A Research on the Authentication Scheme For 5G Network Based on Double Ratchet Algorithm

Security threats faced in the 5G network communication is analyzed in this paper. For the 5G network provides high quality communication ability to every aspect of the society, the security situation becomes more challenging for each user in the 5G network. The authentication scheme is the first defending line for the 5G network system. The leakage of shared keys can cause serious security problem and an enhanced scheme for authentication based on double ratchet algorithm is proposed in this paper to ensure the end-to-end communication secrecy. Security analysis shows that the double ratchet algorithm can effectively enhance the communication security of the 5G network authentication method.
