We sign (handwritten) whenever we do any non-trivial transaction, communication ordeal. A signature serves as a proof of a document, and the informed consent of theperson or organization represented by the person to the contents of the document.Now, with advancing technology, societies all over the world are going electronic formore and more routine tasks. Also, products, services and documents no longer haveto physical to be considered of value and significance e.g. music downloads, movierentals on Internet, legal documents and government notices sent by email, etc. Howdo we manage the trust, and protect the vulnerable party in a digital world? This paperexplores such a technology - digital signatures, and will look into its technicalimplementation, supporting infrastructure, designing, service providers and futurepossibilities.<Your Name> <Your Student Number> 20162of9
Digital Signatures - Explanation, Implementation, Services And FutureAny non-trivial exchange of goods, services or an agreement requires (handwritten)signatures on a document on which terms of the deal are written e.g. sales receipt,employee contract, etc. A signature serves as a proof of a document, and the informedconsent of the person or organization represented by that person to the contents of thedocument. This protects the other party if challenged, as this document will prove thatthe particular party (authentication) approved and the signing party cannot deny (non-repudiation) having done so. In other words, a signature is used to bind signatory tothe document(www.tutorialspoint.com, 2016).Now, with advancing technology, societies all over the world are going electronic formore and more routine tasks. Also, products, services and documents no longer haveto physical to be considered of value and significance. How do we manage the trust,and protect the interests of the person who requires authentication and non-repudiation from the other party? This paper explores such a technology - digitalsignatures, and will look into its technical implementation, supporting infrastructure,designing, service providers and future possibilities.How Do Digital Signatures Work?Digital signatures are a technique based on mathematics which serve the samepurpose for digital assets (documents, files, etc) that a handwritten signature on paperserves. Digital signatures are based on cryptography. Cryptography is the science ofsending messages in a secret form, so that only the intended recipient can read it(Mollin, 2001). Now, cryptography is of two types - symmetric and asymmetric. Insymmetric, a single key is generated for a pair of communicating parties and thatsingle key is used to encrypt (make the data unintelligible) as well as decrypt (convertit back into the original message). This option per se suffers from the difficulty ofsecurely transmitting the secret keys themselves. The other alternative is asymmetric,in which a person has two keys - one public (to the malicious user also), and oneprivate (only known to the owner).
