In this method the sender uses a key with some enhanced rules and regulations to encrypt the simple text (plain text) into cipher text that need to send to receiver. The receiver also applies the same enhanced rules to decrypt the cipher text in-order to get the Original content of the message. Actually a single key employs for both process, so it is called as symmetric key cryptography. Figure 1.1 Specific Key Cryptography Secret key cryptography contains continuous ciphers (stream

Supplementary Notes Chapter 3 Section 3.2: Polynomial Function of Higher Degree A polynomial function P is given by , where the coefficients are real numbers and the exponents are whole numbers. This polynomial is of nth degree. Far-Left and Far-Right Behavior The behavior of the graph of a polynomial function as x becomes very large or very small is referred to as the end behavior of the graph. The leading term of a polynomial function determines its end behavior. x becomes very large

difference between symmetric and asymmetric key cryptography. Provide an example where each is used. Pg. 282/283. Those that use the same key to encrypt and decrypt are private (symmetric) key ciphers. Those that use different keys to encrypt and decrypt are public (asymmetric) key ciphers. Symmetric key cryptography cannot secure correspondence until after the two parties exchange keys. Asymmetric key cryptography uses a cipher with two separate keys. One is for encryption and one for decryption

OTHER TYPES OF KEYS Gib-head keys are square or flat and tapered with a head. The head should not be left exposed so that there is danger that it will catch on workmen’s clothing, possibly resulting in serious injury. Pin key may either straight or tapered. It is usually a drive fit. Longitudinal assembly at the end of a shaft is easy to do, and in this position, it can transmit heavy power ; size, about one-fourth of the shaft diameter.
