Abstract
Embodiments provide bidirectional signature protection for packaged apps by verifying an authored app as executable and downloadable from a trusted marketplace service in response to determining that a (first) unique signature embedded within binary code defining the authored app matches an original trusted marketplace service signature acquired from the trusted marketplace service. Embodiments store another (second) signature acquired from the binary code defining the authored app into a storage item of the trusted marketplace service, wherein the second signature is unique to the authored app and different from the first signature; and offer the verified, authored app for download from the trusted marketplace service, wherein the first signature and the second signature are embedded in binary code defining the authored app.
