When interacting with the SureCheckUSA website, all browser traffic is encrypted. We utilize an ECC algorithm for encryption that help ensure the privacy of website communication sessions while providing a faster response.
Elliptic Curve Cryptography (ECC) and the Rivest–Shamir–Adleman (RSA) algorithm are both widely used public-key cryptosystems, but they differ in several key aspects:
- Key Size:
- ECC uses shorter keys for equivalent security. For example, a 256-bit ECC key provides roughly the same security as a 3072-bit RSA key.
- RSA relies on larger keys due to its reliance on modular exponentiation.
- Computational Efficiency:
- ECC operations (such as key generation, encryption, and decryption) are faster than RSA operations.
- RSA involves more complex modular arithmetic, making it computationally heavier.
- Space Efficiency:
- ECC certificates are smaller, which benefits resource-constrained devices (e.g., IoT devices).
- RSA certificates are larger due to the key size.
- Security Strength:
- Both ECC and RSA provide strong security when implemented correctly.
- ECC’s security is based on the elliptic curve discrete logarithm problem, while RSA relies on the integer factorization problem.
- Vulnerabilities:
- RSA is susceptible to attacks if the key size is insufficient (e.g., when using small keys).
- ECC is generally more resilient against quantum attacks.
- Standardization:
- RSA has been widely used and standardized for a longer time.
- ECC gained popularity due to its efficiency and is now widely adopted.
