Which encryption method is favored for securing online transactions?

The preferred encryption methods for securing online transactions particularly involve RSA and ECC due to their strong security features and efficiency.

RSA (Rivest-Shamir-Adleman) is widely used for secure data transmission since it utilizes two keys—a public key for encryption and a private key for decryption. This dual-key system allows for secure key exchange over insecure channels, making it ideal for online transactions where secure communication is paramount.

ECC (Elliptic Curve Cryptography), on the other hand, is gaining popularity due to its ability to provide strong security with smaller key sizes compared to RSA. This results in faster computations and lower resource consumption, which is particularly beneficial in resource-constrained environments, such as mobile devices or embedded systems.

Both RSA and ECC are designed to withstand common cyber threats, which makes them suitable for securing sensitive data during online activities like e-commerce and financial transactions. Their ability to provide a robust security framework alongside efficient processing capabilities underlines their preference in protocols such as SSL/TLS, which are foundational for securing internet communications.

In contrast, DES (Data Encryption Standard) is largely considered outdated due to its relatively short key length (56 bits), which can be susceptible to brute force attacks, making it less favorable for securing modern online
