WebMay 25, 2024 · Cryptography is an essential act of hiding information in transit to ensure that only the receiver can view it. IT experts achieve this by encoding information before sending out and decoding it on the receiver's end. Using an algorithm, IT experts can encrypt information using either symmetric or asymmetric encryption. However, like any other … Web2 days ago · For example, the techniques for guarding against side channel attacks also have to be significantly evolved, tested and validated before critical devices can be considered quantum-secure.
