In the ever-evolving landscape of cybersecurity, the choice of cryptographic algorithms and certificates plays a pivotal role in ensuring the confidentiality and integrity of sensitive information.
While traditional methods such as the RSA public-key cryptosystem have been the cornerstone of secure communication and data transmission for decades, Elliptic Curve Cryptography (ECC) is emerging as an alternative option for organizations that want to enhance their security posture. With Imperva, you have two options for certificates: Bring your own certificates or have Imperva manage it for you.
Let’s explore why ECC, 2K RSA Certificates, and Imperva-managed certifications are options to consider when building your security environment.
What are RSA Cryptography and SSL Cryptography?
RSA encryption, developed in 1977, is an asymmetric encryption technique that uses two varying but linked encryption keys. Full decryption of an RSA ciphertext is considered infeasible, assuming no efficient algorithm exists for integer factorization.
SSL Cryptography uses public-key cryptography to secure communication between servers and clients, commonly seen in the form of HTTPS in web browsers.
The landscape of SSL has evolved. Organizations now commonly use TLS protocol instead of SSL due to vulnerabilities. Asymmetric encryption, a fundamental aspect of SSL, involves using two keys for encryption and decryption. RSA has been the go-to algorithm for asymmetric encryption, with key sizes of 1024- or 2048-bits. While RSA is proven, ECC is emerging as a more efficient alternative.
Elliptic Curve Cryptography (ECC): Efficiency and Enhanced Security
ECC introduces a shift in cryptographic algorithms. Based on elliptic curves over finite fields, ECC provides the same level of security as RSA but with significantly shorter key lengths. The efficiency of ECC allows for faster computation times, reduced computational power requirements, and decreased bandwidth usage. This makes ECC an ideal choice for resource-constrained devices like IoT devices and mobile phones.
The comparison between ECC and RSA key sizes demonstrates the advantage of ECC in providing the same cryptographic strength with much smaller key sizes (seen in the chart below). ECC’s ability to offer robust security with reduced computational requirements is particularly valuable in today’s diverse and interconnected digital landscape.

2K RSA Certificates: Striking the Right Balance
As websites transitioned from SSL to TLS, certificates became pivotal for establishing secure connections. The industry standard for SSL/TLS certificates is the 2K RSA Certificate, referring to a 2048-bit key size. This key size balances security and performance, ensuring robust encryption without compromising user experience.
