Latest Patents

Takeshi Hosoi's latest patents include:

1. **Method for synchronization in encrypted communications using shared key**

This patent discloses a method for achieving synchronization of a running key generated from a shared key, which is essential for encryption and decryption in communications. The method employs a multi-valued signal where the transmitting node sends a signal with a fixed pattern before data transmission. The receiving node adjusts its bit discrimination threshold signal phase to match the fixed pattern signal, enabling successful synchronization of the running key between both nodes.

2. **Method and system for encrypted communications using multi-valued modulation**

In this invention, the transmitting node inserts synchronization data into plain text, which is then encrypted into multi-valued data for transmission. The synchronization data indicates the position of the running key used during encryption. The receiving node is tasked with decrypting the signal, confirming synchronization, and communicating back to the transmitting node. If synchronization confirmation is not received, the transmitting node initiates re-synchronization, ensuring a seamless communication process.
