HRM 3400 Lecture 14 Notes – Secure Sockets Layer and Electronic Payment Systems
Introduction
• To address the limitations of wireless devices, the industry has undertaken a
standardization effort for their Internet communications.
• The Wireless Application Protocol (WAP) is a standard set of specifications for Internet
applications that run on handheld, wireless devices.
• It effectively serves as a Web browser for such devices.
• Electronic payment systems are a key component of the e-commerce infrastructure.
• Current e-commerce technology relies on user identification and encryption to
safeguard business transactions.
• Actual payments are made in a variety of ways, including electronic cash, electronic
wallets, and smart, credit, charge, and debit cards.
• Web sites that accept multiple payment types convert more visitors to purchasing
customers than merchants who offer only a single payment method.
• Authentication technologies are used by many organizations to confirm the identity of a
user requesting access to information or assets.
• A digital certificate is an attachment to an e-mail message or data embedded in a Web
site that verifies the identity of a sender or Web site.
• A certificate authority (CA) is a trusted third-party organization or company that issues
digital certificates.
• The CA is responsible for guaranteeing that the people or organizations granted these
unique certificates are, in fact, who they claim to be.
• Digital certificates thus create a trust chain throughout the transaction, verifying both
purchaser and supplier identities.
Secure Sockets Layer
• All online shoppers fear the theft of credit card numbers and banking information.
