Computer Security – Cryptography

There is a symbiotic relationship between cryptography and the development of high-performance computing systems. Modern-day computers were created at the behest of twentieth-century cryptanalysts. As the complexity of cryptographic systems progressed from mechanical to electronic systems, so did the need to develop more efficient methods to cryptanalyze them.

Cryptographic Module – Operator Authentication & Logical Interfaces

This post is part of the Computer Security – Cryptography posts series.
Operator Authentication
Authentication mechanisms could be demanded within a cryptographic module to authenticate an operator accessing the module and to verify that the operator is authorized to assume the requested role and execute services within that role. For Security Levels 2-5, a cryptographic module shall [...]

Operational Environments and OS Requirements for Modificable Operational Enviroments

This post is part of the Computer Security – Cryptography posts series.
Operational Environment
The requirements of this section apply only to modules containing software that run in a modifiable operational environment. The requirements do not apply to hardware only modules or anymodules with a non-modifiable operational environment.
The operational environment of a cryptographic module is the set [...]

The eyes of the sky shows the pollution

The pollution of air particles is measured, according to standards, at ground level. Unfortunately, many of the most polluted areas of the world, are in countries that currently are in developing process , which may not allow such complex monitoring . To address this problem, Sundar Chirstopher from the University of Alabama, used precisely those territories to collect data as a result of satellite measurements, and using conventional means, from the ground.

Spoke wrench

Spoke nipples are commonly T-shaped cross-sectional, with an inner thread running component of the direction through the hole that runs along the spoke nipple’s main axis. A spoke nipple stays in a hole drilled radially through the wheel’s rim, and the nipple is threaded onto the outer thread of a spoke. The spoke itself is rigid (fixed), at its other end, through a hole in the hub.

Protect your eyes with LG W53 series

Given that computer monitor is the main cause of deteriorating vision, LG offer users the new intelligent monitors from W53 series , which protect the eyes.

Intelligent monitor LG W53 offers enviable performance with regard to automatic settings according to the image on the screen. Monitor that have a background of white calls most eyes, therefore LG W53 diminishing brightness automatically during the drafting of documents.

Free antivirus from Microsoft

Microsoft will launch a free antivirus for PCs – code named Morro – which will be available on the company website. The product, which is found in beta and will compete with products
sold by Symantec and McAfee.

A Microsoft representative announced Wednesday that the software manufacturer is preparing to launch a antivirus, in beta, which can be downloaded free from the company website. Microsoft has stated that the product is still in testing stage and refused to give an exact date for release, stating only that it will take place “soon”.
