In the field of cybersecurity, specifically in the realm of cryptography, there exists a problem of authentication, implemented for example as digital signatures, that can verify the identity of the receiver. Digital signatures provide a means to ensure that the intended recipient, in this case Bob, is indeed the correct individual and not someone else,
What is the trade-off in terms of efficiency when using the Elgamal digital signature scheme?

The Elgamal digital signature scheme is a widely used cryptographic algorithm that provides a means for verifying the authenticity and integrity of digital messages. Like any cryptographic scheme, it involves certain trade-offs in terms of efficiency. In the case of the Elgamal digital signature scheme, the primary trade-off lies in the computational overhead required for
