Solution Overview

Problem

The manual transcription of one-time passwords from hardware tokens to web pages is prone to errors, necessitating improved methods for interacting with memory devices in cryptographic operations.

Innovation Solution

A method and system that registers a cryptographic communication application with a web browser to handle messages encapsulated in specific protocols, enabling communication between a computing device and a memory device for cryptographic operations, thereby automating the process and reducing user involvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual transcription of one-time password from hardware token to web page is used, then user can authenticate to corporate network, but transcription errors occur and reliability deteriorates

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidmanual transcription operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

A web browser-based intermediary system is introduced between the hardware token and the authentication server. The browser receives the one-time password from the token, processes it through registered cryptographic applications, and automatically transmits it to the server, eliminating manual transcription while maintaining authentication reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical process of reading, memorizing, and transcribing the one-time password is replaced with an automated electronic system. The browser-based cryptographic application automatically captures and transmits the password digitally, substituting human manual operations with machine-to-machine communication

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If automated communication channel through web browser is established, then transcription accuracy improves, but device complexity increases

Engineering Contradiction:

Improvepassword transcription accuracyVSAvoidcommunication system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The web browser serves multiple functions: it acts as the communication interface, hosts cryptographic applications, manages protocol registration, and handles message encapsulation. This multi-functionality reduces the need for separate dedicated devices while maintaining high transcription accuracy through automated processes

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for interacting with a memory device is provided. In this method, a cryptographic communication application is registered to be associated with a protocol type in a web browser. A message encapsulated in the protocol type from the web browser is received and thereafter transmitted to the memory device. Here, the message is associated with a cryptographic operation.
