Popular Algorithms in Asymmetric Cryptography

Several algorithms are used in asymmetric cryptography, each with unique properties and applications:

 

RSA (Rivest–Shamir–Adleman):

  • One of the earliest and most widely used public-key algorithms.
  • Relies on the difficulty of factoring large prime numbers.
  • Commonly used for secure data transmission, such as in HTTPS protocols.

 

Elliptic Curve Cryptography (ECC):

  • Based on the algebraic structure of elliptic curves.
  • Provides equivalent security to RSA with much smaller key sizes, making it efficient for devices with limited computational power.
  • Frequently used in mobile devices, IoT devices, and digital certificates.

 

Diffie-Hellman Key Exchange:

  • Used to securely exchange cryptographic keys over an insecure channel.
  • Relies on the discrete logarithm problem.
  • Although not a direct encryption algorithm, it plays a critical role in establishing secure connections.

DSA (Digital Signature Algorithm):

  • Specifically designed for digital signatures.
  • Provides a method for signing messages and verifying their authenticity.
