Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What cryptographic algorithm is used by the NSA and includes the use of elliptical curves for digital signature generation and key exchange?

A	ECC
B	AES
C	IDEA
D	RSA

Explanation:

Detailed explanation-1: -The Elliptic Curve Digital Signature Algorithm (ECDSA) is a Digital Signature Algorithm (DSA) which uses keys derived from elliptic curve cryptography (ECC).

Detailed explanation-2: -Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller and more efficient cryptographic keys.

Detailed explanation-3: -ECDSA (Elliptic Curve Digital Signature Algorithm) is based on DSA, but uses yet another mathematical approach to key generation. ECC is a mathematical equation taken on its own, but ECDSA is the algorithm that is applied to ECC to make it appropriate for security encryption.

Detailed explanation-4: -Elliptic curve cryptography (ECC) is a public key cryptographic algorithm used to perform critical security functions, including encryption, authentication, and digital signatures.
