Signcryption dengan Menggunakan Algoritma AAβ dan DSA dalam Mengamankan Dokumen Digital

Abstract

The swift development of the current digital era is directly proportional to the emergence of several security issues in digital data transmission, especially in data confidentiality and authentication. The modernisation of this way of communication method must be given more attention to the security system because of its increasing popularity. In this case, users can overcome it by using various encryption method approaches, one of many ways that can be done is signcryption. Signcryption is a scheme that combines encryption and digital signatures. Where the encryption process provides confidentiality while the signature offers authenticity. Signcryption itself is utilized in providing solutions to the security problems mentioned earlier by combining a relatively new public key algorithm called AAβ with DSA, which is the standard in digital signatures, in the hope that this combination of algorithms could provide integrity, confidentiality, and authentication. The final result of this research is that signcryption with AAβ and DSA algorithms has been successfully carried out by producing an execution time of 1.189 seconds on the signcryption process of the smallest file size of 1 KB and resistant to brute force attacks.
