Block-hash of blockchain framework against man-in-the-middle attacks

Abstract

Payload authentication is vulnerable to Man-in-the-middle (MITM) attack. Blockchain technology offers methods such as peer to peer, block hash, and proof-of-work to secure the payload of authentication process. The implementation uses block hash and proof-of-work methods on blockchain technology and testing is using White-box-testing and security tests distributed to system security practitioners who are competent in MITM attacks. The analyisis results before implementing Blockchain technology show that the authentication payload is still in plain text, so the data confidentiality has not minimize passive voice. After implementing Blockchain technology to the system, white-box testing using the Wireshark gives the result that the authentication payload sent has been well encrypted and safe enough. The percentage of security test results gets 95% which shows that securing the system from MITM attacks is relatively high. Although it has succeeded in securing the system from MITM attacks, it still has a vulnerability from other cyber attacks, so implementation of the Blockchain needs security improvisation.

TAARA Method for Processing on the Network Forensics in the Event of an ARP Spoofing Attack

“…Other studies use the forensic process model when performing network forensics on MITM attacks, which are part of advanced network attacks [14]. MITM attacks are frequently linked to credential theft, which is considered a cybercrime, and a method for sniffing the victim's network traffic communications against the gateway that are exchanged between users in some systems covertly [15], [16] . Among the cybercrime attacks mentioned, the effect of the ARP spoofing attack initiator is one example [17][18][19].…”
