Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in ensuring secure and reliable configuration sharing over reference signals, especially in the presence of malicious entities that can intercept and manipulate authentication credentials.
Innovation Solution
The implementation of a mutual authentication process using multiple-input and multiple-output (MIMO) signals, where network nodes exchange authentication requests and responses through multiple MIMO paths, ensuring that both nodes are authenticated before sharing configuration information.

Engineering Contradiction Analysis
1Productivity
If configuration sharing is performed over reference signals in wireless communication systems, then communication efficiency is improved, but security against eavesdropping and manipulation by malicious entities deteriorates
Solution Approach 1:
The patent applies preliminary action by performing mutual authentication between transmitter and receiver before configuration sharing. The authentication process using MIMO paths and authentication proofs is executed in advance to establish security credentials, ensuring that only authenticated nodes can participate in configuration sharing. This preliminary security setup prevents eavesdropping and manipulation during the actual configuration transmission.
Solution Approach 2:
The patent uses MIMO paths as an intermediary mechanism for secure configuration sharing. Multiple MIMO paths provide diverse transmission routes that are harder to intercept or manipulate. The authentication proof acts as an intermediary credential that mediates the trust relationship between nodes, allowing secure configuration exchange without exposing the actual configuration data to potential eavesdroppers.
2Reliability
If authentication credentials are exchanged during configuration sharing, then security is improved, but vulnerability to credential interception and manipulation by malicious entities worsens
Solution Approach 1:
The patent segments the authentication process into multiple independent phases: authentication request transmission, authentication proof exchange, and configuration sharing. Each phase uses separate MIMO paths and credentials. This segmentation ensures that even if one authentication credential is intercepted, the overall security is not compromised because other segments remain secure. The configuration sharing is separated from authentication credential exchange, so credentials are not exposed during configuration transmission.
Solution Approach 2:
The patent adds spatial dimensionality to authentication by using multiple MIMO paths for different authentication phases. Instead of exchanging all authentication credentials through a single channel, the system uses diverse spatial paths (different antenna combinations and signal routes) for authentication requests, proofs, and configuration sharing. This dimensional diversification makes interception and manipulation significantly more difficult for malicious entities.
3Reliability
If multiple MIMO paths are used for authentication exchange, then security against eavesdropping is improved, but system complexity worsens
Solution Approach 1:
The patent applies universality by using MIMO paths for multiple functions: authentication request transmission, authentication proof exchange, and configuration sharing. The same MIMO infrastructure serves all these security-critical functions, reducing the need for separate dedicated channels for each operation. This multi-functionality approach maintains security through path diversity while avoiding the complexity of managing entirely separate communication infrastructures for each authentication phase.

AI summary
Systems and techniques are described herein for mutual authentication in wireless communication. For example, a process may include: transmitting separate authentication requests using separate MIMO channels between network nodes; transmitting an authentication proof from one network node to another; receiving configuration requests based on successful authentication of one network node by the other over the respective MIMO paths; authenticating the configuration requests; and transmitting separate configuration responses via the separate MIMO paths based on the authentication.
