  • WF-IoT - Security techniques for the WSN link layer within military IoT
    2016 IEEE 3rd World Forum on Internet of Things (WF-IoT), 2016
    Co-Authors: Janusz Furtak, Zbigniew Zielinski, Jan Chudzikiewicz
    Abstract:

    Ensuring security in the military applications of IoT is a big challenge. The main reasons for this state of affairs is that the sensor nodes of the network are usually mobile, use wireless links, have a small processing power and have a little energy resources. The paper presents the solution for Cryptographic Protection of transmission between sensor nodes in the data link layer and for Cryptographic Protection of data stored in the sensor node resources. For this purpose, the Trusted Platform Module (TPM) was used. The proposed solution makes it possible to build secure and fault tolerant sensor network. The following aspects were presented in the paper: the model of such a network, applied security solutions, analysis of the security in the network and selected investigation results of such a network were presented.

  • Paper Cryptographic Protection of Removable Media with a USB Interface for Secure Workstation for Special Applications
    2014
    Co-Authors: Jan Chudzikiewicz, Janusz Furtak
    Abstract:

    Abstract—This paper describes one of the essential elements of Secure Workstation for Special Applications (SWSA) to Cryptographic Protection of removable storage devices with USB interface. SWSA is a system designed to process data classified to different security domains in which the multi-level security is used. The described method for protecting data on removable Flash RAM protects data against unau-thorized access in systems processing the data, belonging to different security domains (with different classification levels) in which channel the flow of data must be strictly controlled. Only user authenticated by the SWSA can use the removable medium in the system, and the data stored on such media can be read only by an authorized user by the SWSA. This solution uses both symmetric and asymmetric encryption al-gorithms. The following procedures are presented: creating protected a file (encryption), generating signatures for the file and reading (decryption) the file. Selected elements of the pro-tection systems implementation of removable Flash RAM and the mechanisms used in implementation the Windows have been described. Keywords—filter driver, removable media Protection, symmetric and asymmetric encryption. 1

  • Secure Workstation for Special Applications
    Communications in Computer and Information Science, 2011
    Co-Authors: Adam Kozakiewicz, Zbigniew Zielinski, Janusz Furtak, Anna Felkner, Marek Brudka, Marek Małowidzki
    Abstract:

    The paper presents the recently started project which aims to develop a secure environment for processing of restricted information. The solution being developed by the consortium employs virtualization to allow data from different security domains to be processed on the same physical machine. The system can host Windows and Linux systems as secured guest operating systems. The proposed implementation offers advanced user authentication techniques and Cryptographic Protection. The project is expected to reach technology demonstrator phase in late 2012.

  • ICASSP - Selective Jpeg2000 Encryption of Iris Data: Protecting Sample Data vs. Normalised Texture
    ICASSP 2019 - 2019 IEEE International Conference on Acoustics Speech and Signal Processing (ICASSP), 2019
    Co-Authors: Martin Rieger, Jutta Hämmerle-uhl
    Abstract:

    Biometric system security requires Cryptographic Protection of sample data under certain circumstances. We assess low complexity selective encryption schemes applied to JPEG2000 compressed iris data by conducting iris recognition on the selectively encrypted data. This paper specifically compares the effects of a recently proposed approach, i.e. applying selective encryption to normalised texture data, to encrypting classical sample data. We assess achieved Protection level as well as computational cost of the considered schemes, and particularly highlight the role of segmentation in obtaining surprising results.

  • efficient iris sample data Protection using selective jpeg2000 encryption of normalised texture
    2018 International Workshop on Biometrics and Forensics (IWBF), 2018
    Co-Authors: Martin Rieger, Jutta Hammerleuhl
    Abstract:

    Biometrie system security requires Cryptographic Protection of sample data under certain circumstances. We assess low complexity selective encryption schemes applied to JPEG2000 compressed iris data by conducting iris recognition on the selectively encrypted data. This paper specifically investigates the effect of applying the approach to normalised texture data instead of original sample data in order to further reduce the amount of data to be processed (i.e. compressed and encrypted). Result generalisability is facilitated by the employment of four different iris feature extraction schemes and the systematic consideration of three encryption variants. Depending on the applied iris recognition scheme, Protection equivalent to full encryption can be achieved when encrypting 1/60–1/12 of the data amount of a full iris sample encoded in a JPEG2000 file.
