Encrypted Authentication Data Management for Mobile Battery Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex manufacturing and supply chains for authentication devices are vulnerable to counterfeiting and data security concerns, as legitimate authentication devices can be siphoned off or stolen, and overproduced devices are difficult to track or detect, posing safety hazards and legal risks.
Innovation Solution
Storing authentication data in an encrypted format during the manufacturing process and transporting it on the authentication device itself, with decryption only accessible to trusted entities later in the process, ensures secure authentication and reduces counterfeiting motivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication data is stored in plaintext on authentication devices during manufacturing and transport, then decryption and authentication operations are fast and efficient, but the system becomes vulnerable to counterfeiting and data theft
Solution Approach 1:
The patent applies preliminary action by encrypting authentication data before it is stored on authentication devices during the manufacturing process. The data is encrypted using public-key cryptography, and the encrypted form is stored on the devices. This preliminary encryption action ensures that even if devices are stolen or data is intercepted during transport, the authentication data remains secure until it is decrypted at the point of use by authorized systems.
2Reliability
If authentication data is encrypted during manufacturing and transport, then security against counterfeiting is improved, but decryption operations add processing time and complexity
Solution Approach 1:
The patent replaces the mechanical approach of storing plaintext authentication data with a cryptographic system based on public-key infrastructure. Instead of relying on physical security measures alone, the system uses mathematical encryption methods that provide security without significantly impacting performance. The encryption and decryption operations are performed using standardized cryptographic algorithms that balance security strength with processing efficiency.
3Productivity
If authentication devices are manufactured and distributed before final assembly, then manufacturing efficiency and productivity are improved, but the risk of device siphoning and overproduction increases
Solution Approach 1:
The patent applies preliminary anti-action by implementing encryption as a preventive measure against future security threats. By encrypting authentication data before devices are fully assembled or distributed, the system proactively neutralizes the risk of counterfeiting and data theft. This preliminary protective action ensures that even if devices are stolen or diverted during the manufacturing process, the authentication data cannot be misused, thereby preventing potential harm before it can occur.

AI summary
Methods, systems, and computer programs for managing authentication data for an authentication device are disclosed. An authentication device may be included, for example, in a mobile device battery so that the battery can be authenticated by a mobile device. In some implementations, encrypted certificate data are stored on an authentication device. The encrypted certificate data are accessed, and unencrypted certificate data are generated by decrypting the encrypted certificate data. The unencrypted certificate data are stored on the authentication device. The unencrypted certificate data enable the authentication device to provide a valid reply message, for example, in response to receiving an interrogation message from an interrogation device. In some implementations, the reply message includes the unencrypted certificate data and a response value generated by the authentication device based on a secret value.
