Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in reducing latency during secure data transmission and decryption, particularly in low-latency environments like the Internet of Vehicles, where timely reception of emergency information is critical.
Innovation Solution
A transmission data protection mechanism using a bloom filter and multiple randomization arrays to securely process data in two stages, allowing for rapid secure processing and recovery, thereby minimizing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encryption algorithms (DES or AES) are used to secure data before transmission, then data security is improved, but transmission latency increases and real-time information cannot be obtained timely
Solution Approach 1:
The patent changes the fundamental parameters of the encryption approach by replacing traditional DES/AES algorithms with a bloom filter-based randomized encoding scheme. This alternative parameter set (hash functions, bit array operations) inherently reduces computational complexity and processing time while maintaining security through randomness and one-way functions, directly resolving the latency-security contradiction
Solution Approach 2:
The patent extracts the essential security function from traditional encryption by using only the one-way hashing and randomization capabilities, eliminating the computationally intensive symmetric key operations of DES/AES. The bloom filter structure extracts only the necessary components (hash functions and bit arrays) to achieve both security and speed, discarding the heavy cryptographic machinery that caused latency
2Loss of time
If rapid decryption is performed to reduce latency, then real-time information reception is improved, but data security is compromised
Solution Approach 1:
The patent inverts the traditional encryption-decryption paradigm by using one-way hash functions that naturally resist reversal. Instead of attempting to decrypt encrypted data, the system generates fresh random data through the bloom filter that inherently cannot be reversed to obtain original input, providing security without requiring decryption operations, thus eliminating the time-security tradeoff
Solution Approach 2:
The randomized data generated by the bloom filter is self-sufficient for security purposes. The randomization arrays and hash functions create data that is inherently secure and does not require additional decryption steps or key management, making the security mechanism self-contained and eliminating latency associated with traditional decryption processes
Data Source
AI summary
A transmission apparatus and a transmission data protection method thereof are provided. The transmission apparatus stores a data table, a bloom filter, a first randomization array, a plurality of second randomization arrays and an identifier of each of the second randomization arrays. The bloom filter has a plurality of independent hash functions. The transmission apparatus generates a current original datum according to the data table; inputs the current original datum to the bloom filter as a current input datum of the bloom filter to output a current bloom datum; randomizes the current bloom datum according to the first randomization array to generate a current first randomized datum; randomizes the current first randomized datum according to one of the second randomization arrays to generate a current second randomized datum; and transmits a data signal carrying the current second randomized datum and an identification datum to another transmission apparatus.
