Data encryption

Key agreement

Data compression

Error detection

It uses a public key infrastructure

It requires a third-party intermediary

Neither sender nor receiver know the key until the end of the protocol

It is based on symmetric key cryptography

Prime factorization

Discrete logarithm problem

Elliptic curve cryptography

Quantum computing

Alice selects a secret random number a, and Bob selects a secret random number b.

Alice sends α^a to Bob, and Bob sends α^b to Alice.

Alice and Bob select α ∈ ⟨α⟩ the primitive.

Alice receives α^b from Bob, and Bob receives α^a from Alice.

They send α^a and α^b to each other.

They select secret random numbers a and b, respectively.

They compute the agreed key (α^b)^a = α^ab.

They use the key k = α^ab in a symmetric key cryptography scheme.
