Multi-Level Tagged Encrypted Cookie Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current encryption techniques for HTTP cookies provide minimal security and are inefficient, as they lack fine-grained control and often apply the same encryption methods to all cookies, leading to security risks and inefficiencies.
Innovation Solution
Implementing multi-level tagging of encrypted items, allowing for per-profile encryption options, using a common key for cookies and storing session cookies separately to enhance security and efficiency, with customizable flags and internal checks to manage encryption and decryption processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same encryption techniques are applied to all cookies, then security coverage is improved, but system efficiency deteriorates due to unnecessary encryption of all cookies
Solution Approach 1:
The patent segments cookies into different categories (session cookies, persistent cookies, secure cookies, non-secure cookies) and applies encryption selectively based on cookie attributes and security requirements. This allows the system to encrypt only necessary cookies rather than all cookies, resolving the contradiction between comprehensive security coverage and system efficiency.
Solution Approach 2:
The patent implements differential encryption policies where different encryption techniques and strength are applied to different cookies based on their specific characteristics and security needs. Session cookies receive different treatment than persistent cookies, and secure cookies receive enhanced encryption compared to non-secure cookies, optimizing both security and performance.
2Reliability
If encryption is applied to all cookies, then security is improved, but device complexity increases due to managing encryption for every cookie type
Solution Approach 1:
The patent creates a universal encryption management system that handles multiple cookie types (session, persistent, secure, non-secure) through a unified framework. The system automatically determines which cookies require encryption based on predefined criteria and applies appropriate encryption methods, reducing the complexity of managing encryption across diverse cookie types while maintaining comprehensive security.
3Measurement precision
If all cookie values are decrypted to determine encryption status, then accuracy is improved, but processing time increases significantly
Solution Approach 1:
The patent implements preliminary tagging of cookies with encryption status indicators before they are transmitted. The device adds metadata tags to cookies indicating their encryption status, allowing the receiving device to determine encryption status instantly without decrypting the cookie values. This preliminary action resolves the contradiction between accurate encryption status determination and processing time efficiency.
4Adaptability or versatility
If per-profile encryption options are implemented, then adaptability is improved, but device complexity increases due to multiple encryption configurations
Solution Approach 1:
The patent implements dynamic encryption configuration where encryption policies can be adjusted per profile (e.g., development, testing, production environments). The system automatically selects appropriate encryption settings based on the active profile, providing adaptability across different use cases while simplifying configuration management through automated profile-based policy selection rather than manual configuration of each setting.

AI summary
The present disclosure is directed towards systems and methods for performing multi¬ level tagging of encrypted items for additional security and efficient encrypted item determination. A device intercepts a message from a server to a client, parses the message and identifies a cookie. The device processes and encrypts the cookie. The device adds a flag to the cookie indicating the device encrypted the cookie. The device re-inserts the modified cookie into the message and transmits the message. The device intercepts a message from a client and determines whether the cookie in the message was encrypted by the device. If the message was not encrypted by the device, the device transmits the message to its destination. If the message was encrypted by the device, the device removes the flag, decrypts the cookie, removes the tag from the cookie, re-inserts the cookie into the message and transmits the message to its final destination.
