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 to decrypt the information

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

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

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).

It is assumed that the destination knows the public key of the source. A digital signature may be formed by encrypting the entire message with the sender’s private key or by encrypting a hash code
