Post-Quantum Public Key Cryptography for the Internet of Things

Magnusson, Olof, Hurtig, Mats January 2019 (has links)
Recent progress in the field of quantum computers provide radically improved muscles to search and sort in lists, solve systems of equations and prime factorize – virtues that inflict an immediate threat to the most common systems for public key cryptography used in a vast proportion of today’s computer networks. NTRUEncrypt is a lattice-based cryptography system which inhibits quantum computers for breaking the algorithm in polynomial time. The cryptographic algorithm is one of the seventeen that passed the first round in the NIST Post-Quantum standardisation competition which serves an indication that this system is robust against the efforts from a cryptanalysist to compromise its security properties. With the development of a server and client application that is built using Python3 integrated with WolfSSL, the results obtained from the experiment show that the suggested model acquires the capabilities to overcome the quantum computers capacities, providing fast quantum-safe asymmetric encryption algorithm for TLS communication in smart homes. The handshake process with NTRUEncrypt and WolfSSL is proven to be significantly faster comparing to other algorithms tested.

Zabezpečení komunikace a ochrana dat v Internetu věcí / Secure Communication and Data Protection in the Internet of Things

Chadim, Pavel January 2018 (has links)
This Master's thesis „Secure communication and data protection in the internet of things“ is dealing with crypthografy and crypthographic libraries, which are compared with eachother according to supporting algorithm and standard. For comparing therewere used following libraries: openSSL, wolfSSL, nanoSSL and matrixSSL. Practical part of the thesis is focused on testing the productivity of each ciphers and protocols of openSSL and wolfSSL libraries on RaspberryPi 2 device. Further, the thesis shows the design of communication scenario client-server in the Internet of Things (IoT). Simple authentication protocol client-server was implemented and simulated on RaspberryPi 2 device.

Srovnání kryptografických primitiv využívajících eliptických křivek na různých hardwarových platformách / Comparison of cryptographic primitives used in elliptic curve cryptograpny on different hardware platforms

Brychta, Josef January 2018 (has links)
This master thesis deals with the implementation of variants of cryptographic libraries containing primitives for elliptic curves. By creating custom metering charts to compare each implementation. The main task was not only the implementation of libraries but also the design and implementation of test scenarios together with the creation of measurement methods for different libraries and hardware platforms. As a result, a number of experimental tests were conducted on different curves and their parameters so that the results of the work included complex problems of elliptic curves in cryptography. The main parameters were power, time and memory consumption.
