E-wallet is assigned a private/public key pair. This E-wallet‚ and the public/private key integrated in the E-wallet‚ provides the client the facility to give payment instructions. Each user engaged in a public/private key scheme has two keys related with them. Using an algorithm‚ these two keys can be used to cipher and decipher messages. The algorithm program makes sure that the message enciphered with the public key can only be deciphered or unscrambled with the private key. It is impossible to cipher

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‚ also known as asymmetric cryptography. It is a type of cryptographic algorithm that requires two separate keys. One of those keys is private‚ and kept secret. The other is public and distributed to those who need it. The keys are both needed since

used‚ as well as significantly stronger encryption keys. Encryption advancements have come about through its application by the military‚ and by advances in computing power and mathematics. The SET protocol relies on two different encryption mechanisms‚ as well as an authentication mechanism. SET uses symmetric encryption‚ in the form of the aging Data Encryption Standard (DES)‚ as well as asymmetric‚ or public-key‚ encryption to transmit session keys for DES transactions (IBM‚ 1998).

Bitcoin: A Peer-to-Peer Electronic Cash System Satoshi Nakamoto satoshin@gmx.com www.bitcoin.org Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution‚ but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer
