Abstract

“Many people already used facilities in the internet, like e-mail. By using an e-mail, we can send the document (such as .docx, .xlsx, and .txt) easily. But, when we send the document, maybe a man changed the document point illegally without sender and receiver knows. Without the good safety facilities, receiver will receive its document mistrustful. To resolve that problem, digital signature is made.
In this design of security system, we use Digital Signature Algorithm (DSA). DSA is a specific algorithm for digital signature. This algorithm is used by sender to generate pairing key and generate digital signature using private key (encryption process / signing process), and the public key is used to verify it (decryption process / verifying process). The result of digital signature encryption is alphabets and numbers communication.
Using this security system, user can verify the file that has been sent by comparing digital signature that already changed from file to message digest.”
