Installation of a terminal in a secure system
First Claim
1. A system comprising a terminal and a server, wherein the terminal is installed in the system by the server being configured to:
- identify the terminal;
generate key generation data, comprising at least one data seed;
distribute the at least one data seed to the terminal;
generate key data, to be used for generating a symmetric encryption key, and meta data, to be used for generating an authentication token, based on said at least one data seed and a function for generating numbers;
store an identifier for the terminal along with the key data and the meta data for the terminalgenerate a random encryption key;
distribute the random encryption key to the terminal; and
encrypt the at least one data seed with the random encryption key, wherein the terminal is arranged to;
receive the at least one data seed from the server;
generate key data and meta data based on said at least one data seed and the same function for generating numbers;
store the key data and the meta data, wherein the key data and the meta data stored in the terminal are the same as the key data and the meta data stored in the server;
receive the random encryption key;
receive the encrypted at least one data seed from the server; and
decrypt the at least one data seed with the random encryption key.

Abstract
A system comprising a terminal and a server, wherein the terminal is installed in the system by the server being configured to: identify the terminal; generate key generation data, comprising at least one data seed; distribute the at least one seed to the terminal; generate key data and meta data based on said at least one seed and a function; store an identifier for the terminal along with the key data and the meta data for the terminal, wherein the terminal is arranged to receive the at least one seed from the server; generate key data and meta data based on said at least one seed and the same function; store the key data and the meta data, wherein the key data and the meta data stored in the terminal are the same as the key data and the meta data stored in the server.

7. A method for use in a system comprising a terminal and a server, said method being for installing the terminal in the system, the method comprising:
-
the server identifying the terminal; the server generating key generation data, comprising at least one data seed; the server distributing the at least one data seed to the terminal; the server generating key data, to be used for generating a symmetric encryption key, and meta data, to be used for generating an authentication token, based on said at least one data seed and a function for generating numbers; the server storing an identifier for the terminal along with the key data and the meta data for the terminal; the server generating a random encryption key; the server distributing the random encryption key to the terminal; the server encrypting the at least one data seed with the random encryption key; the terminal receiving the at least one data seed from the server; the terminal generating key data and meta data based on said at least one data seed and the same function for generating numbers; the terminal storing the key data and the meta data, wherein the key data and the meta data stored in the terminal are the same as the key data and the meta data stored in the server; the terminal receiving the random encryption key; the terminal receiving the encrypted at least one data seed from the server; and the terminal decrypting the at least one data seed with the random encryption key. - View Dependent Claims (8, 9, 10, 11, 12)
