Name Maryam Mohammed Alshami ID H00204657 Encryption is the process of encoding messages or information in such a way that only authorized parties can read it Important part of computing to keep our file . prOtection. (AERO). mcgrew@cisco.com. AERO. Authenticated Encryption algorithm. Stateful. and self-synchronizing. Easy to use. Robust against nonce misuse and decryption misuse. Saves bandwidth. No nonce, no sequence number. CSE 5351: Introduction to Cryptography. Reading assignment:. Chapter 2. Chapter 3 (sections 3.1-3.4). You may skip proofs, but are encouraged to read some of them.. 2. Computational Difficulty (One-Way Functions). David Froot. Protecting data By encryption . How do we transmit information and data, especially over the internet, in a way that is secure and unreadable by anyone but the sender and recipient?. Encryption is simply the process of transforming information, such as plain text or numbers, using an algorithm. Only those with the algorithm can decipher the encrypted information, and even a relatively simple encryption technique can be difficult to decode without the key. . Rainbows (a.k.a. Spectrums).

Is Encryption Safe?. Yes, Encryption is safe. The amount of time, energy and cost to crack most modern cryptographic technologies makes the act of attempting to decrypt encrypted code an expensive task that is, virtually speaking, inevitable. Although encryption does have vulnerabilities that rest largely outside of the power of the technology. Meaning if you give someone a USB with the key or tell them it.. Cryptography. Is:. A tremendous tool. The basis for many security mechanisms. Is not:. The solution to all security problems. Reliable unless implemented and used properly. Something you should try to invent yourself.
