Plaintext is what you want to protect; ciphertext should appear to be random gibberish. The design and analysis of today’s cryptographic algorithms is highly mathematical. Do not try to design your own algorithms.

WebAsymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys -- one public key and one private key -- to encrypt and decrypt a message and protect it from unauthorized …
WebMar 22, 2024 · ElGamal encryption is a public-key cryptosystem. It uses asymmetric key encryption for communicating between two parties and encrypting the message. This cryptosystem is based on the difficulty of finding discrete logarithm in a cyclic group that is even if we know g a and g k, it is extremely difficult to compute g ak. WebElGamal encryption consists of three components: the key generator, the encryption algorithm, and the decryption algorithm. Key generation [ edit] The first party, Alice, generates a key pair as follows: Generate an efficient description of a cyclic group of order with generator . Let represent the identity element of . Choose an integer
