    Abstract: Various exemplary embodiments relate to a method, device, and storage medium including: receiving an NDEF message by an NFC device including a payload and at least one of a digital signature and a reference to a digital signature; stripping data from the payload to produce a stripped payload; verifying the payload using the digital signature and the stripped payload; and conditionally interpreting the payload based on whether the payload is verified. Various embodiments are described wherein: the payload includes a URI including a fragment denoted by a pound character; and stripping data includes stripping the fragment from the URI. Various embodiments are described wherein the payload is verified, the fragment comprises fragment data, and interpreting the payload comprises: transmitting a message requesting a resource identified by the URI, wherein the request omits the fragment data; executing a received script to transmit the fragment data to a device.

    Abstract: A portion of a reprogrammable storage device is used to implement permanent data storage. The storage device includes a plurality of electrically erasable memory elements and a controller. The plurality of electrically erasable memory elements are configured to store data. Each memory element is programmable a number of write cycles before reaching a write failure state. The controller is coupled to the plurality of memory elements. The controller includes a receiver and a write engine. The receiver receives an instruction to drive a selected memory element to the write failure state. The write engine repeatedly writes a data value, in a plurality of write operations, to the selected memory element until the write failure state of the selected memory element is established.

    Abstract: Disclosed is a method of generating a structure comprising at least one virtual machine, the method comprising: obfuscating a first virtual machine source code, thereby yielding a first obfuscated virtual machine (OVM) source code; associating a processor identifier with the first OVM source code, thereby yielding a processor-specific first OVM source code; compiling the processor-specific first OVM source code, thereby yielding a processor-specific first OVM. Furthermore, a structure generated by said method is disclosed.
