Latest Research Topics in Cryptography and Network Security

Network security term itself clearly depicts you that it is designed to protect the entire network from the authorized access in time of digital/analog data communication. The technologies used in network security are guaranteed to provide data confidentiality, authenticity, and availability against security risks throughout the communication.

This article is intended to display to you about latest research topics in Cryptography and Network Security with its current research areas!!!

Generally, the security mechanisms have two constituents to shield the network information. Below, we have listed the working principles of those constituents for your reference.

• • Add the security over the information. For instance, implement the encryption method over the transmitting message. So that information will be converted into a new unreadable format where the illegal user cannot access the original message until it is decrypted. Further, it also includes the code information in the header, which depends on the content of the message. Thus, it is used to detect/verify the original sender of the message.
  • In the case of sensitive data, it is necessary to share the information between only sender and receiver. The opponent party should not know the information under any conditions. In order to achieve this motive, the encryption key is used to convert the original plain text into scrambled text by the sender. Similarly, the decryption key is used to convert scrambled text into original plain text by the receiver.

  For any measure, the main goal is to identify and prevent security attacks with rescue abilities. Most probably, the security measures are based on cryptographic technologies. If you take any security mechanism, then you may find the trace of encryption / some kind of data transformation.

  

Overview of Cryptography and Network Security

Cryptography is basically classified into two major techniques, and they are cryptography and cryptanalysis. On the one hand, cryptography is the process of protecting or hiding the information through intelligent masking techniques (i.e., code the information). On the other hand, cryptanalysis investigates how the ciphertext is converted into plain text and vice-versa.

Due to its incredible security concern and contribution, it is largely used in many research domains and areas to improve its security aspects. Some of the current research aspects of cryptography are given as below,

• Hashing Techniques
• Public-Key Cryptography
• Key Distribution and Management
• Symmetric-Key Cryptography
• Real-time Cryptography Applications
• Cryptographic Security Protocols / Standards
• Emerging Cryptographic Techniques
  • Quantum Cryptography

  • And many more

Network Security is intended to develop various levels of shielding measures with an extended security scope. These measures are worked in the principle of identifying/predicting network security threats/risks to take immediate defensive response/actions. As a result, it protects the entire network information. The identification, prediction, and defensive response measures are essential to execute based on specific security policies. Few of the current research directions of the network security are given as below,

• Incident Response System
