摘要
The invention provides a system for encryptedly storing product data of a product having an attached tag centrally on a product data server, and reading out the centrally stored product data by production stations which are to process the product. The product data are encrypted with a document key which in turn is encrypted with a public key of the tag. The tag contains access information for the centrally stored product data. When a production station accesses product data on the product data server, the tag carries out a re-encryption of the document key from the key system of the tag to that of the accessing production station.
