An efficient AES implementation using FPGA with enhanced security features

Abstract: Data transferred in an electronic way is vulnerable to attacks With an aim to protect data for secure communication, a new Hybrid non pipelined Advanced Encryption Standard (AES) algorithm based on traditional AES algorithm with enhanced security features is proposed in this work Abysmal analysis of the AES algorithm implies that the security of AES lies in the S-box operations This paper presents a new approach for generating S-box values (modified S-box) and initial key required for encryption/encryption (improved key generation) using PN Sequence Generator The AES algorithm with proposed modifications shows significant improvement in the encryption quality as compared to traditional AES algorithm The traditional AES algorithm equipped with proposed novel modified S-box technique and improved key generation technique gives an avalanche effect of 60% making it invulnerable to attacks The proposed design is synthesized on various Field Programmable Gate Array (FPGA) devices and compared to the existing designs resulting in significant improvement in throughput The proposed design is implemented on Spartan6 FPGA device

Integration of Smart Phone and IOT for development of smart public transportation system

Abstract: As population is burgeoning, there is an increase in the number of vehicles on the road and hence an upsurge in the problems associated with traffic management, especially the Public Transport. There is also an increase in the number of accidents and various other traffic related issues. Intelligent Transportation System (ITS) provides the solution to most of these problems by integrating existing technologies with the underlying infrastructure. With the advent of mobile technology and the ubiquitous cellular network, real time vehicle tracking for efficient transport management has become viable. The futile long wait for a bus to arrive can be avoided by Intelligent Public Transportation System. The omnipresence of Smart Phones and their ever increasing power at a very economical price makes them one of the most attractive options for developing IOT applications. Here, an approach based on the combination of technologies like GPS and Android is discussed which can assuage passengers who commute by the means of public transport. The user is furnished with explicit information about the current location of nearest buses approaching the bus-stop on a mobile application. Using readily available Android API's, technologies like 3G network and SMS based services in the existing mobile phones can reduce the cost and size of hardware required, as well as lead to a better output.

A survey on IoT applications, security challenges and counter measures

Abstract: Internet of Things (IoT) is a recent technology that permits the users to connect anywhere, anytime, anyplace and to anyone. In this paper, the various medical services of IoT such as Ambient Assisted Living (AAL), Internet of m-health, community healthcare, indirect emergency healthcare and embedded gateway configuration are surveyed. Further, the applications of IoT in sensing the glucose level, ECG monitoring, blood pressure monitoring, wheelchair management, medication management and rehabilitation system are analyzed. The analysis results show that the use of IoT in the medical field increases the quality of life, user experience, patient outcomes and real-time disease management. The introduction of medical IoT is not without security challenges. Hence, the security threats such as confidentiality, authentication, privacy, access control, trust, and policy enforcement are analyzed. The presence of these threats affect the performance of IoT, thus, the cryptographic algorithms like Advanced Encryption Standard (AES), Data Encryption Standard (DES) and Rivest-Shamir-Adleman (RSA) are used. The investigation on these techniques proves that the RSA provides better security than the AES and DES algorithms.

Conducting polyaniline nanocomposite-based paints for corrosion protection of steel

Abstract: The incorporation of inorganic fillers of different nature and size into conducting polyaniline (PANI)-based paint formulation extends the possibility of developing protective coatings with a self-healing capability and improved corrosion protection performance. The resulting PANI-based coatings are characterized as nanocomposite systems if the filler has nano-size dimensions. Nanofillers such as metal and metal oxide nanoparticles, clay, carbon nanotubes, graphene, and other inorganic pigments combined with PANI give rise to a variety of PANI nanocomposites with interesting properties and potential applications. The present review article concerns applications of PANI nanocomposites in steel anticorrosion technology. The advantages of PANI nanocomposite coatings over the parent polyaniline coating are highlighted. The synergistic effect of PANI and nanofiller leads to enhancement of the mechanical, physical, and chemical properties of coatings allowing the self-healing property of PANI to appear through either the anodic protection mechanism resulting in the oxide repairing at pinholes or the controlled inhibitor release mechanism by which the PANI-based nanocomposite coating liberates corrosion inhibitors (dopant ions) on demand upon the generation of a defect on the coating leading to the oxidation of the metal and hence to the reduction of PANI.
