Title: Peter Oberparleiter and Secure Initial Program Load Code Loading

Introduction

Peter Oberparleiter is an inventor associated with Dettenhausen, Germany, and International Business Machines Corporation. His patent work addresses secure software loading during the Initial Program Load (IPL) process, helping protect systems from malicious code injection.

Latest Patents

Oberparleiter is associated with 1 patent: “Secure Initial Program Load (IPL) Code Loading Attributes Facility.” The invention describes appending a secure code loading attributes block (SCLAB) to a variable-sized, signed binary code component to create a combined component, which is then digitally signed. The SCLAB contains a length field, an identifier, flag fields, a load program status word, and a load address. During IPL, the system verifies unsigned component table entries associated with the signed component against the SCLAB contents, helping prevent malicious code from being injected during startup.
