: Ensuring data is accessible only to authorized parties.

While symmetric encryption uses the same key, Public Key Cryptography solves the problem of key distribution by using two keys: a for encryption and a private key for decryption.

A modern approach offering the same level of security as RSA but with significantly smaller key sizes, leading to faster computations and lower power consumption—ideal for mobile and IoT devices. 4. Cryptographic Data Integrity and Authentication
