Communication Apparatus Protocol Compliance Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses face challenges in properly processing function execution requests from external information processing apparatuses that do not comply with communication protocols, leading to potential security issues and improper request handling.
Innovation Solution
A communication apparatus equipped with a communication unit, analysis unit, and execution unit that analyzes function execution requests and transmits responses according to the predetermined communication protocol, allowing for proper processing of requests that do not conform to protocol specifications, specifically executing specific functions when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication apparatus strictly follows communication protocol specifications when processing function execution requests, then security and protocol compliance are improved, but requests that do not comply with the protocol cannot be processed at all
Solution Approach 1:
The request processing is divided into two separate processing paths: one for requests that comply with the communication protocol specification and another for requests that do not comply. The analysis unit segments requests based on protocol compliance, allowing each path to be handled appropriately - compliant requests follow standard protocol processing while non-compliant requests can be evaluated for specific function execution without strict protocol adherence.
2Adaptability or versatility
If the communication apparatus processes all function execution requests regardless of protocol compliance, then request handling versatility is improved, but security risks increase due to improper processing of non-compliant requests
Solution Approach 1:
The analysis unit acts as an intermediary between the communication unit and the execution unit. It receives function execution requests, analyzes their protocol compliance, and determines whether to process them through the specific function execution path. This intermediary analysis step provides a security gate that evaluates non-compliant requests before allowing execution, preventing harmful requests from being processed while still permitting legitimate non-compliant requests.
3Reliability
If the communication apparatus treats all non-compliant requests as errors, then protocol strictness is maintained, but legitimate specific functions cannot be executed
Solution Approach 1:
The processing approach dynamically adapts based on the analysis of each request. For requests that comply with the protocol, standard protocol-based processing is applied. For requests that do not comply, the system dynamically evaluates whether they correspond to specific functions that should be executed. This dynamic processing strategy allows the system to maintain protocol enforcement for general cases while enabling productive execution of specific functions through alternative processing paths.

AI summary
A communication apparatus for communicating with an information processing apparatus includes a memory containing instructions and a processor to execute the instructions to function as a communication unit to perform communication between the communication apparatus and the information processing apparatus, an analysis unit to analyze an execution request of a function of the communication apparatus using a predetermined communication protocol that has been received from the information processing apparatus, and an execution unit to, when the execution request of the function is determined to not comply with a specification of the predetermined communication protocol because the execution request of the function does not include header information as a result of the analysis by the analysis unit, transmit a response using the predetermined communication protocol on condition that at least the execution request of the function is an execution request of a specific function, and execute the specific function.
