Webmonoalphabetic ciphers Types of Monoalphabetic Ciphers 1. Shift Ciphers (covered in Section 2.1) 2 Affine Ciphers (covered in Section 2.2) 3. Substitution Ciphers (covered in Section 2.3) Shift Ciphers If x is a numerical plaintext letter, we encipher x by computing the Enciphering formula for Shift Ciphers )y =(x +k MOD 26, where k is in Z26. WebTweakable Block Cipher Having a tweakable block cipher has many applications: Authenticated encryption Disk/memory encryption Hashing: block counter as tweak for HAIFA-like CF (More::: ) There are have been several proposed constructions, most of which rely on a block cipher, andgenericallyintroduce the tweak (XEX, XPX, XTS, etc.)

The shift distance is chosen by a number called the offset, which can be right (A to B) or left (B to A). Web19. Never use ECB! It is insecure. I recommend an authenticated encryption mode, like EAX or GCM. If you can't use authenticated encryption, use CBC or CTR mode encryption, and then apply a MAC (e.g., AES-CMAC or SHA1-HMAC) to the resulting ciphertext. saffron comes from what plant
