In the current scenario, various forms of information are spread everywhere, especially through the Internet. A lot of valuable information is contained in the dissemination, so security issues have always attracted attention. With the emergence of cryptographic algorithms, information security has been further improved. Generally, cryptography encryption is divided into symmetric encryption and asymmetric encryption. Although symmetric encryption has a very fast computation speed and is beneficial to encrypt a large amount of data, the security is not as high as asymmetric encryption. The same pair of keys used in symmetric algorithms leads to security threats. Thus, if the key can be protected, the security could be improved. Using an asymmetric algorithm to protect the key and encrypting the message with a symmetric algorithm would be a good choice. This paper will review security issues in the information transmission and the method of hybrid encryption algorithms that will be widely used in the future. Also, the various characteristics of algorithms in different systems and some typical cases of hybrid encryption will be reviewed and analyzed to showcase the reinforcement by combining algorithms. Hybrid encryption algorithms will improve the security of the transmission without causing more other problems. Additionally, the way how the encryption algorithms combine to strength the security will be discussed with the aid of an example.

An Overview and Analysis of Hybrid Encryption: The Combination of Symmetric Encryption and Asymmetric Encryption

Modern technology is turning into an essential element in the financial trade. We focus the emphasis of this review on the research on the E-wallet and online payment, which is an element of an electric payment system, to get the pattern of using this service. This research presents a review of 131 research articles published on electronic payment between 2010 and 2020 that uses a qualitative method of answering the research questions (RQ): RQ1: “What are the major security issues regarding using electronic payments”? and RQ2: “What security properties need to comply for secure electronic payments?” With the systematic literature review approach, the results show that interest in E-wallet and online payment has grown significantly during this period, and it was found that for the increasing uses of electronic payments, researchers are more focused on security issues. The results show that, to conquer the key gaps, electronic payment must have some protection properties, namely, availability, authorization, integrity, non-repudiation, authentication, and confidentiality. Nowadays, security problems in electronic payment are usually more demanding than the present security problems on the web. These findings can enable electric transaction providers to strengthen their security methods by boosting their security gaps, as required for relevant services.

A Review on Electronic Payments Security

The Covid-19 pandemic struck Indonesia and also the rest of the world, which has a huge impact in the Micro, Small and Medium Enterprises (MSMEs). It is necessary to have a big movement to revive the economic passion in Indonesia, especially MSMEs, one of which is by utilizing e-commerce. This paper presents a conceptual framework for adopting e-commerce. Based on the results of a review of several articles, it was concluded that three factors could be used to adopt e-commerce, including, organizational characteristics, environmental characteristics, and leadership characteristics. To test the benefits and ease of using e-commerce, it can use the Technology Acceptance Model (TAM) theory.

With the explosion of connected devices linked to one another, the amount of transmitted data grows day by day, posing new problems in terms of information security, such as unauthorized access to users’ credentials and sensitive information. Therefore, this study employed RSA and ElGamal cryptographic algorithms with the application of SHA-256 for digital signature formulation to enhance security and validate the sharing of sensitive information. Security is increasingly becoming a complex task to achieve. The goal of this study is to be able to authenticate shared data with the application of the SHA-256 function to the cryptographic algorithms. The methodology employed involved the use of C# programming language for the implementation of the RSA and ElGamal cryptographic algorithms using the SHA-256 hash function for digital signature. The experimental result shows that the RSA algorithm performs better than the ElGamal during the encryption and signature verification processes, while ElGamal performs better than RSA during the decryption and signature generation process.

Enhancement of e-commerce security through asymmetric key algorithm

Electronic commerce, or E-commerce, is conducting business over the Internet. Usually it refers to buying and selling goods and services, and transferring funds digitally. There are many benefits to Electronic commerce business, not the least of which is reduced transaction costs. When offline stores calculate transaction costs, they have to factor in countless business expenditures along with the actual number of transactions. When there are fewer transactions, the cost of per transaction is higher. On the other hand, transactions arriving in high quantity can overwhelm your personnel and distributors.
