Within the field of cryptography, a trapdoor function, also known as a "one-way function", is an algorithmic puzzle that is simple to compute in one direction, but extremely difficult to solve when taking the inverse approach. This unique feature makes trapdoor functions an invaluable design component that is embedded into a broad range of encrypted messages and cryptographic transactions.
