Cryptography and information security are closely linked to each other. In what way? And what does cryptography mean? Read this post to find out.
What Is Cryptography?
It’s a method of protecting information and communications using codes. In this way, only those who have the right permission can read and process the information.
Additionally, in computer science, cryptography refers to secure information and communication techniques. Which are derived from mathematical concepts and algorithms. Which transforms messages in a way that is hard to decipher.
Cryptography And Information Security
As mentioned earlier, cryptography is closely linked to information security. How so? Cryptography has a role in information security. So let us discuss those roles.
Protecting The Information’s Confidentiality
One objective of cryptography is confidentiality. People with no permission cannot access the information transmitted. Thus only those with the right permission can access the information at all stages in its lifecycle.
Additionally, people’s personal information is stored in an organization’s system needs confidentiality. So encryption ensures the information remains secure while being stored and transmitted.
Note also, that even if there occurs compromising, the encrypted information is still useless for unauthorized individuals. Because they still need the right key for decryption.
Ensuring The Data’s Integrity
It refers to the accuracy of the information systems and their data. And a system that possesses integrity means that the movement and processing of data in the system are predictable. Additionally, that doesn’t change even when they process the data.
Thus, it’s cryptography that ensures the integrity of data. And that is by the use of algorithms and message digests. So the receiver can assure that he’s receiving genuine data. And not tampered with.
Ensures The Right Sender Or Receiver
Another objective of cryptography is making sure that the identity of both sender and receiver is correct. As well as the destination of the information. Which is the most important. In effect, secure communication is much easier.
Through Non-Repudiation, Both sender And Receiver Are Accountable
Non-repudiation is the confirmation of a transferred message. Either sent or received. Therefore, the sender cannot deny the fact that he or she sent the data. That is because cryptography uses digital signatures. Thus preventing the sender from denying the origin of the data.
Similarly, the receiver also cannot deny that he or she received the data.
Ensuring Data Availability
This guarantees that individuals with the right permission can use systems and retrieve data. Thus making the system reliable and accessible.
Cryptography Upholds Information Security With Powerful Cryptography Strategies
It’s a proven fact that information security is one of the biggest concerns. Most especially to businesses that operate competitively in this modern business environment. So, you need to execute the right strategies. Why?
That’s because in doing so, cryptography will help you safeguard the intellectual property. Thus helping you not to become victims of cyber threats and actors out there.
Today in the age of computerization, we face an increased risk of compromising our intellectual property. Thus, any organization needs strong cryptography in its information security.
