WebNov 25, 2024 · Cryptography is an automated mathematical tool that plays a vital role in network security. It assures the confidentiality and integrity of data as well as provides authentication and non-repudiation to the users. This chapter primarily focuses on cryptography techniques and their role in preserving the network security. WebElGamal cryptosystem can be defined as the cryptography algorithm that uses the public and private key concepts to secure communication between two systems. It can be considered the asymmetric algorithm where the encryption and decryption happen by using public and private keys.
