Abstract: An apparatus and method for stabilized binary differencing are provided. The method includes obtaining a first report file for a first image corresponding to a current firmware version and a second report file for a second image corresponding to an updated firmware version, each report file containing information about a plurality of sections of the corresponding image, generating a first object array corresponding to the first report file and a second object array corresponding to the second report file, comparing the first object array to the second object array, updating the second object array to reflect the results of the comparison, generating a steering file based on the updated object array, performing a binary differencing on the first image and the second image based on the steering file, and generating a delta file based on the binary differencing.

Abstract: Techniques directed to an update package including a set of instructions used for, in a remote client device, creating a new data image from a base data image are provided. A method for generating an update package includes determining differences between a base data image and a new data image, generating COPY instructions corresponding to respective sections of code in the base data image, organizing the COPY instructions into a directed acyclic graph, performing cycle detection on the COPY instructions in the directed acyclic graph to detect any cycles, when a cycle is detected, identifying a COPY instruction in the detected cycle with a smallest overlapping part, removing the overlapping part from the identified COPY instruction, and generating a COPYBACK instruction including the overlapping part removed from the identified COPY instruction, and after all cycles have been detected, generating the update package based on the COPY and COPYBACK instructions.

Abstract: Methods, apparatuses, and computer program products for generating an update package based on a comparison between a base data image and a new data image, the update package including a set of instructions used for, in a remote client device, creating the new data image from the base data image, and for creating the new data image from the base data image based on the instructions included in the update package are provided.

Abstract: Methods and computer program products for generating an update package based on a comparison between a base data image and a new data image, wherein the update package includes a set of instructions used for, in a remote client device, creating the new data image from the base data image, are provided. One method includes determining, by a Binary Differencing Engine (BDE), differences between the base data image and the new data image, determining, by the BDE, whether to use at least one of a branch and call instructions, generating, by the BDE, a veneer when any of the at least one of a branch and call instructions exceeds a corresponding address range, each veneer including an address, associating, by the BDE, addresses of two or more veneers with a common update package instruction, and generating, by the BDE, the update package using one or more update package instructions and associated addresses.
