Access Token Usage Attributes Mitigate 5G Token Misuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G telecommunications networks, access tokens can be stolen and reused for unauthorized access or denial-of-service attacks due to their reusability, as existing security procedures like OAuth 2.0 do not effectively mitigate misuse, especially since tokens can be used multiple times before expiration.
Innovation Solution
Implementing access tokens with usage attributes such as message rate limits and message count limits, which are tracked and enforced by network functions to reject service requests if these limits are exceeded, thereby preventing misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If access tokens are made reusable for multiple service requests, then ease of operation is improved, but security deteriorates due to potential token theft and misuse
Solution Approach 1:
The patent applies preliminary action by embedding usage attributes (message rate limit, message count limit) into the access token before it is used. This pre-configured usage information enables the token to self-regulate its own usage without requiring real-time verification with the NRF, thus maintaining ease of operation while preventing security issues through pre-established constraints.
Solution Approach 2:
The patent changes the parameters of the access token by adding usage attributes (message rate limit, message count limit) to the traditional token structure. These additional parameters enable the token to carry usage control information, transforming it from a simple authentication credential into a self-regulating authorization token that can prevent misuse while maintaining reusability.
2Productivity
If access tokens have long expiration times, then productivity is improved by reducing re-authentication frequency, but security deteriorates as stolen tokens remain valid longer
Solution Approach 1:
The patent applies preliminary action by embedding usage attributes (message rate limit, message count limit) into the access token before it is used. This pre-configured usage information enables the token to self-regulate its own usage without requiring real-time verification with the NRF, thus maintaining ease of operation while preventing security issues through pre-established constraints.

3Reliability
If usage tracking and enforcement mechanisms are implemented, then security is improved by preventing token misuse, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the access token to self-regulate its own usage through embedded usage attributes. The token itself contains the message rate limit and message count limit information, allowing it to autonomously determine whether a service request should be permitted without requiring external verification. This eliminates the need for complex tracking systems at the NRF or producer NF, as the token performs the usage control function independently.

AI summary
Methods, systems, and computer readable media for mitigating effects of access token misuse are disclosed. One example method for mitigating effects of access token misuse comprises: at a network function (NF) comprising at least one processor: receiving, from a sender, a service request comprising an access token, wherein the access token includes an access token identifier and usage attributes indicating a message rate limit and/or a message count limit; determining, using the usage attributes associated with the access token, that the service request should be rejected; and rejecting the service request.
