Digital File Signcryption using Benaloh and ElGamal Signature Scheme

The rapid development of technology makes it easier for everyone to send files digitally, so there are also many cases of forgery and duplication of files in the general public, for example is on e-voting process. To prevent this from happening, it can be done by applying a cryptographic system in the data transmission process that occurs, one of which is by doing signcryption. E-voting itself focuses on the aspects of authentication, data integrity, and confidentiality. Therefore, research was carried out on the Benaloh algorithm and the ElGamal Signature Scheme in the signcryption method which is expected to overcome the problems mentioned earlier and also can provide integrity, confidentiality and authentication of data transmission which required in the e-voting process. Benaloh and ElGamal Signature Scheme also using the modular exponential method, which produces better performance compared to the RSA factorization. The final result obtained from this research is the successful signcryption process with the results of the execution time signcryption of files of 6 KB d is 8.694 seconds.
