“…(C. Arnosti, D. Gruntz and M. Hauri,2015) propose a smartphone based PACS that utilizes the connectivity of the mobile phone to authorize user access requests online by a central access server, while ensuring independence to the PACS from third parties like mobile network operators and handset manufacturers. The paper explores different secure element architectures, such as Host Card Emulation (HCE) and microSD-based secure element (microSD-SE), to achieve this goal (Cambou, 2017).…”

Access control systems are the most utilized preventive and protective solution for guaranteeing highly secure and monitored environments where people can move about and live in complete safety. The Smart Building Access Management System using Digital Keys provides an efficient means of granting or revoking access to users in residential and commercial buildings. It responds to the ever-increasing demand for internet-connected devices and the need for a system that is secure, convenient, and easy to manage. Despite the pivotal role of access control systems, the current technological standing shows severe security vulnerabilities, a lack of practical management solutions and a non-optimized user conveniency. Majorly used credential technologies show an absence of encryption capabilities. Some user management solutions do not scale well and present a lack of proper scalability. Our proposed system in this paper is the Attribute-Based Access Control System (ABACS) for Smart Building Access Management System, which offers an internet-oriented physical access control system, based on an end-to-end secured solution, an easy-to-use hybrid cloud-based system for effective access management and a mobile user application for optimal convenience. Authentication, integrity, and confidentiality are guaranteed using multiple security methods, including a Trusted Execution Environment (TEE) for a safe digital key storage and encryption, and the Transport Layer Security (TLS) protocol for secured channel communication, supported by a trusted third-party Certification Authority (CA). The Near-Field Communication (NFC) channel is used for quick key sharing. Access policies and user management is achieved using the hybrid fog-cloud paradigm and the Attribute-Based Access Control (ABAC) model. Finally, user convenience and optimal user experience are reached by means of an aesthetic mobile application for digital key generation and storage. The testing results and performance evaluation show that our proposed system’s backend, efficiently processes requests in both sequential and concurrent scenarios. With sequential requests, our proposed system’s longest-performing request outperforms iPACS’s by at least tenfold. In addition, with concurrent requests, our system shows a performance at least twice better than iPACS’s.

“…The SRAM based PUFs are not particularly immune to side channel attacks. Significant research efforts have been published regarding the design of PUFs with Flash RAMs [39][40], DRAMs [41][42][43][44], magnetic RAMs [45][46], and resistive RAMs [47][48][49]]. The cryptographic protocols leveraging memory PUFs are in general distinct from the ones developed with other mainstream PUFs such as ring oscillators, or gate delay arbiters.…”

Memory based ternary physical unclonable functions contain cells with fuzzy states that are exploited to create multiple sources of physical randomness, and design true random numbers generators. A XOR compiler enhances the randomness of the binary data streams generated with such components, while a modulo-3 addition enhances the randomness of the native ternary data streams, also generated with the same method. Deviations from perfect randomness of these random numbers, in terms of probability to be non-random, was reported as low as 10-10 in the experimental section of this paper, which is considered as extremely random based on NIST criteria.

“…The international standard ISO7816 specifies the architecture of secure microcontrollers, also called secure elements [41], that are often used to protect smartcards, and IoT peripherals. These devices include a Reduced Instruction Set Computer (RISC) processor; secure, embedded, non-volatile RAM; SRAM; and a crypto-processor.…”

Abstract:Modern computer microarchitectures build on well-established foundations that have encouraged a pattern of computational homogeneity that many cyberattacks depend on. We suggest that balanced ternary logic can be valuable to Internet of Things (IoT) security, authentication of connected vehicles, as well as hardware and software assurance, and have developed a ternary encryption scheme between a computer and smartcard based on public key exchange through non-secure communication channels to demonstrate the value of balanced ternary systems. The concurrent generation of private keys by the computer and the smartcard uses ternary schemes and cryptographic primitives such as ternary physical unclonable functions. While general purpose ternary computers have not succeeded in general use, heterogeneous computing systems with small ternary computing units dedicated to cryptographic functions have the potential to improve information assurance, and may also be designed to execute binary legacy codes.
