Salvează Pământul ! Salvează specia umană ! Trezeşte-te !
În ultimii 20 de ani, dovezile faptului că activitatea umană influenţează climatul şi natura într-un mod irevocabil s-au acumulat.Peste tot în mass-media periodic apar ştiri despre cutremure,alunecări de teren,inundaţi, uragane şi alte diverse catastrofe naturale.Pământul se revoltă împotrivă acţiunilor distrugătoare ale speciei umane. Peste tot apar studii emise de diferite organizaţii guvernamentale,nonprofit,de oameni de ştiinţă, [...]
Mobile Security – Smartphones and PDAs Articles
A summary of posts about Mobile Security – Smartphones and PDAs.
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 [...]

Software
SECURITY LEVEL 1
The succeeding necessities shall implement to software contained within a cryptographic module for this level of security.
All cryptographic code within the module shall be in executable form.
A cryptographic mechanism utilizing an authorized integrity technique (for instance, an aapproved message authentication code [...]
Multiple-Chip Standalone and Embeded Cryptographic Modules
This post is part of the Computer Security – Cryptography posts series.
Standalone
SECURITY LEVEL 1
In plus to the necessities for Security Levels 1 and 2, the succeeding necessities shall implement to multiple-chip standalone cryptographic modules for this level of security.
The multiple-chip embodiment of the circuitry within the cryptographic module shall be covered with a hard potting [...]
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.
Economic crisis is good for environment
Seems bizarre, but according to news published recently in Western media, the environment would have to gain from the economic crisis. How ?
The policy of the president of the United States, Barack Obama, to help people to overcome the crisis has been defined by many analysts as a sort of a “New Green Deal”.
