Asymmetric Cryptography Symmetric Cryptography
Require two keys one for encrypt and other one to decrypt. Require only one key both for encryption and decryption.
Size of cipher text is same or lager than original text. Size of cipher text is same or smaller than original text.
Encryption process is slow. Encryption process is very fast.
Used to transfer small amount of data. Used to transfer large amount of data.
Provides confidentiality, authenticity and non-repudiation. Only provides confidentiality.
Examples: ECC, DSA and RSA Examples:DES and RC4
Resource utilization is high. Resource utilization is low as compared to asymmetric key encryption.
