Title: Innovations by Yongqiang Chen in Secure Authentication

Introduction

Yongqiang Chen is an accomplished inventor based in Gardenia, CA, known for his significant contributions to secure authentication technologies. With a total of two patents to his name, Chen has developed innovative methods that enhance the security of user credentials during online transactions.

Latest Patents

Chen's latest patents focus on methods and systems for secure authentication of users by host systems. One of his notable inventions involves a method for securely logging onto a banking system authentication server. This system ensures that a user's credential never appears in the clear during interactions with the system. The process involves DES encryption of the user's credential, with the DES key being PKI encrypted using the public key of an application server before transmission. The application server's hardware security module (HSM) then decrypts and re-encrypts the credential under a new DES key, ensuring secure verification by the authentication server.

Another patent by Chen also addresses secure authentication, detailing a process where an encryption applet and the public key of a banking application server are downloaded by a user's browser. This applet generates a DES key and performs both DES and PKI encryption. Similar to his first patent, the user's credential is DES encrypted, and the DES key is PKI encrypted before being sent to the application server, where it undergoes further secure processing.
