Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
The termscryptologyandcryptographyare often confused or used synonymously, but they are not the same. Cryptology is a broad area that includes cryptography and cryptanalysis. It is derived from two Greek words:kryptósmeaning hidden andlógosmeaning word. Cryptography is about creating rules and regulat...
Symmetric encryption is a form of computerized cryptography using a singular encryption key to guise an electronic message. Its data conversion uses a mathematical algorithm along with a secret key, which results in the inability to make sense out of a message. Symmetric encrpytion is a two-way ...
What is multiprocessing? Multiprocessing is an umbrella term used to describe multiple CPUs working together either as part of a single computer system or distributed across multiple systems/devices. In most modern computers/servers/networks multiprocessing can take several forms including Symmetric Multipro...
meaning that the receiver is convinced of the origin of the message. To get these additional goals we often use a message authentication code (MAC), and the most widely used are those based on blockciphers and those based on hash functions (HMAC). Putting these two primitives together is ...
A VPN, which stands for "virtual private network,” is an app or service that encrypts the connection between your device and the internet, routing the data you send and receive through a secure VPN server. Imagine the internet as a kind of highway that you explore on a motorcycle. You...
Today, AES is one of the most popular symmetric key cryptography algorithms for a wide range of encryption applications for both government and commercial use. Some examples include the following: Data onstorage media, including hard drives and USB drives. ...
In other words, two halves make a whole. Let’s understand the meaning of halves with the help of everyday objects. Halves of Various Geometric Shapes Thetwo-dimensional shapesthat are symmetric can be divided into halves. That is, we will split them into two equal parts, the two parts ...
The working mechanism of symmetric DSL is completely different from that of asymmetric DSL technology. For symmetric digital subscriber lines, download and upload speeds are the same. Symmetric DSL splits the upstream and downstream frequencies evenly. SDSL is sometimes referred to as single-line digi...
The second section indicates that Joe has granted read access to PUBLIC (a special pseudo-role meaning everyone), while the third section shows that the Sales Team has been given INSERT, SELECT, and UPDATE privileges, also by Joe. Privilege flags in ACLs can vary significantly de...
