Cryptography – types of encryptions and decryptions for sensitive data

[Aeishna R]

Contactless interactions use two types of cryptography – symmetric and asymmetric.

Using the same key for both encryption (locking) and decryption is known as symmetric cryptography (unlock). AES (Advanced Encryption Standard) is superior, more effective, and quantum-resistant in comparison with DES (Data Encryption Standard).

Asymmetric cryptography requires two distinct keys, one for locking and the other for unlocking. We have been utilizing RSA historically. Elliptic curve cryptography (ECC) is three million times more difficult to crack than asymmetric cryptography currently in use.
