Abstract The electromagnetic radiation of electronic equipment carries information and can cause information leakage, which poses a serious threat to the security system; especially the information leakage caused by encryption or other important equipment will have more serious consequences. In the past decade or so, the attack technology and means for the physical layer have developed rapidly. And system designers have no effective method for this situation to eliminate or defend against threats with an absolute level of security. In recent years, device identification has been developed and improved as a physical-level technology to improve the security of integrated circuit (IC)-based multifactor authentication systems. Device identification tasks (including device identification and verification) are accomplished by monitoring and exploiting the characteristics of the IC’s unintentional electromagnetic radiation, without requiring any modification and process to hardware devices, thereby providing versatility and adapting existing hardware devices. Device identification based on deep residual networks and radio frequency is a technology applicable to the physical layer, which can improve the security of integrated circuit (IC)-based multifactor authentication systems. Device identification tasks (identification and verification) are accomplished by passively monitoring and utilizing the inherent properties of IC unintended RF transmissions without requiring any modifications to the analysis equipment. After the device performs a series of operations, the device is classified and identified using a deep residual neural network. The gradient descent method is used to adjust the network parameters, the batch training method is used to speed up the parameter tuning speed, the parameter regularization is used to improve the generalization, and finally, the Softmax classifier is used for classification. In the end, 28 chips of 4 models can be accurately identified into 4 categories, then the individual chips in each category can be identified, and finally 28 chips can be accurately identified, and the verification accuracy reached 100%. Therefore, the identification of radio frequency equipment based on deep residual network is very suitable as a countermeasure for implementing the device cloning technology and is expected to be related to various security issues.

Exploration Tool

An underground test of a seismoelectric prospecting method for massive sulfides was performed at the Mobrun Mine (Rouyn‐Noranda, Quebec) in June 1991. The method is based upon the conversion of seismic energy to high‐frequency pulses of electromagnetic radiation by sulfide minerals. The delay between shot detonation and detection of the electromagnetic radiation gives a one‐way traveltime for the acoustic wave to reach the zone of seismoelectric conversion, which when combined with P‐wave velocity allows the shot‐to‐ore zone distance to be calculated. A 0.22-kg explosive charge located within 50 m of the orebody provided the seismic excitation, and the resulting electromagnetic emissions were received by electric dipole and induction‐coil antennas. First‐arrival information from a 35‐shot survey above an orebody, the 1100 lens, provides firm evidence that short duration pulses of electromagnetic radiation are produced by the passage of acoustic waves through the orebody. The survey also demonstrated that seismoelectric conversions could be induced at shot‐to‐orebody distances of 50 m and detected at distances of up to 150 m from the orebody. Areas of seismoelectric conversion are highlighted in sections produced by plotting the position of seismic wavefronts during signal reception. The sections show anomalies that correlate with the known structure and location of the orebody and demonstrate the potential of using this seismoelectric phenomenon as an exploration tool.

Purpose The purpose of this study is to examine the operational efficiency of restaurants in a dynamic context, over the period 2011-2014. The paper also analyzes efficiency with respect to several frontiers and production technologies dependent on restaurant size. Finally, it provides a new perspective by examining financial and non-financial variables that can directly affect the efficiency of restaurant firms. Design/methodology/approach The study applies metafrontier data envelopment analysis (DEA) methodology to investigate differences in production technologies, dynamic Tobit regression models and bootstrap procedure. Findings The results reveal that operational efficiency in the restaurant industry is affected by firm size, showing that large restaurants perform better than medium-sized and small restaurants Moreover, the evidence suggests a link between the efficiency index and financial variables, such as credit ratings, probability of default or bankruptcy, leverage and cash flow, as well as a link with non-financial variables, such as type of auditor. Practical implications The strength of restaurant firms has practical implications for managers and entrepreneurs, linked to the investment possibilities and growth potential of companies in that industry. Originality/value This study provides exploratory insights into operational efficiency as well as restaurant efficiency determinants. Performance and operational efficiency are key factors to restaurant firms’ survival in the economies that have been most severely affected by the financial crisis. Furthermore, this study confirms the relevance of financial and non-financial variables, which are associated with firm efficiency in this industry.

Purpose Many scholars have addressed the concept of place-making, yet there is still little formal knowledge about how major societal changes have influenced place-making. The fall of the Berlin Wall in 1989 is an earthshaking event that changed the world, with regard to geopolitics and the internationalisation of our cities and places, thus generating many urban and tourism developments. Therefore, this paper aims to analyse how the term “place-making” has been variously defined and developed as a concept since the time of the fall. Furthermore, it intends to assess whether such analysis can reveal potential competition and synergy for places between tourism and urban developments. Design/methodology/approach To address these two questions, a systematic quantitative literature review of research published between 1991 and 2016 has been used, providing a 25 years overview that reveals the current trends in the research on this topic and highlights the gaps in the existing literature. Findings Findings concerns the variety of definitions, demonstrating the complexity of place-making; four emerging topics (place-making and globalisation; participation; conflicts/challenges; and trendy strategies); and a lack of synergy between tourism and urban development regarding place-making. Research limitations/implications The major limitation to this research is the language criterion, restricted to English, thus automatically eliminating articles written in any other languages. Practical implications This paper can help key stakeholders to re-assess the place-making strategies in light of the findings. Social implications This research demonstrates the emergence of new trends in place-making that need to be addressed to fulfil societal demands and own changes. It can be used as a basis to start reflection and further development for communities and a wide variety of stakeholders. Originality/value The originality of this research resides in the 25-year overview that displays gaps and trends around place-making.

In order to train specialists in information security (IS), a software and hardware complex “Means of protecting information from leakage through technical channels” has been developed; it provides an opportunity to study the process of information leakage through technical channels and methods of its protection, as well as apply various modules and additional software (software) that clearly demonstrate the features of various methods of information security. The composition of this complex is shown: laboratory stands simulating acoustic, vibroacoustic, acoustoelectric channels and a channel of side electromagnetic radiation and interference. At each of the stands there are information security means (ISMs) that prevent the leakage of confidential information through the corresponding technical channel. To adjust the ISMs for acoustic and vibroacoustic channels, the ISIDORA software has been developed; it allows adjusting the level of the generated acoustic interference to meet the requirements of the security of the room and at the same time to have a comfortable conversation in this room.
