Biometrics and Cryptography 2024

The goals of cryptography are confidentiality, integrity and availability.
Information confidentiality is safeguarded by cryptography, which also makes sure
data has not been altered and that the information originated from the intended
source rather than an unauthorized sender [2].
Symmetric key and asymmetric key cryptography are the two forms of cryptog-
raphy. Using the same secret key, the sender and the recipient encrypt and decode
a message in symmetric cryptography [3]. Refer Figure 1. Most widely used AES
belongs to symmetric key cryptography. Owing to its less complex mathematical
procedures, symmetric key cryptography is typically quicker and more effective
than asymmetric encryption. This makes it appropriate for real-time encryption of
massive amounts of data, like that needed to secure network connections and data
storage.
