organizations worldwide use cryptography in different ways
Most organizations worldwide use cryptography in different ways to ensure they have enough protection for their data. Cryptography is a method of writing and storing data in a way that can only be accessed by those who need it and hide it from others for security reasons. Companies use cryptography to ensure there is secrecy in their data storage. Storage encryption is the application of cryptographic styles on information while in storage files. Confidentiality in storage is kept by storing data in coded forms. Organizations design their computer systems in a way that a user has to provide at the beginning of a session to get access to the information. The system itself ensures there are proper encryption and decryption throughout the period in use. Other companies have some hardware devices that are used in personal computers to encrypt the data in the disk. The data can only be accessed when an individual provides the right key; otherwise the information will be useless when an individual steals it (Kim, 2016). This approach helps companies to protect their data against potential threats such as hacking, which might cost them a great loss.
Cryptography is used by companies to ensure that there is integrity in transmission. Businesses should ensure that their data is not altered and changed during transmission; this happens mostly in electronic fund transfer, which needs high integrity. Cryptography measures should be employed to stop accidental and deliberate variation of information during transmission by ensuring there is a proper checksum before and after the transfer. The data received should be checksummed then decrypted with the fast checksum to ensure they information match, and there is no alteration. The best way is to employ the use of public-key to encrypt the data (Jawaharlal, Narayanan, Santhar, and Sivaramalingam, 2019). This method makes it hard to invert data; companies use this approach to protect their customer’s details from getting hacked by cybercriminals who have intentions of stealing. Organizations also used cryptography in integrity storage; this measure is achieved through the use of an access control system whereby only people with the right credentials are allowed to access data. There are some regions in companies that are restricted, and limited people are allowed to enter since there is confidential information that is critical to the organization. There should be a proper checksum of data to ascertain its validity since there are attacks such as computer viruses that can tamper with the information.
Companies use cryptography to ensure there is proper authentication of identity. Through authentication, a user verifies his or her credentials before accessing data. This is through the use of passwords, which are set by organizations. The firms have modern systems which use cryptographic transforms together with other features of the user to get an effective validation of identity. The advantage of using this approach is that most passwords are found in encrypted forms; this makes it hard for a different person who does not know the password to access the system. The passwords are not stored in text forms; there are also strong passwords that the individuals use, which are hard to guess, therefore, preventing people with bad intentions to access organizational data. Companies ensure that they create boundaries by limiting their employees from accessing certain areas with confidential information. This approach ensures that there is enough security, and no one can access the system illegally.
