1. ABSTRACT The security of information available to an organization was primarily provided through physical and administrative means. For example, rugged file cabinets with a combination lock were used for storing sensitive documents and personnel screening procedures were employed during the hiring process. With the introduction of the computer, the need for automated tools for protecting files and other information stored on the computer became evident. This is especially the case for a shared system and the need is even more acute for a network. Computer networks were primarily used by university researches for sending e-mail, and by corporate employees for sharing printers. Under these conditions, security was not given much attention. Today, since the world is going global, and trillions of data are transferred daily across networks, security is looming on the horizon as a potentially massive problem. The generic name for the collection of tools designed to protect data and to thwart hackers is Computer Security. In the project titled “Digital Signatures” security is ensured in the Messaging System of an organization. In this application, if an employee wishes to send confidential information to another employee connected through the intranet of their organization, he first signs the message and then sends it to the recipient. He signs the message using Digital Signatures. The person who receives the message validates the sender and if the message is from an authorized employee, he reads the message. The above operation is performed using Digital Signature Algorithm (DSA). This application makes sure that the security services Authentication, Secrecy, Integrity, and Non-repudiation are
