SSL Complete Guide 2021: HTTP to HTTPS - Elliptic Curve Discrete Log Problem

The video tutorial covers the concept of point multiplication on elliptic curves and introduces the elliptic curve discrete log problem, explaining why it is difficult to solve. It discusses the nature of the problem and its implications in cryptography. The tutorial concludes with an overview of how elliptic curve cryptography can be used for key generation, comparing it to the Diffie Hellman algorithm.

What is an example of point multiplication on an elliptic curve?

• Adding two points together

• Multiplying a point by a scalar

• Subtracting one point from another

• Dividing a point by a scalar

What is the elliptic curve discrete logarithm problem?

• Determining the scalar used in point multiplication

• Calculating the inverse of a point on a curve

• Identifying the curve equation from a point

• Finding the sum of two points on a curve

Why is it difficult to determine the scalar in the elliptic curve discrete log problem?

• Due to the lack of computational power

• Because of the nature of the curve

• Due to the infinite number of possible scalars

• Because the curve is not continuous

How does elliptic curve cryptography compare to the Diffie-Hellman algorithm?

• It uses a different type of curve

• It achieves the same effect using elliptic curves

• It requires more computational resources

• It is less secure than Diffie-Hellman

What is a key application of elliptic curve cryptography discussed in the video?

• Digital signatures

• Key generation over insecure channels

• Hashing algorithms

• Data encryption
