The present invention discloses an IPv6 terminal identity
authentication method using 5GNR
physical layer information, which belongs to the field of
wireless communication security. First, a
mobile security communication
system model with eavesdroppers is constructed; then the two legal communication parties send detection signals to each other to estimate the
communication channel, and then decorrelate the channel
estimation matrix; the two legal communication parties respectively jointly quantize the phase and amplitude of the channel
estimation matrix after
decorrelation processing; the two legal communication parties generate consistent keys through a privacy coordination method based on BCH error
correction code; the two legal communication parties respectively perform hash
sequence transformation on the consistent keys obtained by each other to obtain the final key; the legal sender generates an identity
authentication tag through hash transformation based on the generated key and the source information to be transmitted, and sends it together with the source information; the legal
receiver generates an identity
authentication tag after hash transformation based on the received source information and the generated key, and compares it with the received identity authentication tag to complete the authentication process. The present invention effectively resists active attacks, does not have the problem of incompatibility with the underlying network, and solves the security leakage risk brought by
key distribution management, thereby enhancing the security of the
system.
