By encrypting data, it becomes unreadable to unauthorized individuals, protecting it from potential breaches and unauthorized access.

One of the primary ways encryption protects sensitive data is through the use of cryptographic algorithms. These algorithms convert plaintext data into ciphertext, which is a scrambled and unreadable format. The encryption key, which is a unique code, is required to decrypt the ciphertext back into its original form. This ensures that even if an attacker intercepts the encrypted data, they cannot decipher it without the encryption key.

To illustrate the protection offered by encryption, consider the following table:

Data Type	Encryption Method	Example
Personal Details	Symmetric Encryption	Social Security Number (SSN)
Financial Data	Asymmetric Encryption	Credit card number
Communication	Hashing	Passwords
Transaction Data	SSL/TLS	Bank transfer details
Biometric Data	Tokenization	Fingerprint or facial recognition data

As shown in the table, different encryption methods are used to protect various types of data. For example, symmetric encryption is suitable for personal details like the Social Security Number (SSN), as it uses a single key for encryption and decryption. On the other hand, asymmetric encryption is preferred for financial data such as credit card numbers, as it uses a pair of keys – a public key for encryption and a private key for decryption.

Common Encryption Algorithms Used in Mobile Banking

When it comes to encryption in mobile banking, one commonly used algorithm is AES (Advanced Encryption Standard). AES is known for its strong security features and is widely adopted by financial institutions to protect sensitive data.

Another commonly used encryption algorithm in mobile banking is RSA (Rivest-Shamir-Adleman). RSA encryption provides a secure method for data transmission and is often used for key exchange processes.
