Design and Development of Smart Security Key for Knowledge based Authentication

Ensuring the safety of passwords has always been a paramount concern for online users, however, numerous individuals still become a victim of identity theft due to the presence of multiple attack types such as brute-force, phishing, and dictionary attacks. These attacks can compromise the users' accounts, and dictionary attacks seem to be the most prevalent. To improve security and safeguard the privacy of users, a new methodology is proposed that involves a sophisticated digital key incorporating cutting-edge biometric and fingerprint sensor technologies along with embedded cryptography. This key generates passwords that are distinct and sturdy, which are impervious to cracking, and utilizes the Advanced Encryption Standard (AES) algorithm to encrypt and decrypt them. This mechanism offers a new means of securely managing passwords with less user intervention and a heightened level of security compared to traditional authentication techniques.
