The **ElGamal** signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms. It was described by Taher **ElGamal** in 1984. The **ElGamal** signature algorithm described in this article is rarely used in practice. A variant developed at NSA and known as the Digital Signature Algorithm is much more widely used.

I am having a trouble not knowing how to do a java code that will take user string then encrypt it using **Elgamal** algorithm as following. **Elgamal** algorithm Pseudo code: Select Q where Q is a prime number. Select α where α is a primitive root of Q and α < Q. Select Random Xa such that Xa < Q -1. Calculate Ya , such that Ya = αXa. **ElGamal** Encryption Algorithm. The **Elgamal** encryption scheme is an asymmetric key encryption algorithm which consists of three phases (i.e., key generation, encryption, decryption). It is based on the Diffie-Hellman key exchange and defined over a cyclic group $ G $. Therefore, its security relies heavily on Discrete-log based building blocks. **ElGamal** Public Key Cryptosystem. Open Live Script.

Not everything you say needs to be heard by everyone else around you, and this goes quite. El-**gamal** digital signature scheme: This scheme used the same keys but a different algorithm. The algorithm creates two digital signatures, these two signatures, are used in the verification phase. The key generation process is the same as that of EI-**gamal** algorithms. The public key remains ( e 1, e 2, p) and the private key continues to be d. **ElGamal** signature scheme Author: Devon Ritter Created Date: 3/11/2011 5:45:20 PM. 1. “Rabin Cryptosystem is a variant of the **Elgamal** Cryptosystem” a) True b) False. Answer: b Clarification: Rabin Cryptosystem is a variant of the RSA Cryptosystem. 2. Using Rabin cryptosystem with p=23 and q=7 Encrypt P=24 to find ciphertext. The Cipher text is a) 42 b) 93 c) 74 d) 12. Answer: b Clarification: **Calculate** n = p × q = 161. **Calculator** Use. Calculate a mod b which, for positive numbers, is the remainder of a divided by b in a division problem. The modulo operation finds the remainder, so if you were dividing a by b and there was a remainder of n, you would say a mod b = n.. How to Do a Modulo Calculation. The modulo operation finds the remainder of a divided by b.To do this by hand just divide two numbers and note. Another way of **calculating** 'L' is to list of numbers from 1 to N, remove numbers which have common factor which N and count the remaining numbers. E: encryption key: Find a number between 1 and L that is coprime with L and N. D: decryption key: D * E mod L = 1: Remainder of the product of D and E when divided by L should be 1 (D * E % L = 1). Here you can calculate how many camels your girlfriend or boyfriend is worth.
