“…Security of ECDL problem lies on its hardness and is deemed as the foundation stone for security of the algorithm. If the attacker is successful in obtaining both n and n × m, he must now determine the value of m which is a challenging task (Chande, Lee, & Li, 2018).…”

With the dawn of mobile banking applications, bank customers can now register for M-banking and download applications that aid them to access services from the bank server remotely from their mobile devices. The conversation between the bank's server and the client application requires a secure connection. However, M-banking is often conducted via unsecure wireless networks on which adversaries can use available techniques to hack into system to steal sensitive financial information including money. This paper's objective is to review the state-of-the-art algorithms that secure data on transit in M-banking. Thus, we document the strengths and weaknesses of these mechanisms and report on structure of their operation. The study reviewed various encryption algorithms such as Rivest-Shamir-Adleman Algorithm, Elliptic Curve Cryptography, Digital Signature Algorithm, Blowfish algorithm, Advanced Encryption Standard, Data Encryption Standard and Tripple Data Encryption Standard. In addition, the study reviewed steganography and hybrid algorithms. From this study, we show that Advanced Encryption Standard is the most preferred standard for M-banking because there are no specific attacks against it so far. However, since technology is changing fast, Advanced Encryption Standard might not provide security in M-banking for long. Therefore, this study shows and recommends utilization of a combination of Advanced Encryption Standard algorithm and Least Significant Bit steganography to produce a robust hybrid algorithm that is tamperproof from flaws existing in current cryptosystems.

With the gradual maturity of the smart grid (SG), security challenges have become one of the important issues that needs to be addressed urgently. In SG, the identity authentication and key agreement protocol between a smart meter (SM) and an aggregator (AG) is a prerequisite for both parties to establish a secure communication. Some of the existing solutions require high communication cost, some have key escrow problems and security defects. Elliptic curve cryptosystem (ECC) holds the feature of low-key requirement and high security to make it more suitable for the security solutions to the communications in SG. In this paper, we propose a mutual anonymous authentication with an ECC-based key agreement scheme to secure the communications in SG. In addition, we compare our scheme with other existing schemes by the number of encryption operations, the computation delay, and the communication cost. The results indicate that our scheme is more efficient without the loss of safety properties.

The commercialization of 5G has greatly promoted the development of medical Internet of Things (IoT). More medical devices connected to the Internet may further increase the communication power consumption. Meanwhile, privacy protection technique in cloud computing cannot match the rapid development of medical applications. Therefore, exploring secure, balanced and energy-efficient data transmission between medical devices and cloud servers is extremely challenging. This paper focuses on the security and energy consumption of medical electronic health record (EHR) data transmission and storage between cloud server and IoT device users. We build a secure energy-saving communication and encrypted storage model by adding secure energy-saving communication scheme and encryption algorithm to the traditional medical cloud model. Specifically, we propose a communication authentication algorithm MedGreen based on elliptic curve and bilinear pair. In the algorithm, the two communication parties can complete the key establishment and identity authentication only after one communication, which effectively balances the resource overhead of the key center and the user, and resists the Man-in-the-middle attack. Aiming at the characteristics of large repetition and high sensitivity of medical data, we present a secure data storage algorithm MedSecrecy based on Huffman compression and RC4. The algorithm not only maintains the RC4 encryption efficiency, reduces the amount of cipher text data, but also improves confidentiality, randomness and security of the key stream. Comprehensive analysis and simulations show that our system is secure, energy-saving and highly efficient for EHR.
