A XAP archive is a signed package that contains a manifest file (WMAppManifest.xml) and one or more assemblies (DLLs or EXEs). The manifest file contains metadata about the application, such as its name, version, and permissions. The assemblies contain the application's executable code. When a XAP archive is installed on a Windows Phone device, the operating system verifies the archive's digital signature to ensure its authenticity and integrity.
Windows Phone is a popular mobile operating system developed by Microsoft. Windows Phone applications are packaged in XAP archives, which are essentially ZIP files containing the application's executable code, resources, and metadata. XAP archives are used to distribute and install applications on Windows Phone devices. However, the open nature of the Windows Phone marketplace and the ease of creating and distributing XAP archives raise concerns about the security and integrity of these applications. windows phone xap archive verified
// Verify the signature var signature = new SignatureDescription(); signature.KeyAlgorithm = certificate.PublicKey.KeyAlgorithm; signature.DigestAlgorithm = "SHA256";
// Verify the assemblies foreach (var entry in zipArchive.Entries) // Read the manifest file using (var manifestStream
Future work includes implementing and testing our proposed framework, as well as exploring additional security measures to protect Windows Phone devices from malicious applications.
