The simple idea of understanding to the DH Algorithm is the following The utility of this model is to help improve investors as some … The algorithm is based on Elliptic Curve Cryptography which is a method of doing public-key cryptography based on the algebra structure of elliptic curves over finite fields. So a person unknown to cryptography can decrypt the message.• We can send cipher text through FAX or E-MAIL.• Lower computational cost since the secret message is recognized only by human eyes and not cryptographically computed. It supports large size keys compared to DES. Cryptography is technique of securing information and communications through use of codes so that only those person for whom the information is intended can understand it and process it. Cryptography Seminar and PPT with pdf report: Cryptography is the practice and the study of concealing the information and it furnishes confidentiality, integrity, and exactness. Transmitting information with access restricted to desired recipient even if transmitted message isintercepted by others. Cryptography is an essential information security tool. Even it play role in important, there also have some negative points. The DH also uses the trapdoor function just like many other ways to do public-key cryptography.
