A lightweight and secure TFTP protocol for smart environment

Abstract

Internet of Things" (IOT) has become the everyday buzz words in recent years. As part and parcel of the Smart environment where human beings and things interact intelligently, trust and mobility becomes the basic prerequisites. However, to unify trust and mobility, a security protocol must be used for information exchanges among human and things; as well as between things and things (such as between Wi-Fi Client and Wi-Fi AP). In this paper, we present an enhancement of a security protocol for bulk data transfer amongst embedded devices (similar to the practices in IOT). We also proposed a security framework for enhancing security, trust and privacy (STP) for embedded system infrastructure. We suggested the use of lightweight symmetric encryption (for data) and asymmetric encryption (for key exchange) protocols in Trivial File Transfer Protocol (TFTP). The target implementation of TFTP is for embedded devices such as Wi-Fi Access Points (AP) and remote Base Stations (BS). We have chosen Das U-Boot (Universal Boot loader) as the horizontal security platform for this new security implementation which is suitable for Smart Environment.

Security, privacy and trust in Internet of Things: The road ahead

“…To verify this proposal, the authors decided to use UBOOT (Universal 890Boot loader). In[107] two schemes are implied: AES, used to protect personal and sensitive data, and DHKE (Diffie-Hellman Key Exchange), for exchanging cryptographics keys between two entities that do not know each other.In[108] is presented a Naming, Addressing and Profile Server (NAPS) as a middleware to bridge different platforms in IoT environments. Given massive 895 amount of heterogeneous devices deployed across different platforms, NAPS serves as key module at the back-end data center to aid the upstream, the content-based data filtering and matching and the downstream from applications [108].…”

Cryptographic Computation Using ElGamal Algorithm in 32-bit Computing System

“…(2). (2) Similarly, user B will select random number X b independently for Eq. (3) to calculate the public key Y b.: (3) The X values will be kept as private for each side while the Y values are available publicly to the other side.…”

“…The work proposed in this paper aims to improve the overall security, trust and privacy for implementation in boot loader or firmware of embedded devices [2]. This paper focuses on using the Diffie Hellman and ElGamal algorithm since the Key Exchange used is assymmetric as such is more secure than using symmetric key algorithm.…”

“…Diffie-Hellman is the earliest practical implementation of cryptographic key exchange [4]. DHKE is a method that allows two entities to share a secret key over insecure communication channels, although they have no prior knowledge of each other [2].…”

A Trustworthy Mobile Solution for Healthcare Based on Internet of Things

“…The main issues focus on the following aspects: Secure framework and architecture [8,9]; Secure data transmission and communication [10,11]; Privacy preservation [12,13].Yan et al [14] reviews and summaries the existing work as eight taxonomies: Trust Evaluation, Trust [15][16][17] establishes special ecosystem for Health-IoT, and design a trustworthy in-home medication management solution. Yang et al [18] upgrades the solution above and implements a comprehensive intelligent home-based platform for iHome Health-IoT.…”
