A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
OpenVPN has several ways to authenticate peers with each other. OpenVPN offers pre-shared keys, certificate-based, and username/password-based authentication.Preshared secret key is the easiest, and certificate-based is the most robust and feature-rich.
In computer networking, Secure Socket Tunneling Protocol (SSTP) is a form of virtual private network (VPN) tunnel that provides a mechanism to transport Point-to-Point Protocol (PPP) traffic through an SSL/TLS channel.
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
For example, the Computer Security Institute reported that in 2007, 71% of companies surveyed used encryption for some of their data in transit, and 53% used encryption for some of their data in storage. [20] Encryption can be used to protect data "at rest", such as information stored on computers and storage devices (e.g. USB flash drives). In ...
Data Protection Application Programming Interface (DPAPI) is a simple cryptographic application programming interface available as a built-in component in Windows 2000 and later versions of Microsoft Windows operating systems. In theory, the Data Protection API can enable symmetric encryption of any kind of data; in practice, its primary use in ...
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
The IPsec stack, in turn, intercepts the relevant IP packets if and where appropriate and performs encryption/decryption as required. Implementations vary on how the interception of the packets is done—for example, some use virtual devices, others take a slice out of the firewall, etc. IKEv1 consists of two phases: phase 1 and phase 2.
