To prevent cheating, they want to use their knowledge of cryptography to devise a commitment scheme based on hashing. to start out, they consider possible hash functions. 1) the document contains answers to practice questions for a cryptography exam. it discusses the basic requirements of cryptosystems like security, endpoint security, and secure key management. Rail fence cipher – another kind of transposition cipher in which the words are spelled out as if they were a rail fence. • the system must not be required to be secret, and it must be able to fall into the hands of the enemy without inconvenience. no system is unbreakable!. This tutorial is meant for students of computer science who aspire to learn the basics of cryptography. it will be helpful for networking professionals as well who would like to incorporate various cryptographic algorithms to ensure secure data communication over their networks.
