Host Identity Protocol version 2 (HIPv2), also known as HIP version 2, is an update to the protocol that enhances security and support for mobile environments. HIP continues to separate the roles of identification and location in IP addressing by implementing a host identity namespace based on cryptography.

Host Identity Payload (HIP): provides a mechanism by which the identity of the equipment or its user is carried securely in every packet. Public Key Infrastructure (PKI): provides cryptographic identities for the HIP protocol. Secure Directory: retains information about the user, the owner, the machine, and other policy relevant information.
The task of the authentication protocol is to specify the exact series of steps needed for execution of the authentication. It has to comply with the main protocol principles: A Protocol has to involve two or more parties and everyone involved in the protocol must know the protocol in advance. All the included parties have to follow the protocol.
Structure. A pluggable authentication module (PAM) is a mechanism to integrate multiple low-level authentication schemes into a high-level application programming interface (API).
The tickets have a time availability period, and if the host clock is not synchronized with the Kerberos server clock, the authentication will fail. The default configuration per MIT requires that clock times be no more than five minutes apart. In practice, Network Time Protocol daemons are usually used to keep the host clocks synchronized ...
TACACS Plus (TACACS+) is a protocol developed by Cisco and released as an open standard beginning in 1993. Although derived from TACACS, TACACS+ is a separate protocol that handles authentication, authorization, and accounting (AAA) services. TACACS+ has largely replaced its predecessors.
RADIUS is an AAA (authentication, authorization, and accounting) protocol that manages network access. RADIUS uses two types of packets to manage the full AAA process: Access-Request, which manages authentication and authorization; and Accounting-Request, which manages accounting.
