An extension of the Media Transfer Protocol (MTP) may enable marking and/or identifying objects comprising public keys and/or security certificates with object properties. The object properties may identify the objects and/or specify a source of the objects. The objects and object properties may be stored and/or communicated to and/or from a device that supports MTP communications. The communication may occur during initiation of communication between the devices and/or in a response to a request for information. For example, MTP operations GetObjectPropDesc or GetObjectPropValue and corresponding responses ObjectPropDesc dataset or a current value may be utilized. A public key and/or security certificate object may be marked with regard to identity and/or source and the marked information may be communicated via MTP. In this regard, MTP communication may be secured based on one or more MTP objects and/or object properties.
