Webcryptography becomes a crucial strength of public-key encryption [5]. 3.3 Weaknesses Keys in public-key cryptography, due to their unique nature, are more computationally costly than their counterparts in secret-key cryptography. Asymmetric keys must be many times longer than keys in secret-cryptography in order to boast equivalent security [5]. WebJun 9, 2024 · As the core technology enabling PKI, public key cryptography is an encryption mechanism that relies upon the use of two related keys, a public key and a private key. These two keys are used together to encrypt and decrypt a message. Pairing two cryptographic keys in this manner is also known as asymmetric cryptography. assetsinlinelimit
