The U 盾 hardware encryption system by 达网 provides USB‑based secure login for websites, protecting against password leaks and attacks.
The U 盾 system uses a USB encryption dongle that stores unique user credentials. When the dongle is inserted, the website matches the stored data with its database, preventing unauthorized access and mitigating risks such as password leakage, SQL injection, and insider threats.
The solution supports all major browsers, allows IP‑range restrictions, multi‑factor verification, and can be configured for various scenarios including VIP member portals, corporate back‑office systems, OA platforms, and nationwide dealer networks. Hardware specifications such as interface type, algorithms, and environmental limits are detailed in the technical parameters section. This manual is written in Chinese.
