Two hand-written documents were found in the pockets of murder victim Ricky McCormick when his body was discovered in a field in St. Charles County, Missouri on June 30, 1999. Attempts by the FBI's Cryptanalysis and Racketeering Records Unit (CRRU) and the American Cryptogram Association failed to decipher the meanings of those two coded notes, which are listed as one …

Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume.It is used to prevent unauthorized access to data storage. The expression full disk encryption (FDE) (or …

FTPS (also known as FTP-SSL and FTP Secure) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and, formerly, the Secure Sockets Layer (SSL, which is now prohibited by RFC7568) cryptographic protocols.. FTPS should not be confused with the SSH File Transfer Protocol (SFTP), a secure file …

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across connections. Types of connections include DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as less popular or now deprecated …

A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ().In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit is dependent on the current state of the cipher, it is also known as state …

A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. The benefits of a VPN include increases in functionality, security, and management of the private network.It provides access to resources …

The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.. EFS is available in all versions of Windows except the home versions (see Supported operating …

Disk encryption is a special case of data at rest protection when the storage medium is a sector-addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. For an overview, see disk encryption.For discussion of different software packages and hardware devices devoted to this problem, see disk encryption software and disk encryption hardware

Structure of the troposphere Composition. In the Earth’s planetary atmosphere, a volume of dry air is composed of 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, trace gases, and variable amounts of water vapor.The sources of atmospheric water vapor are the bodies of water (oceans, seas, lakes, rivers, swamps), and vegetation on the planetary …
