| 20110214179 | SECURE METHOD AND SYSTEM FOR COMPUTER PROTECTION - Attacks by computer viruses, worm programs, and other hostile software (‘malware’), have become very serious problems for computer systems connected to large communication networks such as the Internet. One potential defence against such attacks is to employ diversity—that is, making each copy of the attacked software different. However, existing diversity techniques do not offer sufficient levels of protection. The invention provides an effective diversity solution by applying tamper resistant software (TRS) encoding techniques, to the communications that take place between software components, with corresponding changes to the code handling those communications. These communications may include, for example, data passed between software routines via parameters or mutually accessible variables, light-weight messages, signals and semaphores passed between threads, and messages passed between software processes. Effective TRS encoding techniques include data-flow encoding and mass-data encoding techniques. | 09-01-2011 |
| 20110093937 | AUTHENTICATED DATABASE CONNECTIVITY FOR UNATTENDED APPLICATIONS - A custom database connectivity component is deployed in conjunction with a native database connectivity component and a credential manager. The custom connectivity component has a requestor interface for communicating with a requestor application, a credential service interface for communicating with the credential manager, a native database connectivity interface for communicating with native connectivity components, and a decision engine for determining how to convert a request from a requestor to an appropriate API call to the credential manager. The custom connectivity component provides an authenticated and authorized database connection for a requestor application. The component transparently serves retrieves database, or other target resource, credentials on a real time basis, without requiring code changes to the requestor application. | 04-21-2011 |
| 20110067012 | SYSTEM AND METHOD FOR GENERATING WHITE-BOX IMPLEMENTATIONS OF SOFTWARE APPLICATIONS - A development suite for generating files, such as DRM-protected files, using white-box cryptography. The suite consists of a code generation tool, a data transformation engine, and a white-box data generation tool, and a white-box library. In the white-box cryptography context, the data transformation engine is used to protect the boundary between the cryptographic operation and the surrounding code. In particular, the data transformation engine is used to apply data transformations to the inputs to and outputs from the cryptographic operations. If the user specifies that transformations are required via a white-box parameterization file, the code generation tool puts the information specified by the user into a form the data transformation engine understands, namely as qualifiers on data variables and function prototypes. The data transformation engine then applies the specified transformations, and passes information to the data generation tool regarding which transformations were chosen. | 03-17-2011 |
