    Study Notes

    Overview of Secure Electronic Transaction (SET) Protocol

    • SET is a protocol designed for secure online credit card transactions.
    • It aims to protect sensitive financial data during transmission over the internet.
    • It's a layered protocol, incorporating cryptography and digital signature techniques.
    • It prevents fraudulent activities by encrypting data and authenticating parties involved.
    • SET is largely considered obsolete in favor of newer, more adaptable, and efficient methods.

    Key Components of SET

    • Digital Certificates: Used to verify the identity of parties involved in the transaction (merchant, bank, cardholder).
    • Digital Signatures: Cryptographic methods used to authenticate the origin and integrity of data exchanged.
    • Encryption: Data encryption ensures that sensitive information (credit card numbers, CVV codes) is unreadable by unauthorized parties.
    • Payment Card Industry Data Security Standard (PCI DSS): While not a direct part of SET, PCI DSS is a set of security standards often implemented by businesses that use SET or similar protocols.

    SET Transaction Process

    • Cardholder authentication: Mechanisms to verify the cardholder's identity and authorization.
    • Merchant authentication: Mechanisms to verify the merchant's identity and legitimacy.
    • Secure message transfer: Encrypts and securely transmits messages between the involved parties.
    • Transaction authorization: The process of authorization of the payment from the cardholder's account.
    • Transaction data validation: Verification of data for accuracy and completeness throughout the transaction.

    Advantages of SET

    • Enhanced security: Provides a robust framework to protect financial information during transmission.
    • Fraud prevention: Strong authentication and encryption help reduce fraudulent transactions.
    • Trust and reliability: Creates a secure payment environment that instills trust in online transactions.

    Disadvantages of SET

    • Complexity: Implementing and maintaining a SET-based system can be complex, demanding specialized technical skills.
    • Compatibility Issues: The protocol could encounter compatibility problems with varying systems and browsers.
    • High implementation cost: Setting up a SET infrastructure can be expensive due to required security infrastructure.
    • Adoption challenges: While SET offered a secure framework, its implementation required significant effort that made large-scale adoption difficult.
    • Decline in use: Newer, more efficient, and easily adapted technologies have largely replaced the need for SET.

    Cryptographic Techniques Used in SET

    • Public-key cryptography: Used for key exchange and digital signatures.
    • Symmetric-key cryptography: Employs a single shared key for encryption and decryption, typically used for data encryption.
    • Hash functions: Generate a unique 'fingerprint' of the data to ensure data integrity.
    • Message authentication codes (MACs): Validate both message integrity and authenticity.

    Current Status and Relevance

    • The broad adoption of other online payment systems, including newer technologies and protocols, has largely diminished the use and necessity of the SET protocol.
    • While sophisticated in its design, SET's complexity and infrastructure requirements proved less adaptable to the evolving needs of the e-commerce landscape.
    • Modern secure payment systems have built upon the concept of the core principles of SET without the significant maintenance burden.
