Abstract

Today, with the continuous advancement of technological developments, autonomous and semi-autonomous vehicles facilitate our operations in many areas such as personal and commercial transportation, agriculture, construction and mining, research and exploration. Among these vehicles are autonomous mobile robots (AMRs), which are frequently preferred in factories. One of the reasons why AMRs are preferred is that there is insufficient manpower in the areas where they are used. Secondly, these robots can eliminate risky situations that can threaten the health of workers. In addition, AMRs have the potential to save manpower. In this study, we aim to provide data security for AMRs using wireless communication technologies by using a hybrid encryption method. The security performance of asymmetric encryption and the fast communication advantages of symmetric encryption make it necessary to use both encryption methods together for AMRs. In the hybrid encryption approach, the asymmetric encryption method ECC (Elliptic Curve Cryptography) and the symmetric encryption method AES (Advanced Encryption Standard) are used together. ECDSA (Elliptic Curve Digital Signature Algorithm), the digital signature method based on the ECC encryption method, was used as a reference. In the AES encryption method, GCM (Galois/Counter Mode) is preferred since verification is performed in addition to encryption. In this study, AMRs, which communicate with each other or with the controller system and act as data senders, were encrypted using ECDSA-AES/GCM hybrid encryption method using Python programming language and their performance was evaluated. In this way, the protection of the confidentiality and integrity of the transmitted data in case of a possible data leakage during wireless communication will be examined. As a result, this proposed method aims to provide an important step in terms of data security for autonomous mobile robots using wireless communication. [ABSTRACT FROM AUTHOR]

Abstract

It is possible that an adversary may attack to conventional key encapsulation mechanism (KEM) and data encapsulation mechanism (DEM) structure, if any weakness exists in these algorithms. In order to prevent such kind of attacks and to make the KEM-DEM structure secure in a very strong sense, we propose a scramble algorithm in which KEM and DEM are combined and permuted, then encrypted with symmetric key driving into one block. In addition, for a long term communication between two nodes, we propose a new scheme Combined KEM-DEM which provides message integrity and sender's identity control via an integrated session key. In this method, each message is encrypted with different symmetric key and whole communication traffic is controlled. Simulations made using RSA with different key lengths (256, 512, and 1024 bits) show that by employing the Combined KEM-DEM scheme, computation times of KEM for the encryption and decryption are reduced by 40% as compared to Tag-KEM/DEM [2] and Fujisaki-Okamoto's KEM-DEM [3] schemes.

Abstract

Bilgi teknolojilerinde veri güvenliği için kullanılan simetrik ve asimetrik algoritmaların kendilerine özgü avantajları ve dezavantajları bulunmaktadır. Avantajlar kullanılarak ortadan kaldırılmaya çalışılan dezavantajlar ortaya hibrit mekanizmanın ortaya çıkmasını sağlamıştır. Hibrit mekanizmalar üzerine yapılan çalışmalar KEM – DEM mimarileri üzerine yoğunlaşmıştır. DEM – Data Encapsulation Mechanism mesajın kendisini şifrelemekte, KEM - KEY Encapsulation Mechanism verinin şifrelendiği anahtarın şifrelenmesi işlemini gerçekleştirerek güvenlik altına almaktadır. Çalışmamızda klasik KEM-DEM yapısından farklı olarak mimari sadece veri ve verinin şifrelendiği anahtar olmaktan çıkarıp mimariye bir de güvenlik paketi eklenmiştir. Güvenlik paketinde doğrulama işlemleri ile ilgili veriler bulunmakta güvenlik paketi de şifrelenerek güvenlik altına alınmıştır. Gerek oturum açma, gerek şifreli iletişim sırasında özellikle anahtarlar olmak üzere kişisel bilgiler önemlidir. Kişisel bilgilerin detaylarını ve şifreleme anahtarlarını akılda tutmak zor olabilir. Bu bilgiler doğrulama ve imzalama işlemleri için kullanılacaktır. Bu nokta düşünülerek bu bilgilerin, güvenliği sağlanmış elektronik sertifikalarda tutulması önerilmiştir. Çalışmada elektronik sertifikaların hukuki karşılığından bahsedilmiş ve mimari içinde kullanım biçimi anlatılmıştır. Ayrıca mimarinin testleri .NET platformunda yazılan uygulamalarla test edilmiş. Asimetrik algoritma (RSA) için mobil platform ile de test gerçekleştirilmiş ve performans testi yapılmıştır. Asymmetric and symmetric algorithms used at information technologies for information security have some advantages and also disadvantages. Hybrid encryption mechanism came up to remove the disadvantages.Most of the studies on hybrid mechanism are about KEM-DEM. DEM – Data Encapsulation Mechanism encrypts data and KEM – Key Encapsulation Mechanism encrypts keys to secure the data. In this study, we offer a new architecture different from KEM-DEM mechanism. Data encryption like DEM, key Encryption like KEM and also data security package are the parts of our mechanism. Data security package consists of the data related to the verification processes. Data security package is also encrypted. Keys and personal information are vital when to login to the system and also in the process of transmission. Details of personal data and the keys can be difficult to keep in mind. These data are going to be used for verification and signing. For that reason, it has been offered for the data to be stored in the secure electronic certificates. We stated the legal status of electronic certificates, and expressed the way of the use in our architecture. Personal information, especially encryption-decryption keys, is need during encrypted communication or login to a system. Details of keys or personal information can be hard to remember. This information is used for signing and verification the user because of that they are needed. For that reason personal information certificates offered to store this information. A software developed in .NET platform to test the architecture, and also an application developed for the test of asymmetric algorithm RSA in mobil devices.
