Information Apparatus Remote Access Security Speed Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote access technologies face challenges in providing a suitable environment for secure and efficient remote operation of information apparatuses, particularly in balancing communication speed and security based on the access location, with existing solutions struggling to adapt to different use scenarios effectively.
Innovation Solution
The information apparatus includes circuitry that processes both plaintext and ciphertext communication requests by decrypting ciphertext requests and transferring them for processing, allowing for secure and efficient remote operation by switching ports and using encryption/decryption units, enabling secure communication protocols like HTTPS and HTTP based on the access method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ciphertext communication requests are used for remote access, then security is improved, but communication speed and processing efficiency deteriorate due to decryption overhead
Solution Approach 1:
The patent applies different communication protocols (plaintext vs ciphertext) to different access scenarios. External access uses ciphertext (HTTPS) for security, while internal network access uses plaintext (HTTP) for speed. This local differentiation resolves the contradiction by matching security measures to actual security needs in each context.
Solution Approach 2:
The system dynamically selects between plaintext and ciphertext communication modes based on the access source. The communication protocol is not fixed but adapts according to whether the request comes from inside or outside the company network, optimizing both security and efficiency in real-time.
2Adaptability or versatility
If a single communication protocol is used for all access scenarios, then device complexity is reduced, but adaptability to different security requirements deteriorates
Solution Approach 1:
The patent segments the communication processing into two distinct paths: one for plaintext requests and one for ciphertext requests. Each path has its own processing logic, allowing the system to handle different security requirements independently without complicating the overall architecture.
Solution Approach 2:
The communication processing unit is designed to handle both plaintext and ciphertext protocols universally. A single unit performs both decryption (for ciphertext) and direct processing (for plaintext), eliminating the need for separate processing systems while maintaining adaptability to different access scenarios.
Data Source
AI summary
An information apparatus includes circuitry to receive a communication request transmitted from a request source device. The communication request is one of a plaintext communication request and a ciphertext communication request. In response to receiving the plaintext communication request, the circuitry transfers the plaintext communication request for processing. In response to receiving the ciphertext communication request, the circuitry decrypts the ciphertext communication request to obtain another communication request and transfers the another communication request for processing.
