Elliptic curve cryptography or shortly ECC has several advantages over traditional public key cryptography algorithms such as RSA, ElGamal, and DSA. In this post, we are going to talk about the advantages of elliptic curve cryptography against traditional public key cryptography algorithms.

Strong Security with Shorter Key Sizes
ECC provides the same level of security as traditional public key cryptography algorithms but with shorter key sizes. This means that ECC can achieve the same level of security as RSA or ElGamal with much shorter key lengths, which results in faster computation times and lower bandwidth requirements. For example, a 256-bit ECC key is considered to provide the same level of security as a 3072-bit RSA key, making ECC more efficient in terms of computational resources and storage.

Faster Encryption and Decryption
ECC operations, such as key generation, encryption, and decryption, are generally faster compared to traditional public key cryptography algorithms. This is because ECC operations involve shorter key lengths and require fewer computational resources, making it well-suited for resource-constrained environments, such as embedded systems and mobile devices, where computation and bandwidth are limited.
Efficient Resource Utilization
ECC requires less memory, bandwidth, and processing power compared to traditional public key cryptography algorithms. This makes ECC particularly advantageous for constrained environments, such as Internet of Things devices and other resource-limited environments, where efficient utilization of resources is critical.
Scalability
ECC is highly scalable, as the security level can be easily adjusted by changing the key size. This allows for flexible and efficient adaptation to varying security requirements, without compromising performance or efficiency. ECC is also suitable for a wide range of applications, from low-resource devices to high-performance systems, making it versatile and adaptable.
Strong Security Posture
ECC is based on the hardness of the elliptic curve discrete logarithm problem, which is believed to be computationally hard and resistant to attacks by both classical and quantum computers. This makes ECC a promising choice for post-quantum cryptography, as it is considered to be more resistant to potential attacks by quantum computers compared to traditional public key cryptography algorithms.
Lower Bandwidth and Storage Requirements
ECC uses shorter key lengths compared to traditional public key cryptography algorithms, resulting in lower bandwidth and storage requirements. This is particularly advantageous for applications with limited bandwidth or storage capacity, such as IOT devices or mobile applications.
Conclusion
In conclusion, ECC offers several advantages over traditional public key cryptography algorithms, including strong security with shorter key sizes, faster encryption and decryption, efficient resource utilization, scalability, strong security posture, and lower bandwidth and storage requirements. These advantages make ECC well-suited for a wide range of applications, particularly in resource-constrained environments, and make it a promising choice for modern cryptography needs
