Discuss how and why companies use cryptography.

Answer 1

Answer-

Before the information technology era, cryptography still existed. Cryptography, therefore, has been and continues to be very crucial to individuals and organizations that aim at maintaining the secrecy of their information. Cryptography was used in the past by government agencies and other institutions to preserve the confidentiality of communications among military leaders and government spies. Following the recent technological inventions, cryptography is now used in businesses and other companies as an information management tool to maintain the confidentiality of specific issues. Today, companies and businesses use cryptography in different ways and for various purposes. This depends on their functionalities and needs.
Authenticate identities
In many companies, cryptography is used in the access control systems to verify the identity of different individuals as they move in and out of the institution. It functions just like passwords whereby somebody has to confirm the authenticated access. Most companies today use modern cryptography along with their characteristics to ensure an efficient authentication system. Also, encrypting passwords ensure that unauthorized persons cannot access restricted areas.
Securing communications
Companies often involve many voice and message conversions within their environments. Most of these conversations are confidential, and the public is not expected to access them. Therefore, most companies secure their communications through cryptography by encrypting links and coding all the transmitted messages among company officials. This makes it difficult for invaders to access any content or information communicated within the organization. This is achieved by scrambling all text messages. Cryptography is also used by companies to secure their voice conversations occurring through telephones. This is done through encrypting the calling links between individuals in the organization and encryption links them to talk without divulging this to the public.
Securing data transmission and storage
Different companies vary from one to another depending on the services they offer, the goods they provide, or their marketing strategies. This, therefore, shows that the companies must ensure the security of the information they own and ensure that there are no leakages that can result in unintended and unauthorized access to their data. Through cryptography, companies can share and exchange information internally without any doubts that it would leak to the public.  Also, the different cryptographic systems used by the companies encrypt their data and ensure it is stored in a way that it cannot spill to unauthorized persons even in case of hacking occurs.
Securing digital signatures
Digital signatures are digital codes that are generated and authenticated by the public key encryption system attached to the electronic documents od a company to verify the identities of the sender and recipient. Digital signatures help companies have independent electronic communications since they vary from one company to another. With the current technological advancements, digital signatures serve a great purpose in identifying fake communications and organizational messages.
