Embodiment Construction
[0034] The present invention will be further clarified below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.
[0035] Several entities involved in the temporary identification management mechanism involved in the present invention.
[0036] The present invention involves two entities: the mobile user and the home network. The home network will randomly group with mobile users. And generate a random group identity pool, and generate a random identity pool for each user, use a bloom filter to map the group identity pool. After the user submits the authentication information, the home network verifies his identity, confirms the group to which the user belongs, verifies the user identity, and finally accesses the network.
[0037] The present invention includes two major parts: a temporary ide...

The invention discloses a reliable and efficient 5G anonymous authentication method, including a possible temporary identification management mechanism based on Bloom filter, hash chain and identification pool, and a corresponding anonymous authentication mechanism. The temporary ID management mechanism includes the following steps: grouping users; generating a random group ID pool; generating a user random ID pool; mapping the group ID pool using a Bloom filter; and using a Bloom filter to map the user ID pool. The anonymous authentication mechanism includes the following steps: user submits authentication information; home network verifies user identity; access authentication protocol design. The present invention fulfills the need for privacy protection of mobile users in 5G access authentication, well solves the problem of lost identification synchronization relationship in the existing 5G access authentication technology, and greatly improves authentication performance.
Description
technical field [0001] The invention belongs to the technical field of privacy security, and in particular relates to a reliable and efficient 5G anonymous authentication method. Background technique [0002] As mankind enters the 5G era, the new technology of 5G network brings new security risks and challenges. Compared with traditional 3G / 4G networks, the 5G core network is based on new technologies such as network function virtualization, providing more ubiquitous access support, more flexible control and forwarding mechanisms, and a more friendly capability opening method in terms of architecture and functions. . 5G network new technologies and new services bring convenience, but also security risks and challenges. Faced with these risks and challenges, it is necessary to conduct research on user anonymity. [0003] In 5G, when mobile users access the network, they will send their own hidden identity SUCI or temporary identity GUTI in plain text for authentication. T...
