WebFeb 6, 2024 · Cloud cryptography is a set of techniques used to secure data stored and processed in cloud computing environments. It provides data privacy, data integrity, and data confidentiality by using encryption and secure key management systems. Common methods used in cloud cryptography include: Webbreak the code for someone who intercepts the message. Discuss the use of keys in cryptography as be‐ ing integral to crea ng a more secure cipher, by giving the person using the cipher a choice, it makes it harder to work out the original message for an interceptor.
