Systems for Ensuring Secure Client/Server Transactions

Three basic ways to protect client / server transactions from security in the client / server transaction area. The first area is the firewall. The firewall monitors the basic idea of ​​traffic from a trusted network (the company's internal network) to an untrusted network (such as the Internet). There are two types of firewalls: "proxy" firewall and "packet filtering" firewall. Packet filtering determines whether or not to allow packets depending on the source and the contents of the packet.

Security: As many miners work in transactions, securing security is a bit complicated. Then, there is a multilayer security system in the block chain. Instant transactions can not be stopped if any layer is hacked. Therefore, testing one security layer does not affect the other. Data Transfer: Because data encryption and decryption is transferred from computer to computer, it is necessary to test whether the transfer process is functioning properly. Whether the transmitted data was received at the other end, or whether there was a loss between them. Therefore, you need to ensure that no data is lost.

Blockchain provides a fundamentally different way to ensure the information security of large systems beyond node servers, such as protecting user data and infrastructure. However, the block chain department faces a variety of challenges, including the development of network infrastructure, the peak of potential transactions, regulation of information storage, the ability to ensure data integrity, security, and reliability. Let's explain the main algorithms that improve the safety of the CREDITS platform over other block chain systems.

Assets that need to be protected to protect e-commerce in an e-commerce network include a client (shopper) computer or client, a transaction sent over the communication channel, a website on the server, and a server Includes merchant server including hardware. The server side communication channel is one of the main assets to be protected, but it is not the only concern for e - commerce security. The client security form is a user's point of view and is the primary security assurance; from the service provider's point of view, server side security is a big problem. For example, if the communication channel is secure, but there is no security measure on the client side or the server side, no secure transmission of information is done at all. According to Figure 3 above, an attacker or hacker can use several different security attack methods to attack the e - commerce network.
