A Novel Security Scheme Based on Instant Encrypted Transmission for Internet of Things

As the most widely applied mobile operating system for smartphones, Android is challenged by fast growing security problems, which are caused by malicious applications. Behaviors of malicious applications have become more and more inconspicuous, which largely increase the difficulties of security detection. This paper provides a new security sandbox approach of Android based on hook mechanism, to further enrich Android malware detection technologies. This new sandbox monitors the behaviors of target application by using a process hook-based dynamic tracking method during its running period. Compared to existing techniques, (1) this approach can create a virtual space where apk can be installed, run, and uninstalled, and it is isolated from the outside and (2) a risk assessment approach based on behavior analysis is given so that users can obtain an explicit risk prognosis for an application to improve their safety. Tests on malware and normal application samples verify this new security sandbox.

“…In their attack, four-byte faults are not under discussion since four-byte faults hardly appear in real attacks. The occurrence rate of the fault type is denoted as , t denotes the number of faulty bytes, and ∈ [1,3]. The notations used are provided in Table 1.…”

“…There are lots of scenarios in IoT where people have to collaborate through devices to complete tasks; for example, a device sends data to other devices [1], or one user shares EHR in mobile cloud computing [2], and these transmitted data are often the privacy data of users. At the same time, in the big data environment [3,4], many enterprises need to constantly assimilate big data knowledge and private knowledge by multiple knowledge transfers to maintain their competitive advantage [5].…”

Towards Optimized DFA Attacks on AES under Multibyte Random Fault Model

Wang

Meng

et al. 2018

Differential Fault Analysis (DFA) is one of the most practical methods to recover the secret keys from real cryptographic devices. In particular, DFA on Advanced Encryption Standard (AES) has been massively researched for many years for both single-byte and multibyte fault model. For AES, the first proposed DFA attack requires 6 pairs of ciphertexts to identify the secret key under multibyte fault model. Until now, the most efficient DFA under multibyte fault model proposed in 2017 can complete most of the attacks within 3 pairs of ciphertexts. However, we note that the attack is not fully optimized since no clear optimization goal was set. In this work, we introduce two optimization goals as the fewest ciphertext pairs and the least computational complexity. For these goals, we manage to figure out the corresponding optimized key recovery strategies, which further increase the efficiency of DFA attacks on AES. A more accurate security assessment of AES can be completed based on our study of DFA attacks on AES. Considering the variations of fault distribution, the improvement to the attack has been analyzed and verified.

“…Since BTC has flourished, Blockchain, the technology that underpins BTC, could, according to Swan, have far-ranging consequences for all aspects of modern society. Based on the characteristics of Blockchain, many researchers have carried out research on its application in the IoT environment [21], such as applying BC to the smart home system to ensure the security and privacy of information [22], applying smart contract in IoT [23], using the BC platform to manage IoT devices [24], and made security transmission for IoT [25]. The reason for this explosion of interest is that, with the Blockchain technology in place, applications that could previously run only through a trusted intermediary can now operate in a decentralized fashion.…”

Blockchain Based Credibility Verification Method for IoT Entities

Zhang

et al. 2018

With the fast development of mobile Internet, Internet of Things (IoT) has been found in many important applications recently. However, it still faces many challenges in security and privacy. Blockchain (BC) technology, which underpins the cryptocurrency Bitcoin, has played an important role in the development of decentralized and data intensive applications running on millions of devices. In this paper, to establish the relationship between IoT and BC for device credibility verification, we propose a framework with layers, intersect, and self-organization Blockchain Structures (BCS). In this new framework, each BCS is organized by Blockchain technology. We describe the credibility verification method and show how it provide the verification. The efficiency and security analysis are also given in this paper, including its response time, storage efficiency, and verification. The conducted experiments have been shown to demonstrate the validity of the proposed method in satisfying the credible requirement achieved by Blockchain technology and certain advantages in storage space and response time.
