CRYPTOGRAPHY2IntroductionWith the modernisation of technology and Internet-based services, the risk ofcybercrimes has grown significantly. People, companies, and government are under constantthreat of cyber-attacks. Cybercriminals attack over the personal and sensitive data such aspersonal information, banking details, and national security secrets. Hackers use thepopularity of social media websites and instant messaging application to collect the data ofpeople and organisations. Most corporations and governments use various methods ofsecurity to protect their data from hackers, such as antivirus, firewalls, and data-in-motion. Cryptography is another method of protecting data from hackers, cryptography in aGreek word which means secret writing. Cryptography is a method of coding and decodingmessages and data while transferring them, which protect the data from cloning by a hacker.If a corporation encrypts their data while transferring, then the receiver will require apassword or secret key to open such data. With the growth of cyber-attacks, the relevancy ofproper security mechanism is required for protection of data. The organisation can usecryptography to protect their data from hackers, but there are several problems in usingcryptography. This essay will focus on analysing the benefits of cryptography fromprotecting the data from cybercriminals. The essay will discuss the requirement ofcryptography and problems faced by organisations while using it as a security mechanism.Further, the essay will evaluate the role of cryptography in the future of data security.

CRYPTOGRAPHY3Role of Cryptography in Cyber SecurityThe popularity of social media and internet-based services has grown rapidly in past decade, billions of people use them daily to communicate, share and create new content. According to Vacca (2012), many of the modern corporations are conducting their business through online portals. Organisations use the internet and cloud-based services to store data online which can be easily accessible through various networks. On-line services provide various benefits to companies such as essay accessibility, faster transfer, communications through different channels and ease in payment. The government of various nations uses online services to store national secrets and perform other activities. The popularity of internet-based services raised the risk of cyber-attacks, hackers attack over the data of corporations and government to gain their secret information which shows the requirement ofa proper safety mechanism (Ling & Masao 2011).In 2016, more than 3.1 billion records leaked by the cybercriminals, most of these breaches include data from organisation such as MySpace, Minecraft, Tumblr, Wendy’s Co. and Payroll. According to Morgan (2016), as compared to 2015, the number of cyber-attacks has grown 40 percent in 2016. Many individuals, corporations, and government face risk of cyber-attack and breach of data from cybercriminals. The amount spent by worldwide organisations over cybersecurity-related hardware has risen from US$62.2 billion in 2015 to US$73.7 billion in 2016; these numbers are expected to grow more than US$90 billion in 2018 (Kharif 2017). Cybercriminals attack over the personal data of individuals such as social security number, banking information and other private details to siphon money out of their accounts. Cybercriminals collect sensitive data of government such as public data, government secrets or even nuclear codes, which can be dangerous for national security, proving the relevancy a security mechanism.Cryptography is a method of converting the data into gibberish which can only be understood by the person who has the secret key. According to Stallings & Tahiliani (2014), the requirement of cryptography has gained in the modern world but the use of Cryptography become popular during the World War I and II. To avoid leaking their conversations and secrets to enemy soldiers, the army uses secret codes to communicate and share important information between each other. The person receiving the message must require having the secret codes to understand the secret message. In World War II, armies started using modern
