A recently filed patent (Publication Number: US20240031408A1) outlines a method, device, and computer-readable medium for modifying data components of a message received from one device to align with the format of another device. The method involves selectively enabling access to library components specified in the modified data set, negotiating a cryptographic protocol based on the modifications, and adjusting ongoing communication accordingly. The modifications include establishing a fingerprint for the second device, encrypting communication based on library components, and replacing cipher suites during negotiation.

The device described in the patent includes processors and memories configured to carry out the data component modifications, library component access, cryptographic protocol negotiation, and ongoing communication adjustments. The processors are designed to establish a fingerprint for the second device, encrypt communication, and replace cipher suites as needed. Additionally, the patent covers a non-transitory computer-readable medium storing instructions for executing the same functions. This innovation aims to streamline communication between devices by ensuring data compatibility, secure encryption, and efficient negotiation of cryptographic protocols, ultimately enhancing the overall user experience and data security in device interactions.
