Avatar Object Encryption with Attestation in Wireless Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In avatar communication scenarios, unauthorized users can potentially misuse avatar objects, posing a security threat by impersonating the actual owner, necessitating secure transmission methods.
Innovation Solution
A method and apparatus for secure transmission of avatar objects in wireless communication systems, involving a transmitting UE and network entity that establish a channel, exchange attestation information, and encrypt the avatar object based on verification, ensuring only authorized users can access and render the avatar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If avatar objects are transmitted without encryption in wireless communication systems, then transmission efficiency and ease of operation are improved, but security and reliability deteriorate as unauthorized users can misuse avatar objects and impersonate actual owners
Solution Approach 1:
The system performs attestation information verification and encryption operations in advance before avatar object transmission. The transmitting UE generates attestation information proving ownership, and the network entity verifies this information and establishes encryption keys beforehand, ensuring secure transmission without compromising operational efficiency
Solution Approach 2:
The network entity acts as an intermediary that mediates between the transmitting UE and the rendering entity. It verifies attestation information, manages encryption keys, and controls the distribution of encrypted avatar objects, thereby centralizing security management and reducing complexity at the device level
2Reliability
If attestation information verification and encryption are implemented for avatar object transmission, then security and authorization control are improved, but transmission time and processing duration increase
Solution Approach 1:
The system establishes encryption keys and verifies attestation information in advance during the initial connection phase. Once verified, the encrypted avatar objects can be transmitted efficiently without repeated verification overhead, reducing time loss during actual transmission
Solution Approach 2:
The encryption and verification processes are integrated into the continuous communication flow rather than being separate batch operations. The network entity maintains active verification states and encryption contexts throughout the communication session, eliminating redundant processing and minimizing time loss

AI summary
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a transmitting UE for providing an avatar service through avatar communication includes establishing a channel for the avatar communication with a network entity and a UE receiving the avatar service, transmitting, to the network entity, attestation information including identification information of an avatar object to be used for the avatar communication by the transmitting UE, and an encryption information of a rendering entity generated by the rendering entity, and acquiring data required for rendering corresponding to the encrypted avatar object based on the encryption information of the rendering entity. The encrypted avatar object is encrypted based on verification of the attestation information and the identification information. The encrypted avatar object is provided to the rendering entity.
