Baappay | What Is an Encryption?
Baappay | When using any sort of file backup service, encryption is as necessary as a component as any. Most companies use multiple forms of encryption to ensure protection of the data. Some of the companies offers, three layers of encryption to protect the data, files and material of companies using the service.
Computer encryption is based on cryptography, "the study of hiding information." Cryptography has been used throughout history as a way of coding information so that undesirable readers would not be able to interpret it. Spies, military leaders and diplomats rely on forms of cryptography to ensure that their communications remain hidden. Since the time of Caesar, rulers and leaders have been using various forms of cryptography to ensure the confidentiality of their information.
The process has obviously evolved considerably with the passage of time and modern cryptography involves the use of various technological tricks. Encryption is one of those tricks, so to speak. A file backup company uses encryption to ensure that information is safe, just like in the time of Julius Caesar.
But unlike the ciphers in Caesar's time, encryption in the modern era is incredibly sophisticated.
Computer encryption falls into two categories: symmetric-key encryption or public-key encryption.
Symmetric-key encryption is when two communicating computers share an "answer key." Each computer has a key (also known as a code) to encrypt the information sent between units. The keys are installed on each computer ahead of time by users, ensuring that the information is kept as safe as possible. Because of the complexity of the codes, modern symmetric-key encryption set-ups have an infinite combination of answer possibilities.
Public-key encryption doubles up the keys and utilizes a public and private code at the same time. The private key is only known to the host computer, while the public key is given to any computer the host computer wants to communicate with. This is almost a way of doubling back, providing an extra layer of security when compared to symmetric-key encryption.
Some of the service provider sites makes use of Secure Sockets Layer public-key encryption (128-bit) to ensure that security is taken as seriously as possible. Other encryption layers are also used, coding data and information behind several "walls" of protection.
Along with encryption, other techniques are often used to ensure the ultimate security of data. Techniques like a digital signature and message authentication code are used.
A digital signature is a mathematical equation designed to protect the integrity of a given message. This comes into play using asymmetric cryptography, with most forms of digital signatures using three algorithms (key generation, signing and signature verification) to triple "lock" the signature.
Baappay | A message authentication code (MAC) is a short piece of information that is used to authenticate a piece of information or a given message. This uses a secret key and a message to be authenticated and puts out a tag or MAC in return. The MAC protects the integrity of the message and information by allowing "verifiers" to detect changes to the message.
