Explain the weaknesses and security flaws of substitution ciph… The definition of electronic money (also called electronic cash or digital cash) is a term that is still evolving. Browsing the internet is an activity that most of us do every day. Shortly after discovering whole numbers (1, 2, 3, 4, 5…) we realized they fall into two groups: 1. Banks use Hardware Security Module (HSM) … Computers use prime numbers in the encryption techniques. Encryption is used in electronic money schemes to protect conventional transaction data like account numbers and transaction amounts, digital signatures can replace handwritten signatures or a credit-card authorizations, and public-key encryption can provide confidentiality. Encryption is an obscure but critical part of everyday life. The simplest method uses the symmetric or “secret key” system. The differences between asymmetric and symmetric encryption. … Sometimes one may want to verify the origin of a document, the identity of the sender, the time and date a document was sent and/or signed, the identity of a computer or user, and so on. Anonymous schemes are the electronic analog of cash, while identified schemes are the electronic analog of a debit or credit card. Time stamping is very similar to sending a registered letter through the U.S. mail, but provides an additional level of proof. It includes transactions carried out electronically with a net transfer of funds from one party to another, which may be either debit or credit and can be either anonymous or identified. There are various types of email encryption, but some of the most common encryption protocols are: Email encryption services can be used to provide encryption in a few separate but related areas: WhatsApp uses the ‘signal’ protocol for encryption, which uses a combination of asymmetric and symmetric key cryptographic algorithms. Together with the secret key Ki, this random number runs through the A8 algorithm, and generates a session key KC.
