Electronic Banking: Security Issues

computer. There are four examples of current encryption technology presented below: Digital Signature, Secure Electronic Transaction, Pretty Good Privacy, and Kerberos. 1. Digital Signature Digital Signature was first proposed in 1976 by Whitfield Duffie, at Stanford University. A digital signature transforms the message that is signed so that anyone who reads it can know who sent it. The use of digital signatures employs a secret key (private key) used to sign messages and a public key to...

Keeping Research Confidential

This system is generally preferred to keep information confidential because of the difficulty it is to break the encryption of the asymmetric key. This basically takes the advantages of both systems by using the security of asymmetric in the digital signature which protects the relative security, but faster encryption, of symmetric encryption. Asymmetric encryption is necessary for the key exchange because symmetric encryption alone is not entirely secure. Microsoft explains “The problem with secret...
