergency response organizations such as the Police and Fire departments, reliability and security of their communications is fundamental and requires both authentication of users as well as encryption of voice and data communication. Project 25 (P25) public safety waveform is the waveform of choice for most public safety and emergency response organizations in Northern America and includes features to enhance reliability and security of communications. This thesis describes the design and implementation of an encryption framework for a P25 waveform in a Software Communication Architecture (SCA) environment on an open-source Software Defined Radio (SDR) platform. The design and implementation of the framework which starts with a high level modeling of its state machine using pseudocode, goes through a bit-true intermediate implementation and ends with the final cycle-true and bit-true platform-specific implementation is discussed. This thesis proposes an encryption framework that is feasible for implementing the P25 encryption specifications and can be rapidly prototyped in an SCA environment on a cheap off-the-shelf SDR platform involving multiple processors.

This thesis reports research undertaken to address the deficiencies that existing standardised cryptographic constructs exhibit when securing packet mode wireless communication in WSN. The aim of the research is to devise innovative cryptographic frameworks, which will facilitate design and implementation of light-weight symmetric cryptographic modular constructs. Four cryptographic frameworks have been devised and block cipher based light-weight constructs using the frameworks have been designed and benchmarked against contemporary standard constructs. The constructs introduced in this dissertation, proved to be better suited to providing secure packet mode data communication, in applications utilising wireless networks consisting of characteristically constrained nodes. The four proposed frameworks are: - The Zone-based framework for data packet integrity and authentication security services is proposed and described. The Quicker Block Chaining (QBC) family of message authentication constructs designed using the framework, are shown, via software simulation, to operate with better efficiency (i.e. uses fewer instruction cycles) than similar contemporary standard constructs and with a comparable level of security. - The Hybrid Encryption Mode (HEM) framework for data packet confidentiality security service is proposed and described. The HEM framework facilitated the design of constructs that provide probabilistic, randomising and tweakable encryption. - The Joint Cypher Mode (JCM) framework for authenticated encryption with associated-data (AEAD) security service is proposed and described. The range of constructs designed using the JCM framework, are shown, via software simulation and practical deployment, to Design and Analysis of Light-weight Symmetric Cryptographic Frameworks and Constructs for Secure Packet Mode Wireless Communication operate with better efficiency (i.e. uses fewer instruction cycles) than contemporary standard constructs. - The Joint Authenticated Combined Mode (JACM) framework for authenticate authenticated-encryption with associated-data (AAEAD) security service is proposed and described. The new AAEAD secure packet paradigm addresses a limitation and cryptographic protection failure of the standardised AEAD secure packet paradigm, in communication scenarios when untrustworthy intermediary forwarding nodes are utilised to authenticate and relay packets. The outcomes of the research undertaken are relevant to practitioners and cryptographic engineers that require symmetric cryptographic light-weight constructs for providing secure packet mode communications. It is shown that the resulting light-weight symmetric cryptographic constructs are better suited to providing secure packet mode wireless networked communication.

The Medical Device Coordination Framework (MDCF) is an open source Medical Application Platform (MAP) that facilitates interoperability between heterogeneous medical devices. The MDCF is designed to be an open test bed for the conceptual architecture described by the Integrated Clinical Environment (ICE) interoperability standard. In contrast to existing medical device connectivity features that only provide data logging and display capabilities, a MAP such as the MDCF also allows medical devices to be controlled by apps. MAPs are predicted to enable many improvements to health care, however they also create new risks to patient safety and privacy that need to be addressed. As a result, MAPs such as the MDCF and other ICE-like systems require the integration of security features. This thesis lays the groundwork for a comprehensive security architecture within the MDCF. Specifically, we address the need for access control, device certification, communication security, and device authentication. We begin by describing a system for ensuring the trustworthiness of medical devices connecting to the MDCF. To demonstrate trustworthiness of a device, we use a chain of cryptographic certificates which uniquely identify that device and may also serve as non- forgeable proof of regulatory approval, safety testing, or compliance testing. Next, we cover the creation and integration of a pluggable, flexible authentication system into the MDCF, and evaluate the performance of proof-of-concept device authentication providers. We also discuss the design and implementation of a communication security system in the MDCF, which enables the creation and use of communication security providers which can provide data confidentiality, integrity, and authenticity. We conclude this work by presenting the requirements and a high level design for a Role-Based Access Control (RBAC) system within the MDCF.

Security is one of the biggest concerns in the developing world. It is important to ensure a safe transfer of information between communicating parties, protecting them from attacks. Many standards and developed encryption protocols are available as resources and are used based on the requirements. In this thesis, we propose a customized encryption algorithm and an authentication scheme to safely transfer information. The algorithm is a variation of Advanced Encryption Standard (AES) and is carried out between multiple devices. AES uses only one private key (symmetric key) to encrypt the data. The implementation works on a single standard irreducible polynomial of degree '8' which is further used to compute multiplicative inverse tables, S-boxes and inverse S-Boxes required for the working of every layer in the algorithm. As compared to AES, we use sixteen irreducible polynomials of degree '8' instead of one in our implementation. Key sizes for AES are usually 128, 192 and 256 bits in size; we use a 128-bit key. Unlike symmetric encryption, asymmetric encryption uses two keys, private and public keys. The public keys are shared among the communicating parties, while the private keys are kept secret. The keys are supposed to be large in size to maintain strength. Thus, they usually range from 512 bits to 2048 bits or more for asymmetric cryptography. The communicating parties can start with public-private keys and agree upon a common key (session key) which can be used as a key to AES. Diffie-Hellman key exchange protocol uses a combination of AES and RSA algorithms resulting in reliable cryptosystems. Our algorithm focuses on devising a new protocol for key establishment and agreement, using the combination framework. The implementation of the communication protocol between two devices, with a prospect of working with multiple devices using a centralized server, is presented. The outcome is to establish a different approach towards encryption and enhance security by providing protection against Man-in-the-Middle attacks. The customized algorithms are implemented using Python.
