The correct answer is B. RSA (Rivest Shamir Adleman). For strong, internationally accepted encryption supporting both encryption and decryption of sensitive financial data, RSA is the primary choice as it is a widely used public-key cryptographic algorithm.
Question
PolarFin. a global finance institution, is in the process of migrating to a new transactional system. Given the sensitivity of financial data and international regulations it adheres to. PolarFin needs an encryption algorithm that provides strong security and Is also widely accepted Internationally. The algorithm should also support both encryption and decryption functions. Which cryptographic algorithm should PolarFin consider as its primary choice for this transition?
Options
- AHMAC (Hash-Based Message Authentication Code)
- BRSA (Rivest Shamir Adleman)
- CDES (Data Encryption Standard)
- DBlowfish

Why each option
For strong, internationally accepted encryption supporting both encryption and decryption of sensitive financial data, RSA is the primary choice as it is a widely used public-key cryptographic algorithm.
HMAC (Hash-Based Message Authentication Code) is used for data integrity and authentication to verify that a message has not been altered, but it is not an encryption algorithm for data confidentiality.
RSA (Rivest Shamir Adleman) is a robust and globally recognized public-key cryptographic algorithm suitable for encrypting highly sensitive data. It supports both encryption and digital signatures, meeting the requirements for strong security and international acceptance in financial transactions.
DES (Data Encryption Standard) is an outdated symmetric encryption algorithm that is considered insecure due to its small key size and susceptibility to brute-force attacks, making it unsuitable for modern sensitive financial data.
Blowfish is a symmetric block cipher, and while generally considered strong, it is less widely adopted, standardized, and internationally recognized for broad enterprise use in the financial sector compared to RSA.
