Understanding Data Encryption Techniques for Better Security

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

For as long as modern computers have been around, they have been associated with encryption in one way or another. It is no coincidence that the first semi-programmable computer, Colossus, was developed to decrypt messages during the Second World War. Encryption relies on encoding information in a way that makes it difficult to decode without either a key (cipher) or an awful lot of mathematical muscle. The longer the length of the cipher (in bits), the more difficult it will be to break. Although there are many encryption techniques that are unbreakable in practice, there are very few that are unbreakable in theory, given enough time or processing power.

Exploring Quantum Cryptography's Impact On Secure Data Exchange

Quantum cryptography – using a private communication channel to lock down the exchange of sensitive data between two points – has to date created much more discussion than it has practical applications. However, with scientists, researchers and academics already on the case, it could be just five years until the technology hits the mainstream.

Driving Research and Standards at RSA Security With Burt Kaliski

WHEN budgets get tight, R&D is often one of the first departments to feel the squeeze. But at RSA Security, vice-president of research Burt Kaliski and his team are considered the heart and soul of the business. RSA puts about 18-20 per cent of its revenue into applied research and standards development at its research centre, RSA Laboratories.

Innovative Hacker-Proof Network Development Amidst Quantum Threats

In Cambridge, Mass., not too far from the Charles River, which cuts near Harvard and M.I.T., David Pearson is attempting to build an un-hackable network. Pearson is a division scientist at BBN Technologies, a private research company in Cambridge, Mass., which is most famous for building, in 1969, the first few nodes of a computer network connecting its headquarters to Harvard University and Boston University that over time would evolve into the Internet. Now the firm has built a network it says is impervious to hackers.

Bruce Schneier and Counterpane's Success in Cybersecurity Services

Bruce Schneier, founder and chief technical officer of Counterpane Internet Security, might be as close as the computer security industry gets to its own celebrity. Although not as well known as Larry Ellison at Oracle or Bill Gates at Microsoft, Schneier is still the public face of his company, recognized by industry insiders as one of their gurus. Businesses hire Counterpane to guard their networks from hackers and viruses in the same way a nervous homeowner would pay a home-security provider like ADT to watch for fires or burglars.

Innovative CS2 Block Cipher Boosts Security and Efficiency

In this paper we describe our new CS2 block cipher which is an extension of the original CS-Cipher. Our new design inherits the efficiency of the original design while being upgraded to support a larger block size as well as use a slightly improved substitution box. We prove that our design is immune to differential and linear cryptanalysis as well as argue it resists several other known attacks.

Risks to Data Integrity and Authentication Due to SHA-1 Vulnerabilities

In a three-page research note, three Chinese scientists -- Xiaoyun Wang and Hongbo Yu of Shandong University and Yiqun Lisa Yin, a visiting researcher at Princeton University -- stated they have found a way to significantly reduce the time required to break a algorithm, known as the Secure Hashing Algorithm, or SHA-1, widely used for digital fingerprinting data files. Other cryptographers who have seen the document said that the results seemed to be genuine.

Research Team Identifies Serious SHA-1 Flaw in Digital Signatures

Security experts are warning that a security flaw has been found in a powerful data encryption algorithm, dubbed SHA-1, by a team of scientists from Shandong University in China. The three scientists are circulating a paper within the cryptographic research community that describes successful tests of a technique that could greatly reduce the speed with which SHA-1 could be compromised.

Progress in Quantum Communication Using Entangled Photons

Ultimately cryptographers want some form of quantum repeater--in essence, an elementary form of quantum computer that would overcome distance limitations. A repeater would work through what Albert Einstein famously called "spukhafte Fernwirkungen," spooky action at a distance.

Gilles Brassard and Charles Bennett: Pioneers Who Transformed Cryptography

It began 25 years ago in the warm coastal waters of Puerto Rico when a stranger swam over to Gilles Brassard and struck up a conversation about using quantum physics to make bank notes impossible to counterfeit. "I had no idea who he was," recalled Brassard, then a 24-year-old prodigy and computer-science professor at the Universite de Montreal. "He just started talking nonsense about quantum physics."

Federal Agencies Adopt SHA-256 For Enhanced Cryptographic Security

Federal agencies have been put on notice that National Institute of Standards and Technology officials plan to phase out a widely used cryptographic hash function known as SHA-1 in favor of larger and stronger hash functions such as SHA-256 and SHA-512.

Quantum Computing Advances Impact Encryption And Financial Systems

Quantum computing is set to revolutionise the way we work. Trouble is, it could crack any of today's security codes in a fraction of a second, says Charles Arthur.When bankers and spies begin to worry about advances in computing, the rest of us would do well to take notice. What makes them edgy are the advances being made in "quantum computing", which is, as might be expected from the name, as entangled and confusing a field to understand as the branch of physics on which it is based - quantum mechanics.

Improving Security for Limited Devices Using Elliptic Curve Cryptography

Adding security to constrained devices is not an easy task for developers who need to accommodate a range of new features without compromising usability. Experience has shown that building security in at the design stage yields better results from a security and performance perspective. Therein lies the challenge. It’s no secret that most cryptographic systems are computationally taxing. Such is not the case with Elliptic Curve Cryptography, or ECC, which has the most strength per bit of any known public key system today and consequently is ideally suited for resource-constrained devices.

Unlocking Email Security: Challenges of Public Key Cryptography

With its ability to authenticate, digitally sign, and encrypt messages, public key cryptography seems like a natural fit for protecting e-mail: With one solution, you can ensure the integrity of the content and prove the identity of the sender. But public key cryptography is akin to peace in the Middle East--everyone agrees it's a good idea, but the associated complexities can derail implementation. . . .

Understanding DES's Role in 3DES Security and Design Choices

The deeply embedded crypto algorithm lives on in 3DES, but that standard demands careful design and informed choices.You have only until Sept. 9 to object to the federal government's proposed decertification of the Data Encryption Standard. After reading the proposal, I'm tempted to complain that it would not leave DES sufficiently dead. . . .
