4.2. Software Update Process


Software Update Process - part 2


Software update process involves two files

    • First file is called the source file, old file or initial file.
    • The second file is usually called target file, new file or destination file.


There are two transforms that involve the two files.

    • The binary diff file creation (also called delta or patch). We call this process or transform, SecureENCODE. See more here.
    • The patching of the source file into becoming bit-by-bit identical to the target file. We call this process or transform, SecureDECODE. See more here.
