Modified El Gamal algorithm for multiple senders and single receiver encryption
Aris J. Ordonez, Ruji P. Medina, Bobby D. Gerardo · 2018
This paper presents a modification of the ElGamal Encryption Algorithm which allows multiple senders to encrypt a plaintext message using multiple private keys intended for a single recipient for decryption. This provides a solution to situations requiring an extra level of security through multiple monitoring and multiple controls. The additional private keys used by the process also improve the complexity of the algorithm which limits the chance of breaking the algorithm using brute force or systematic attack.
