2. Secure Electronic Transaction (SET):

• Overview: SET is a protocol designed to secure electronic payment transactions over the internet, ensuring the confidentiality and integrity of financial information.
• Advantages:
  • Data Encryption: Encrypts sensitive payment information during transmission, preventing unauthorized access.
  • Authentication: Verifies the identity of both the buyer and the seller in online transactions.

3. 3-D Secure Protocol:

• Overview: 3-D Secure is an additional layer of security for online credit and debit card transactions. It is commonly known by brand names such as "Verified by Visa" and "MasterCard SecureCode."
• Advantages:
  • Increased Security: Adds an extra layer of authentication by requiring a password or one-time code during online transactions.
  • Reduced Fraud: Helps reduce the risk of unauthorized transactions and online fraud.

4. Electronic Money:

• Overview: Electronic money, or e-money, refers to digital currency stored on electronic devices, such as prepaid cards or digital wallets.
• Advantages:
  • Convenience: Enables quick and easy electronic transactions without the need for physical currency.
  • Reduced Risk of Theft: Reduces the risk associated with carrying physical cash.

5. Security in GSM and 3G:

• Overview: Security protocols in GSM (Global System for Mobile Communications) and 3G (Third Generation) mobile networks ensure the confidentiality and integrity of voice and data transmissions.
• Advantages:
  • Secure Communication: Implements encryption algorithms to protect voice and data transmissions from eavesdropping.
  • Authentication: Verifies the identity of mobile devices and subscribers, preventing unauthorized access.

6. Benefits of Internet Security Protocols: a. Enhanced Trust: Internet security protocols build trust among users and businesses by providing secure and reliable transactions. b. Reduced Fraud: Protects against various forms of online fraud, ensuring the safety of financial transactions. c. Legal Compliance: Helps organizations comply with legal and regulatory requirements for digital transactions and communications.
