In real world applications, knowledge graphs (KG) are widely used in various domains (e.g. medical applications and dialogue agents). However, for fact verification, KGs have not been adequately utilized as a source. can be valuable source verification due to their reliability broad applicability. A KG consists of nodes edges which makes it clear how concepts linked together, allowing machines reason over chains topics. there many challenges understanding these machine-readable map...

Remote attestation (RA) is a process for checking whether device's underlying Trusted Computing Base (TCB) and sensing data from the TCB are trustworthy. In IoT era, RA an important security feature because verifiers make critical decisions based on result. However, massive diverse collection of measurements devices makes managing devices' difficult complex. The cloud blockchain possible candidate addressing problem, but tailored approach essential to support scalable secure management. We...

In-network proactive caching has been considered as an attractive approach for content-centric vehicular networks (CCVNs). The existing strategies cache all data to selected roadside units (RSUs) coming vehicles in order reduce the delay requesting from server. In networks, due high cost of deploying RSUs and their limited storage capacity, they could support only number amount contents decrease hit ratio. To solve problem, we propose a strategy distribute according movement vehicles. With...

Intel Software Guard Extensions (SGX) can address the information disclosure in cloud computing. However, existing virtual machine managers do not provide efficient management operations of SGX-enabled machines (VMs) like live migration. In this paper, we identify challenges and propose a novel approach its implementation model to migrate VMs. As future work, will design protocol new instructions for migration VMs, implement them on top OpenSGX, an open source SGX emulator.

In cloud computing, geographic location of data is one major security concerns users. To resolve this problem, most previous work has been done on trusted relocation service in providers. For example, users are allowed to determine the physical their servers and ensured about requirements relocation-based restrictions. However, it also essential handle at users' devices mobile computing. As tenants use services everywhere, arises a new issue. Thus, paper, we present novel system named...

We present novel system named CAFE for where sensitive logic be executed high secrecy protected any or engineering attempts virtual machine even when...

Even though Internet of things (IoT) sensing services are introduced in a wide range areas, it is not applicable to mission-critical due the lack trustworthiness IoT data. To address this problem, we propose TruSense, novel trusted framework for environment that covers end-to-end implementation from an device cloud service. The TruSense includes small board, communication protocol, and service environment. show our framework's feasibility, design ARM TrustZone-based board implement...

Content-centric vehicular networks (CCVNs) have considered distributed proactive caching as an attractive approach for the timely provision of emerging services. The naïve schemes cache all contents to only one selected roadside unit (RSU) requested vehicles decrease data acquisition delay between source and vehicles. Due high deployment cost RSUs their limited capacity caching, could support a number amount content thus hit ratio. This paper proposes mobility-aware protocol (MDPC) in CCVNs....

Recent success of pre-trained language models (PLMs) has stimulated interest in their ability to understand and work with numbers. Yet, the numerical reasoning over measurements not been formally studied despite importance. In this study, we show that PLMs lack capability required for measurements. Furthermore, find a model trained on measurement-rich corpus shows better performance understanding We propose simple embedding strategy distinguish between numbers units, which leads significant...

Authentication as a Service (AaaS) provides on-demand delivery of multi-factor authentication (MFA). However, current AaaS has left out consideration the trustworthiness user inputs at client evices and risk privacy exposure providers. To solve these concerns, we present TAaaS, Trustworthy Service, which offers trusted path-based MFA service to provider in cloud. TAaaS leverages hypervisor-based path ensure inputs, addresses concerns cloud by storing only irreversible account information. We...

Mobile cloud computing requires the efficient approach to access outsourced data in public clouds due resource scarceness of mobile devices. To this end, should be protected efficiently from being accessed plaintext by unauthorized users and clouds. User revocation appropriately managed guarantee backward secrecy, collusion resistance, key freshness. In paper, we present AKMD (Advanced Attribute-based Key Management for Devices Hybrid Clouds), an improved management hybrid using cipher...

현장원가관리시스템은 회계적 원가와 실제 현장과의 차이를 감소시켜 ‘생산현장을 관리할 수 있는 원가정보의 체계’를 말한다. 본 연구에서는 현장원가관리시스템을 성공적으로 도입한 실제사례를 통해 현장원가관리시스템의 구축 및 설계프로세스를 살펴보았다. A사는 중점 추진과제로 성과관리체계의 개선과 생산프로세스 기준정보의 개선을 선정하였다. 성공적인 정착을 위해서는 생산부문의 성과관리개선 로드맵(road-map)을 수립하고, 실질적인 생산성을 향상시키기 위해 숨겨진 실패원가(failed cost)의 절감이 필요하며, 구축을 위하여 생산현장에 스마트 태그(RFID: radio frequency identification)의 설치가 필수적이라는 것을 사례연구를 확인할 있었다.

본 연구는 회계법인의 감사서비스에 대한 품질을 향상시키기 위해 도입된 품질관리시스템의 구성요소별 특성에 관하여 분석하였다. 품질관리시스템이란 회계법인이 제공하는 감사서비스의 회계법인 내에 구축한 감사인의 업무운영시스템을 말한다. 그런데 품질관리시스템을 구성하는 다양한 요소중 획기적으로 향상시킬 수 있는 요소간의 관계를 분석한 없었다.BR회계법인이 품질은 요소들이 서로 복잡하게 영향을 줄 있으므로 단순히 회계법인내에 구축하고 운영하고 있다는 사실만으로는 설명하기에는 한계가 있다. 따라서 구성요소 중 어떤 항목들이 주어 품질에 미치는지에 연구가 부족한 실정이다.BR 베이지안 네트워크를 활용하여 감사품질관리시스템이 감사품질과 어떠한 연관성이 있는지를 살펴본 연구이다. 즉, 기존의 선행연구에서 많이 다루었던 회귀식의 설명변수(예: 규모, 운영형태 등)와 종속변수(예: 감사시간, 감사품질 등)간의 선형성의 가정을 극복하였다. 구체적으로 감사품질관리시스템의 구성요소인 경영진의 운영책임,...
