Temporal Key Integrity Protocol or TKIP was a stopgap security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware. This was necessary because the breaking of WEP had left Wi-Fi networks without viable link-layer security, and a solution was required for already deployed hardware. However, TKIP itself is no longer considered secure, a..
The Digital Signature Algorithm ( DSA) is a Federal Information Processing Standard for digital signatures. It was proposed by the National Institute of Standards and Technology (NIST) in August 1991 for use in their Digital Signature Standard ( DSS) and adopted as FIPS 186 in 1993. Four revisions to the initial specification have been released: FIPS 186-1 in 1996, FIPS 186-2 in 2000, FIPS 186-3 in 2009, and FIPS 186-4 in 2013.
Orthalicus reses, common name the Stock Island, Florida tree snail, is a species of large tropical air-breathing land snail, a tree snail, a terrestrial pulmonate gastropod mollusk in the family Orthalicidae. It was first described in 1830 by the United states Natural history Thomas Say. The holotype, a specimen probably collected in Key West, was subsequently lost. Over a hundred years later, in 1946, the American biologist Henry Augustus Pilsbry redescribed the species using a specimen from Stock Island...
A minor (abbreviated Am) is a minor scale based on A, with the pitches A, B, C, D, E, F, and G. Its key signature has no flats and no sharps (see below: Scales and keys). However the harmonic minor scale raises the G to G.
CryptoLocker is a ransomware trojan that targets computers running Microsoft Windows, believed to have first been posted to the Internet on 5 September 2013. CryptoLocker propagated via infected email attachments, and via an existing botnet; when activated, the malware Encryption certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the..

In computing, rebooting is the process by which a running computer system is restarted, either intentionally or unintentionally. Reboots can be either cold (alternatively known as hard) where the power to the system is physically turned off and back on again, causing an initial boot of the machine, or warm (alternatively known as soft) where the system restarts without the need to interrupt the power. The term restart is used to refer to a reboot when the operating system closes all programs and fina..
