Remote Decryption Service for Encrypted Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without local decryption capabilities, such as those in restrictive business environments or using public terminals, face difficulties in accessing encrypted email messages due to the requirement of installing decryption software.
Innovation Solution
Implementing a remote decryption service that allows users to upload encrypted content for decryption, using a URL embedded in the message to direct the user to a web page where they can authenticate and upload the encrypted content, which is then decrypted by the service and made accessible over the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decryption software is installed locally on user devices, then decryption capability is improved, but device complexity and installation requirements increase
Solution Approach 1:
The patent introduces a remote decryption service as an intermediary between the encrypted message and the user. Instead of requiring decryption software on the user's device, the system uses a web-based decryption service that users can access through a standard web browser. The service receives encrypted messages, performs decryption remotely, and delivers decrypted content back to the user, eliminating the need for local decryption software installation.
2Speed
If decryption software is installed locally, then decryption speed is improved, but ease of operation deteriorates due to installation restrictions
Solution Approach 1:
The remote decryption service enables users to decrypt messages using only a web browser, which is already installed on most devices. The service handles all decryption operations self-service style through web interfaces, allowing users to access encrypted messages without needing to install additional software or configure complex local decryption environments.
3Ease of operation
If remote decryption service is used, then ease of operation is improved, but loss of time increases due to upload and download processes
Solution Approach 1:
The system performs preliminary actions by pre-configuring web-based decryption interfaces and establishing ready-to-use decryption services before users need them. When users receive encrypted messages, the decryption infrastructure is already in place and can immediately process requests without requiring any setup time or software installation delays.

AI summary
Systems and methods for secure messaging are provided. A sender may encrypt content and send the encrypted content to a recipient over a communications network. The encrypted content may be decrypted for the recipient using a remote decryption service. Encrypted message content may be placed into a markup language form. Encrypted content may be incorporated into the form as a hidden form element. Form elements for collecting recipient credential information such as username and password information may also be incorporated into the form. At the recipient, the recipient may use the form to provide recipient credential information to the remote decryption service. The recipient may also use the form to upload the encrypted content from the form to the decryption service. The decryption service may provide the recipient with access to a decrypted version of the uploaded content over the communications network.
