Q3. What are digital signatures? Explain how digital signatures are able to ensure the authentication and Integrity of business transactions

Ans. Digital signatures are a cryptographic technique used to provide authenticity, integrity, and non-repudiation to digital messages or documents. They are the digital equivalent of handwritten signatures, and they play a crucial role in ensuring the security of business transactions conducted over the internet.

How Digital Signatures Work:

Creation of Digital Signature:

When a sender wants to digitally sign a document or message, a mathematical algorithm generates a unique hash value from the content of the document. The hash value is a fixed-size string of characters that is specific to the document’s content and is unique for each document. The sender then encrypts this hash value using their private key to create the digital signature.

Verification of Digital Signature:

To verify the digital signature, the recipient uses the sender’s public key to decrypt the signature, which produces the hash value. The recipient then generates a new hash value from the received document using the same algorithm. If the two hash values match, it means the document’s content is intact and has not been tampered with since the digital signature was created. If the hash values do not match, the document’s integrity is compromised.

How Digital Signatures Ensure Authentication and Integrity of Business Transactions:

Authentication:

Digital signatures provide authentication by linking the signature to the sender’s identity through their private key. Only the sender possessing the private key can create a valid digital signature. This ensures that the sender’s identity is verified, and the recipient can trust that the document or message indeed came from the claimed sender.

Integrity:

Digital signatures ensure the integrity of the document by creating a unique hash value based on the document’s content. Even a slight change in the document will result in a completely different hash value, making it impossible to alter the document without invalidating the digital signature. Thus, any tampering or modification of the document will be detected during the verification process.

Non-Repudiation:

Digital signatures provide non-repudiation, meaning the sender cannot deny having sent the document. Since the digital signature is uniquely linked to the sender’s private key, they cannot deny their involvement in creating the signature. This feature is crucial in legal and business transactions, as it prevents one party from denying their actions or commitments.

Timestamping:

To further enhance the security, digital signatures can be combined with timestamping services. Timestamping adds a time stamp to the document, which proves that the document existed at a specific time. This feature is essential in legal contracts and agreements to establish when the document was signed and to prevent backdating.

In conclusion, digital signatures use cryptographic techniques to ensure the authenticity, integrity, and non-repudiation of business transactions and digital documents. By providing a secure and reliable method of verifying the sender’s identity and detecting any tampering, digital signatures play a vital role in maintaining the security and trustworthiness of online transactions.

Data Confidentiality: Encryption ensures that sensitive information, such as credit card numbers, personal identification details, and financial data, remains confidential during transmission. Only authorized parties with the appropriate decryption key can access and understand the encrypted data.

Secure Data Transmission: E-commerce transactions involve the exchange of critical information between the buyer and the seller. Encryption secures this data during transit over the internet, protecting it from interception by hackers or unauthorized entities.

Preventing Data Breaches: Encryption acts as a safeguard against data breaches and cyber-attacks. Even if an attacker manages to intercept the encrypted data, it remains useless without the decryption key, making it extremely difficult for them to access sensitive information.

Authentication and Integrity: Encryption ensures the integrity of data by detecting any unauthorized modifications or tampering during transmission. Any alteration to the encrypted data will result in a different decryption outcome, alerting both parties to potential security breaches.

Compliance with Regulations: Many countries and industries have stringent data protection regulations and compliance standards. Implementing encryption in e-commerce ensures adherence to these regulations, enhancing customer trust and loyalty.

Trust and Customer Confidence: Encryption fosters trust and confidence among customers. When consumers see the padlock icon or “https://” in the website URL, they know their information is encrypted, and they are more likely to trust the e-commerce platform with their sensitive data.

Protection against Man-in-the-Middle Attacks: Encryption safeguards against man-in-the-middle attacks, where an attacker intercepts and relays communications between two parties, attempting to alter or steal data. Encrypted data remains secure from such attacks, as unauthorized access is virtually impossible without the decryption key.

Compliance with Payment Card Industry Data Security Standard (PCI DSS): E-commerce platforms that process credit card payments are required to comply with PCI DSS, which includes using encryption to protect cardholder data.

In conclusion, encryption in e-commerce serves as a vital security measure to protect sensitive information during online transactions. Its main objectives are to ensure data confidentiality, secure data transmission, prevent data breaches, maintain data integrity, comply with regulations, build trust among customers, and protect against cyber threats. By implementing encryption, e-commerce businesses can enhance security, protect customer data, and foster a safe online shopping environment.

Q4 (a) Differentiate between debit cards and Credit Cards.

Ans. Debit Cards and Credit Cards are two types of payment cards that allow users to make purchases and payments electronically. However, they function differently, and there are significant differences between the two:

Source of Funds:

Debit Card: A debit card is linked to the cardholder’s bank account. When a transaction is made using a debit card, the payment is deducted directly from the cardholder’s bank account, and the available balance decreases accordingly.

Credit Card: A credit card is not linked to the cardholder’s bank account. Instead, it provides a line of credit extended by the card issuer (usually a bank). When a transaction is made using a credit card, the card issuer pays the merchant on behalf of the cardholder, and the cardholder is required to repay the credit card company later, typically on a monthly billing cycle.

Borrowed Money vs. Own Money:

Debit Card: The money spent using a debit card is the cardholder’s own money, and the transaction involves no borrowing or debt.

Credit Card: A credit card allows the cardholder to borrow money from the card issuer up to a predefined credit limit. The cardholder must repay the borrowed amount within the grace period or pay interest on the outstanding balance if the amount is not repaid in full.

Interest and Fees:

Debit Card: Since a debit card uses the cardholder’s own money, there is no interest charged on transactions made using a debit card. However, some banks may charge minimal transaction fees or maintenance fees for using a debit card.

Credit Card: Credit cards may have interest charges if the cardholder does not pay the full outstanding balance within the grace period. Additionally, credit cards may have annual fees, late payment fees, and other charges.

Credit Score Impact:

Debit Card: Using a debit card does not have any impact on the cardholder’s credit score, as there is no credit extended or debt involved.

Credit Card: Responsible use of a credit card can positively impact the cardholder’s credit score, as timely repayment and low credit utilization demonstrate creditworthiness. However, late payments or high credit utilization can negatively affect the credit score.

Overdraft and Credit Limit:

Debit Card: There is no credit limit associated with a debit card. If there are insufficient funds in the linked bank account, the transaction may be declined, or the account may go into overdraft, leading to overdraft fees.

Credit Card: Credit cards have a predefined credit limit, and the cardholder cannot spend beyond that limit. If the cardholder attempts to make a transaction exceeding the credit limit, the transaction will be declined.

In summary, debit cards are linked to the cardholder’s bank account and use their own money, whereas credit cards allow cardholders to borrow money from the card issuer up to a credit limit. Debit cards have no interest charges, do not impact credit scores, and have no credit limits. On the other hand, credit cards involve interest charges, affect credit scores, and have a credit limit.

Q4 (b) What are the various risks involved in electronic payment system.

Ans. Electronic payment systems offer convenience and efficiency, but they also come with various risks that need to be addressed to ensure secure and safe transactions. Some of the main risks involved in electronic payment systems include:

Security Breaches: One of the most significant risks is security breaches, where hackers or cybercriminals gain unauthorized access to sensitive payment information, such as credit card details or login credentials. This can lead to identity theft, fraud, and financial losses for both customers and businesses.

Phishing and Social Engineering: Phishing attacks involve fraudulent emails or websites designed to trick users into revealing their personal information, such as usernames and passwords. Social engineering tactics exploit human vulnerabilities to manipulate individuals into disclosing confidential information.
