Medical Device Secure Data Transmission via Independent Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for secure data transmission between medical devices and other devices, such as computers, lack effective security measures to ensure the confidentiality and integrity of sensitive electronic data, particularly in medical contexts.
Innovation Solution
A method involving the use of independent transmission channels, where a password is provided and used to encrypt channel identification, allowing for secure selection and use of a transmission channel, and generation of session keys for encryption and decryption of data, enhancing security through cryptographic processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic methods are used to encrypt electronic data during transmission, then data security is improved, but the complexity of key management and channel selection increases
Solution Approach 1:
The patent segments the key management process into distinct components: password for channel identification encryption, and session key for data encryption. This segmentation allows each key to have a specific purpose, simplifying overall key management while maintaining high security standards for data transmission.
Solution Approach 2:
The patent implements preliminary action by establishing the password and selecting the transmission channel before actual data transmission begins. The channel identification is encrypted using the password in advance, and the session key is generated and distributed before data exchange, ensuring security measures are in place prior to sensitive operations.
2Reliability
If a password is transmitted separately from the data communication link, then security against eavesdropping is improved, but the transmission time and process complexity increase
Solution Approach 1:
The patent uses an intermediary approach by transmitting the password through a separate communication link that is independent of the main data transmission channel. This intermediary channel is used solely for establishing security credentials, preventing eavesdroppers on the main channel from obtaining the password, while the separate transmission minimizes time loss by using dedicated efficient channels.

AI summary
Secure transmission of electronic data via a data communication link is provided between a device and an additional device with independent transmission channels, wherein at least one of the devices is a medical device. Secure transmission comprises the following steps or means: providing a password in the device, receiving the password in the a additional device separate from the data communication link, selecting one of the independent transmission channels, encrypting the channel identification of the selected independent transmission channel using the received password in the additional device, transmitting the encrypted channel identification from the additional device to the device via the data communication link and decrypting the encrypted channel identification in the device, providing a session key in the device and the additional device and transmitting encrypted electronic data between the device and the additional device via the independent transmission channel.
