Fractal Modulation and Encryption
This thesis explores the applications fractal coding techniques for securing data transmission in digital transmission systems. Fractal coding modulation is used to camouflage transmission in which Random Scaling Fractal Signals are used for simulating background noise. This form of 'data …

Optimizing fully homomorphic encryption
Fully homomorphic encryption (FHE) presents the possibility of removing the need to trust cloud providers with plaintext data. We present two new FHE scheme variants of BGV'12, both of which remove the need for key switching after a ciphertext multiplication, overall halving the runtime of …

Functional Encryption as Mediated Obfuscation
… and generic construction based on functional encryption. If a functional encryption scheme supports decryption functionality F (m, k), then our construction yields a mediated obfuscation of the class of functions {F (m, ·) | m}. In our construction, the interaction between the client and the …

Encryption of Computer Peripheral Devices
… eavesdropping techniques, such as keyloggers. An encryption system was developed that is simple enough to be used in peripherals that do not have large amounts of processing power and memory. A software driver loaded in the operating system of the host computer communicates with a simple 8-bit …

Practical homomorphic encryption implementations & applications
Homomorphic encryption is an exciting technology that enables computations to be performed over encrypted data. While initial constructions were impractical, recent works have enabled eciency necessary for many practical application. In this thesis, we present a new library for homomorphic …

Thresholdizing lattice based encryption schemes
… of threshold multi-key fully homomorphic encryption and predicate encryption. Through multi-key fully homomorphic encryption [MW16] and threshold fully homomorphic encryption, we can construct a low-round multi party computation (MPC) scheme with guaranteed output delivery, assuming honest …

Backdoor encryption policies : a legal dilemma
… online, but it has influenced our way of living. Encryption, a security measure taken to protect network communications, has found itself in the spotlight due to technological developments relating to the use of end-to-end encryption and national security threats. Such developments have led to a …

IoT data encryption algorithm for security
This research project is about encryption simulation for IoT data. It is important to enhance the security system when sending and receiving the IoT data. Some of these data, especially the health information for a particular person is very sensitive. Therefore, there is a need to encrypt and …

Evaluation of somewhat homomorphic encryption schemes
Homomorphic encryption allows one to outsource expensive computation to an untrusted party while keeping data in an encrypted form. While there has been a growing research focus in fully homomorphic encryption schemes, many real-world applications require a scheme to be only "somewhat" homomorphic. …

Practical and Secure Searchable Symmetric Encryption Constructions
Searchable symmetric encryption (SSE) enables secure searching of encrypted databases (i.e., a set of documents) outsourced to an untrusted server. Dynamic SSE (DSSE) extends this to allow secure updates to the encrypted database. However, SSE constructions have a trade-off between security, …

Implementing health information exchange with searchable encryption
… provable security properties. However, since encryption imposes overhead and loss of functionality, we propose a novel cryptographic construction called BlindStorage that enables keyword search capability over encrypted indices. The major contribution of this work is the demonstration how an …

PFHE: partially homomorphic encryption on CNN inference
Fully Homomorphic Encryption (FHE) enables secure computation on encrypted data, but its high computational overhead poses significant challenges for practical deep learning inference. In many application scenarios, high-resolution images may only contain a small portion of sensitive information. …

FIFE : a Framework for Investigating Functional Encryption
In functional encryption, keys are associated with functions, and ciphertexts with messages. Decrypting a message with a key gives the evaluation of the associated function on that message. We look at bounded-collusion functional encryption, where the number of keys for which security is guaranteed …
