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. // Verify the assemblies foreach (var entry in zipArchive
The following is an example of a XAP archive verification tool: When a XAP archive is installed on a
// Verify the signature var signature = new SignatureDescription(); signature.KeyAlgorithm = certificate.PublicKey.KeyAlgorithm; signature.DigestAlgorithm = "SHA256";
using System; using System.IO; using System.Security.Cryptography; using System.Security.Cryptography.X509Certificates;
Future work includes implementing and testing our proposed framework, as well as exploring additional security measures to protect Windows Phone devices from malicious applications.
