Title: Writing program in C++ or Java to implement RSA algorithm for key generation and cipher verification. Objective: To study‚ 1. Public key algorithm. 2. RSA algorithm 3. Concept of Public key and Private Key. Theory: Public Key Algorithm: Asymmetric algorithms rely on one key for encryption and a different but related key for decryption. These algorithms have the following important characteristics: • It is computationally

ABC Institute of Research has sensitive information that needs to be protected from its rivals. The Institute has collaborated with XYZ Inc. to research genetics. The information must be kept top secret at any cost. At ABC Institute‚ the researchers are unsure about the type of key (asymmetric or symmetric) to use. Please formulate a possible solution‚ and describe the advantages and disadvantages of any solution employed. The best type of key to use in this situation would be public-key cryptography

In the history of cryptography‚ the Enigma was a portable cipher machine used to encrypt and decrypt secret messages. More precisely‚ Enigma was a family of related electro-mechanical rotor machines comprising a variety of different models. The Enigma was used commercially from the early 1920s on‚ and was also adopted by the military and governmental services of a number of nations most famously by Nazi Germany before and during World War II. The German military model‚ the Wehrmacht Enigma

A Survey on Satellite Network Security Ma Ting G0902682F mati0004@ntu.edu.sg Abstract Security is an important concern in satellite multicast communications. Due to its highly dynamic broadcast nature‚ the multicast systems generally have a large number of terminal members with frequent join-leave characteristic. Therefore‚ the satellite networks face significant security challenges‚ such as eavesdropping and Denial of Service (DoS). What is more‚ satellite systems are resource-constrained

Digital Signatures Requirements Message authentication protects two parties who exchange messages from any third party. However‚ it does not protect the two parties against each other. In situations where there is not complete trust between sender and receiver‚ something more than authentication is needed. The most attractive solution to this problem is the digital signature. The digital signature is analogous to the handwritten signature. It must have the following properties: •

CRYPTOGRAPHY- ENCRYPTION AND DECRYPTION Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally‚ it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality‚ integrity‚ authentication‚ and non-repudiation. Modern cryptography intersects the disciplines of mathematics‚ computer science

Explain the difference between secret and public keys. Encryption can be a useful deterrent in keeping sensitive information out of the hands of those not authorized and for maintaining the security of a network. Some encryption schemes utilize a secret key and a public key. Each person on the protected network has both a public and a secret key. Everyone who wants to be able to send encrypted information to another person on the network uses the public key. The recipient then uses a secret key
