Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual password entry is used for decrypting encrypted broadcast audio, then security is maintained through user-controlled password input, but user experience deteriorates due to operation complexity and time consumption
Solution Approach 1:
The system enables automatic password acquisition where the listening device autonomously requests and receives the password from the broadcasting device through automated communication protocols, eliminating the need for manual user input while maintaining security through encrypted channels and authentication mechanisms
Solution Approach 2:
The patent introduces an automated password acquisition mechanism that acts as an intermediary between the user and the password entry process, where the system automatically handles password request, transmission, and decryption without requiring direct user interaction with the password field
2Ease of operation
If automated password acquisition is implemented using asymmetric encryption, then ease of operation is improved by eliminating manual entry, but device complexity increases due to encryption and check code verification mechanisms
Solution Approach 1:
The system performs preliminary key exchange and encryption setup before the actual password transmission, where asymmetric encryption keys are pre-established and check code verification mechanisms are pre-configured, allowing the password acquisition process to proceed automatically without complex real-time computations
Solution Approach 2:
The patent transforms the password transmission process by changing the cryptographic parameters used, employing asymmetric encryption algorithms and check code verification to securely transmit the password automatically, converting a simple manual entry task into a secure automated cryptographic process

AI summary
The present disclosure is related to a data processing method and apparatus, an electronic device, a storage medium and a computer program product. The method includes: in response to that a password acquisition request sent by a listening device is received, acquiring first key information and a random code from a broadcasting device based on a first communication connection with the broadcasting device; obtaining a second check code based on the first key information and the random code; checking a first check code acquired from the broadcasting device and the second check code to obtain a check result; in response to that the check result indicates that check is passed, acquiring password information from the broadcasting device; and sending the password information to the listening device, the password information being used for the listening device to decrypt broadcast audio received from the broadcasting device.
