This paper examines the application domains of the experimental scripting language Open PROMOL and its processor. The language processor EREBUS is an experimental tool aiming to support developing generic (reusable) components and building domain-specific program generators. Developing of generic VHDL components, data and program specialization for(More)
Program protection, programming code integrity and intellectual property protection are important problems in embedded systems. Security mechanisms for embedded systems have some specific restrictions related to limited resources, bandwidth requirements and security. In this paper we develop a secret encryption key generation algorithm by using the(More)
Bio-cryptography is a progressive technology that combines biometrics with cryptography. The use of biometric data for security purposes has become increasingly popular, but the use of biometric data in cryptography is a new, growing and promising area of research. One of the most important problems of bio generation of a stable encryption key. This pape(More)
This paper introduces the sensor-networked IoT model as a prototype to support the design of Body Area Network (BAN) applications for healthcare. Using the model, we analyze the synergistic effect of the functional requirements (data collection from the human body and transferring it to the top level) and non-functional requirements (trade-offs between(More)
The improved version of the author's previously declared asymmetric cipher protocol based on matrix power function (MPF) is presented. Proposed modification avoids discrete logarithm attack (DLA) which could be applied to the previously declared protocol. This attack allows us to transform the initial system of MPF equations to so-called matrix multivariate(More)
The paper introduces a novel Generative Learning Object (GLO) model, the Stage-Based Model (SBM) to specify the learning content. New capabilities of the model are the content automatic generation and adaptation. Externally, our model has a similar structure as the known two-level generic models (i.e. metadata and content implementation). The internal(More)
