The Laws of Cryptography: Public Key Cryptography

The permutation is done so that a third party has a harder time of guessing what the original superincreasing sequence is.

Very roughly speaking, the product of prime numbers is used for encrypting, while the pair of prime factors are used for decrypting.Clearly, this problem can be produced by randomly picking N integers, randomly choosing a subset of them and summing up this subset - which is trivial.

Sending the key via physical mail still could also be intercepted, for it requires exchanging sensitive information to begin with.Cryptography allows us to have privacy, which some consider the 12th human right.
