Hardware Backdoor
Hardware backdoors are backdoors in hardware, such as code inside hardware or firmware of computer chips. The backdoors may be directly implemented as hardware Trojans in the integrated circuit. Hardware backdoors are intended to undermine security in smartcards and other cryptoprocessors unless investment is made in anti-backdoor design methods. They have also been considered for car hacking. Severity Hardware backdoors are considered highly problematic because: # They can’t be removed by conventional means such as antivirus software # They can circumvent other types of security such as disk encryption # They can be injected at manufacturing time where the user has no degree of control Examples * Around 2008 the FBI reported that 3,500 counterfeit Cisco network components were discovered in the US with some of them having found their way into military and government facilities. * In 2011 Jonathan Brossard demonstrated a proof-of-concept hardware backdoor called "Rak ...

Backdoor (computing)
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer" —a tiny computer-within-a-computer such as that found in Intel's AMT technology). Backdoors are most often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems. From there it may be used to gain access to privileged information like passwords, corrupt or delete data on hard drives, or transfer information within autoschediastic networks. A backdoor may take the form of a hidden part of a program, a separate program (e.g. Back Orifice may subvert the system through a rootkit), code in the firmware of the hardware, or parts of an operating system such as Windows. Trojan horses can be used to create vulnerabilities in a device. A Trojan horse may appear to be an entirely leg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Verifiable Computing
Verifiable computing (or verified computation or verified computing) enables a computer to offload the computation of some function, to other perhaps untrusted clients, while maintaining verifiable results. The other clients evaluate the function and return the result with a proof that the computation of the function was carried out correctly. The introduction of this notion came as a result of the increasingly common phenomenon of " outsourcing" computation to untrusted users in projects such as SETI@home and also to the growing desire of weak clients to outsource computational tasks to a more powerful computation service like in cloud computing. The concept dates back to work by Babai et al., and has been studied under various terms, including "checking computations" (Babai et al.), "delegating computations", "certified computation", and verifiable computing. The term ''verifiable computing'' itself was formalized by Rosario Gennaro, Craig Gentry, and Bryan Parno, and echoes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York University Tandon School Of Engineering
The New York University Tandon School of Engineering (commonly referred to as Tandon) is the engineering and applied sciences school of New York University. Tandon is the second oldest private engineering and technology school in the United States. The school dates back to 1854 when its predecessor institutions, the University of the City of New York School of Civil Engineering and Architecture and the Brooklyn Collegiate and Polytechnic Institute, were founded. The school was renamed in 2015 in honor of NYU Trustees Chandrika Tandon, Chandrika and Ranjan Tandon following their donation of $100 million to the school. The school's main campus is in Brooklyn's MetroTech Center, an urban academic-industrial research park. It is one of several engineering schools that were founded based on a European History of European research universities, polytechnic university model in the 1800s, in response to the increasing Technological and industrial history of the United States, industrial ...

Bloomberg Businessweek
''Bloomberg Businessweek'', previously known as ''BusinessWeek'', is an American weekly business magazine published fifty times a year. Since 2009, the magazine is owned by New York City-based Bloomberg L.P. The magazine debuted in New York City in September 1929.

IPhone 5C
The iPhone 5C (marketed as iPhone 5c) is a smartphone that was designed and marketed by Apple Inc. It is part of the sixth generation of the iPhone. The device was unveiled on September 10, 2013, and released on September 20, 2013, along with its higher-end counterpart, the iPhone 5S. The "c" in the iPhone 5c's name stands for Color. The iPhone 5C is a variant of the iPhone 5, with similar hardware specifications but a hard-coated polycarbonate shell instead of the aluminum of the original iPhone 5. The iPhone 5C was available in several color options and shipped with iOS 7. The iPhone 5C was released at a lower price point than the new flagship 5S; unlike Apple's usual practice of lowering the price of the previous model upon release of a new version, the iPhone 5 was explicitly discontinued and replaced by the 5C. On September 9, 2014, the 16 and 32 GB iPhone 5C models were replaced by the 8 GB model upon the announcement of the iPhone 6 and 6 Plus. On ...

NAND Flash Memory
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs. They differ at the circuit level depending on whether the state of the bit line or word lines is pulled high or low: in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire device. NOR flash memory allows a single machine word to be written to an eras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tailored Access Operations
The Office of Tailored Access Operations (TAO), now Computer Network Operations, and structured as S32, is a cyber-warfare intelligence-gathering unit of the National Security Agency (NSA). It has been active since at least 1998, possibly 1997, but was not named or structured as TAO until "the last days of 2000," according to General Michael Hayden. TAO identifies, monitors, infiltrates, and gathers intelligence on computer systems being used by entities foreign to the United States. History TAO is reportedly "the largest and arguably the most important component of the NSA's huge Signals Intelligence Directorate (SID), consisting of more than 1,000 military and civilian computer hackers, intelligence analysts, targeting specialists, computer hardware and software designers, and electrical engineers". Snowden leak A document leaked by former NSA contractor Edward Snowden describing the unit's work says TAO has software templates allowing it to break into commonly used hardwa ...

Edward Snowden
Edward Joseph Snowden (born June 21, 1983) is an American and naturalized Russian former computer intelligence consultant who leaked highly classified information from the National Security Agency (NSA) in 2013, when he was an employee and subcontractor. His disclosures revealed numerous global surveillance programs, many run by the NSA and the Five Eyes intelligence alliance with the cooperation of telecommunication companies and European governments and prompted a cultural discussion about national security and individual privacy. In 2013, Snowden was hired by an NSA contractor, Booz Allen Hamilton, after previous employment with Dell and the CIA. Snowden says he gradually became disillusioned with the programs with which he was involved, and that he tried to raise his ethical concerns through internal channels but was ignored. On May 20, 2013, Snowden flew to Hong Kong after leaving his job at an NSA facility in Hawaii, and in early June he revealed thousands of clas ...
