Abstract: An object sharing system instantiates or defines an object container that can be cloned and return a reference to a “saved” object, allowing an object to be passed between applications while maintaining a consistent reference to the object. The object sharing system places a reference to an object in the object container. A serialization module serializes the object container; the serialized object container is passed to a second application comprising the object sharing system. A deserialization module in the second application deserializes the object container, instantiating an object container clone and extracting a reference clone. The reference clone allows the second application to manipulate the saved object as desired without further interaction with the first application.

Abstract: A trusted Java virtual machine provides a method for supporting tamper-resistant applications, ensuring the integrity of an application and its secrets such as keys. The trusted Java virtual machine verifies the integrity of the Java application, prevents debugging of the Java application, and allows the Java application to securely store and retrieve secrets. The trusted Java virtual machine environment comprises a TrustedDictionary, a TrustedBundle, an optional encryption method for encrypting and decrypting byte codes, and an underlying trusted Java virtual machine. The encrypted TrustedDictionary protects data while the TrustedBundle protects programming code, allowing applications to store secret data and secure counters. The application designer can restrict TrustedBundle access to only those interfaces that the application designer explicitly exports. The open source code may optionally be encrypted.
