Vulnerability Analysis of a Secure USB Memory: Based on a Commercial Product D

Secure USB products with security technology applied for safe data storage and storage of users have appeared. Secure USB products include user authentication technology, encryption/decryption technology, access control technology, and data deletion technology. Password authentication technology is widely used for user authentication. The objective of this study was to analyze vulnerabilities of password authentication technology based on the secure USB memory “product D” and identify possible vulnerabilities in advance based on analysis results. Results of the analysis revealed a vulnerability of the password authentication technology of “product D” and that user data could be stolen by bypassing the authentication.
