Abstract
To protect sensitive data in program code, a method includes providing a programming interface with a capability of allocating a protected region of memory which can only be accessed by authorized code. Sensitive data present in program code is stored in the protected region of memory. The method includes marking parts of code in a program as authorized or not authorized to access the sensitive data, and determining if that part of a program which is executing is authorized to access protected data by reference to the marking.
