What is WEP Encryption and its Security

WEP encryption (Wired Equivalent Privacy, or Wired Equivalent Privacy) is a cipher, implemented in the 802.11 wireless connection protocol, which encrypts the information we will pass between two points so that it can only be access to them and interpret them the points that have thesame key.
In general, a wireless router or Access Pointwill only allow access to those terminals that have the same WEP encryption key.
This key can be of three types:
64-bit WEP key .-, 5 characters or 10 hexadecimal digits (0 to 9””””A to F preceded by the string”0x”).
128-bit WEP key .-, 13 characters or 26 hexadecimal digits (0 to 9””””A to F preceded by the string”0x”).
256-bit WEP key .-, 29 characters or 58 hexadecimal digits (0 to 9””””A to F preceded by the string”0x”).
The one most often used is 128 bit, offering a good level of protection without being overly long and complicated.
The 256-bit WEP encryption is not supported by many devices.
A WEP key can decipher (there are programsfor it), but this requires an uninterrupted traffic data for a given time (in fact, enough data and enough time).
Obviously, the higher the level of encryptionand key more complicated the more difficult it will be to decipher.
It does not take the same (given data volume and time) to crack the WEP encryption key of 64 bits of 128 bits, and there are also no relationship between arithmetic, ie it does not take twice as cracka WEP key of 128 bits a 64-bit.
Although it is possible to crack these encryption keys, do not think that is easy orquick. A good key 128-bit WEP encryption (if not a 256-bit) can be almost unreadable if we have ensured that is sufficiently complicated.
Most key-cracking programs are based on a series of more or less logical sequence with which it begins to attack our system to enter. Obviously, a key rate takes seconds 1234567890 be located, but no one thinks (or should it occur) to this key.
We should avoid keys that contain sequences related to us (dates, names, places), and phrases, as it is the first thing you try this type of program. This is not only valid for a WEP key, but for any kind of key you say. We should also avoid key easy as consecutive sequences of keys or numbers.
For safety it is strongly recommended wherever possible to enable MAC address filtering.
A MAC (Media Access Control address) is a hexadecimal identifier of 48 bits. This address is unique for each device, not beinga user-modifiable parameter (each card or network interface has its own MAC address, set by the manufacturer.)

Turn Android Phone to Ubuntu Desktop Using Ubuntu for Android


Ubuntu for Android bring desktopto your android device. Use Android on the phone and Ubuntu as your desktop, both running simultaneously on the same device, with seamless sharing of contacts, messages and other common services. Canonical unveiled Ubuntu for Android, bringing the world’s favourite free desktop experience to multi-core Android smartphones docked with a keyboard and monitor.
The phone experience is pure Android – it’s anormal Android phone. When the device is connected to a computer screen, however, itlaunches a full Ubuntu desktop on the computer display. It’s exactly the same desktop used by millions of enterprise and home users on their Ubuntu PCs, and includes hundreds of certified applications, from office productivity to photography, video and music.
All data and services are shared between theUbuntu and Android environments, which run simultaneously on the device. So Android applications such as contacts, telephony and SMS/MMS messaging are accessible from the Ubuntu interface. Indeed, all data on the smartphone can be accessed at any time, docked or not.
Ubuntu for Android gives mobile workers a company phone that is also their enterprise desktop. Government and private institutions have embraced Ubuntu on the desktop because of its ease of use, security, manageability, superb range of native applications and excellent support for web browsers like Chrome and Firefox. The desktop can also include Windows applications, using thin client and desktop virtualisation tools. Today’s IT departments commonly support a PC and at least one desktop phone for every employee. Many also provide and manage mobile phones. Ubuntu for Android presents a compelling solution to IT complexity by reducing that burden to a single device.
Mark Shuttleworth said:
“The desktop is the killer-app for quad-core phones in 2012. Ubuntu for Android transforms your high-end phone into your productive desktop, whenever you need it”
