Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple algorithms are included on a device as backup, then security coverage is improved, but the weak algorithm cannot be permanently disabled leading to security vulnerabilities
Solution Approach 1:
The patent implements dynamic algorithm management where the set of supported algorithms can be modified remotely over time. The network device can instruct the communication device to add, remove, or disable algorithms based on current security requirements, transforming the static algorithm set into a dynamic one that evolves with security threats.
Solution Approach 2:
The patent enables the extraction and removal of specific weak algorithms from the device's algorithm set while retaining stronger algorithms. This selective removal eliminates vulnerable algorithms that could be exploited in bidding down attacks, while preserving the functionality provided by secure algorithms.
2Duration of action of stationary object
If devices operate for long lifespans (20+ years), then device longevity is improved, but algorithms become vulnerable to brute force attacks over time
Solution Approach 1:
The patent implements preliminary security measures by establishing a mechanism before threats materialize. The network device proactively identifies and removes algorithms that may become vulnerable in the future, rather than waiting for actual attacks. This preventive approach ensures devices maintain security throughout their extended operational lifespan.
Solution Approach 2:
The patent establishes a feedback loop where the network device continuously monitors security conditions and algorithm strength requirements. Based on this feedback, the network device can instruct communication devices to update their algorithm sets, ensuring that security measures evolve in response to changing threat landscapes over time.
3Adaptability or versatility
If weak algorithms are used to ensure compatibility, then device interoperability is improved, but security is compromised through bidding down attacks
Solution Approach 1:
The patent creates a dynamic algorithm negotiation process where the set of supported algorithms is not fixed but can be updated remotely. This allows devices to maintain compatibility with stronger algorithms while the network can dynamically adjust which algorithms are permitted, preventing fallback to weak algorithms even if compatibility issues arise.

AI summary
An apparatus for enabling removal or disabling of weak algorithms may include a processor and memory storing executable computer program code that cause the apparatus to at least perform operations including receiving an indication of one or more algorithms utilized by a communication device. The computer program code may further cause the apparatus to determine whether one or more of the algorithms are identified as a weak algorithm. The computer program code may further cause the apparatus to enable provision of a message to the communication device instructing the communication device to remove, disable, or assign at least one condition to at least one detected weak algorithm among the algorithms. Corresponding methods and computer program products are also provided.
