Access to the HS/FS via the Internet portal
Contents
The access process via the portal is described here in detail:

1.The user calls the HS/FS.

- The HS/FS checks the authorisation of the caller using the telephone number.
- If the caller is known, he receives a 5-digit random number as the PIN.
- PIN transfer is via language output.
- The PIN is only valid once for a time period that can be set.

2.After a valid call, the HS/FS connects to the Internet.

- Afterwards, it transfers the address in the Internet to the portal.
- The address transfer is encrypted with a password.
- This password is only known to the HS/FS and the portal operator.
- This password can be changed by the HS/FS owner at any time.

3.From his device, the user retrieves the portal page via the Internet.

- He enters the name of the HS/FS in the mask on the portal page.
- This name is only known to the user and can be changed at any time.
- The portal transfers the Internet address of the HS/FS.

4.The device of the user now automatically connects directly with the HS/FS.

- The portal is no longer involved in the further procedure.
- The HS/FS transfers a LOGIN mask to the user.
- The user must now enter the user name and the PIN received in 1).
- If authentication is positive, the HS/FS can now be operated.
- The transfer between HS/FS and user is encrypted.
Note
The portal takes on the function of a telephone directory service in order to search for the matching address (telephone number) using a known name.
The password which is known to the portal operator is only used for storing the HS/FS address.
The portal is no longer involved in the authentication of the user with the HS/FS.

This is emphasised again here because in the past there were often misunderstandings about this point.
The portal operation has no information which could enable access to the HS/FS.
All of the data required for authentication resides solely on the HS/FS,
and can only be changed locally using the start-up software.

A further important point is the use of a PIN for authentication that is only valid once.
This is especially relevant when accessing the HS/FS using devices that can be used by the public (e.g. Internet cafe, workstation, etc.).
This is because entries and passwords may be saved and recorded.
