An asymmetric cryptosystem is one where different keys are employed for the operations in the cryptosystem (e.g., encryption and decryption), and where one of the keys can be made public without compromising the secrecy of the other key.
WebApr 12, 2024 · The proposed cryptosystem is asymmetric in nature, so the private keys are depending on plaintext. If attackers able to reveals the keys of cryptosystem for a particular plaintext by applying chosen plaintext attack, then attacker unable to use the same keys to other plaintext as private keys changes in asymmetric cryptosystem. WebThe RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem -- a suite of cryptographic algorithms that are used for specific security services or purposes -- which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the internet.
