The disclosure provides an approach for layer 2 (L2) network security. Embodiments include determining that a new node has been added to an L2 network managed by a central control node. Embodiments include transmitting, to the new node, a certificate chain of the central control node, one or more supported encryption algorithms, and a shared key generation public key of the central control node. Embodiments include receiving, from the new node, a corresponding certificate chain of the new node, a selected encryption algorithm, and a corresponding shared key generation public key of the new node. Embodiments include generating a shared key based on the shared key generation public key of the central control node, and the corresponding shared key generation public key of the new node. Embodiments include establishing a secure communication session with the new node based on the selected encryption algorithm and the shared key.
