Appl. No.:

09/906811

Inventors:

David A. Pensak - West Chester PA
John J. Cristy - Landenberg PA
Steven J. Singles - Newark DE

Assignee:

Authentica, Inc. - Waltham MA

International Classification:

G06F 1130

US Classification:

713158, 713161, 713165, 713168, 713170

Abstract:

The invention provides for encrypting electronic information such as a document so that only users with permission may access the document in decrypted form. The process of encrypting the information includes selecting a set of policies as to who may access the information and under what conditions. A remote server stores a unique identifier for the information and associates an encryption/decryption key pair and access policies with the information. Software components residing on the authors computer retrieve the encryption key from the remote server, encrypt the information, and store the encrypted information at a location chosen by the author. A user wishing to access the information acquires the encrypted information electronically. Software components residing on the viewing users computer retrieve the associated decryption key and policies, decrypt the information to the extent authorized by the policies, and immediately delete the decryption key from the viewing users computer upon decrypting the information and rendering the clear text to the viewing users computer screen. The software components are also capable of prohibiting functional operations by the viewing users computer while the clear text is being viewed.

International Classification:

G06F 9/44

US Classification:

Abstract:

A method for regulating execution of an application program includes a process for preparing the application and a process for executing the application. The preparation process divides the application program into related segments and encrypts instructions of at least one segment, positions encrypted instructions in at least two discontiguous regions within an executable file, and associates header information with at least one discontiguous region. The execution process initiates execution of the protected application when at least a portion of the application instructions are available to the computer only in encrypted form. Also provided are systems and methods to allow debugging of code extensions to protected applications without sacrificing protection of the application. A Secure Debugger allows extension developers to examine memory and set breakpoints in their own extensions, without permitting them to view information in the rest of the protected application.
