A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Secure data parser method and system

Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.

Method and apparatus for coupling an antenna to a device

A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules.

Backhaul link for distributed antenna system

A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

Remote distributed antenna system

A method and system extends a secret bit string to safeguard the secret. In one embodiment, the method comprises adding a secret bit string of length s to a product of two random bit strings using arithmetic defined for polynomials over GF(2) to produce an extended bit string. The extended bit string has a length m that is longer than s. A total of n shares are generated from the extended bit string, of which at least k shares are needed to reconstruct the secret bit string. The n shares are distributed to a plurality of cooperating computing entities for secret sharing.

Extending a secret bit string to safeguard the secret

A compiler is loaded by a computing device using an evaluation function that is included in a program in a compiled form. The evaluation function causes the compiler to compile source code for the program, wherein the source code includes new instructions that are uncompiled, and wherein compiling the source code generates compiled code that includes the new instructions. The evaluation function loads the compiled code into memory, retrieves the new instructions, and executes the new instructions. The evaluation function may perform these operations during runtime of the program that includes the evaluation function.

Dynamic compiling and loading at runtime

In one embodiment, a mechanism for generating pseudo-random number sequences is disclosed. In one embodiment, a method includes receiving seed values for a pseudorandom number generator (PRNG) in a computing system, the seed values being polynomials. The method further includes running the PRNG using the seed values as initialization parameters, the running including performing operations of the PRNG over GF(2n), and generating a sequence of pseudorandom numbers.

Mechanism for generating pseudorandom number sequences

Some embodiments of a method and an apparatus to migrate functionalities across systems have been presented. In one embodiment, a system call from an application running on a first system is detected. The first system has a first version of an operating system, but the system call requires a functionality that is not available in the first version of the operating system. The functionality is available in a second version of the operating system running on a second system. Therefore, the system call is reflected from the first system to the second system.

Method and an apparatus to migrate functionalities across systems

The use of callback functions when executing intermediate instructions in a virtual machine is described. The virtual machine receives and evaluates intermediate instructions. The virtual machine evaluates the instructions based on a function table referencing definitions of the functions. A callback is loaded into the virtual machine platform, and a callback loader modifies the function table to cause a function in the table to point to the callback instead of the standard definition. Thus, when the intermediate code is evaluated, it is evaluated based on the modified functionality of the callback rather than the standard definition.
