METHOD FOR AUTHENTICATING A COMPUTER SYSTEM

The invention relates to a method for authenticating a first computer system (100) to a second computer system (200). A third computer system (300) provides an authentication file containing authentication data for authenticating the first computer system (100). A certificate (112) issued for the first computer system (100) comprises a reference (128) for identifying the authentication data. The third computer system (300) receives a read request from the second computer system (200) for reading the authentication data, wherein the read request identifies the authentication data by using the reference (128). In response to reception of the read request, the third computer system (300) transmits the requested authentication data to the second computer system (200).
