Unlike the previous two protocols, the RSA scheme is an example of public-key cryptography: anybody can send a message to anybody else using publicly available information, rather like addresses or phone numbers Each person has a public key known to the whole world and a secret key known only to him- or herself When Alice wants to send message x to Bob, she encodes it using his public key He decrypts it using his secret key, to retrieve x Eve is welcome to see as many encrypted messages for Bob as she likes, but she will not be able to decode them, under certain simple assumptions The RSA scheme is based heavily upon number theory Think of messages from Alice to Bob as numbers modulo N ; messages larger than N can be broken into smaller pieces The encryption function will then be a bijection on {0, 1, , N 1}, and the decryption function will be its inverse What values of N are appropriate, and what bijection should be used Property Pick any two primes p and q and let N = pq For any e relatively prime to (p 1)(q 1): 1 The mapping x xe mod N is a bijection on {0, 1, , N 1} 2 Moreover, the inverse mapping is easily realized: let d be the inverse of e modulo (p 1)(q 1) Then for all x {0, , N 1}, (xe )d x mod N The rst property tells us that the mapping x x e mod N is a reasonable way to encode messages x; no information is lost So, if Bob publishes (N, e) as his public key, everyone else can use it to send him encrypted messages The second property then tells us how decryption can be achieved Bob should retain the value d as his secret key, with which he can decode all messages that come to him by simply raising them to the dth power modulo N Example Let N = 55 = 5 11 Choose encryption exponent e = 3, which satis es the condition gcd(e, (p 1)(q 1)) = gcd(3, 40) = 1 The decryption exponent is then d = 3 1 mod 40 = 27 Now for any message x mod 55, the encryption of x is y = x 3 mod 55, and the decryption of y is x = y 27 mod 55 So, for example, if x = 13, then y = 13 3 = 52 mod 55 and 13 = 5227 mod 55 Let s prove the assertion above and then examine the security of the scheme Proof If the mapping x xe mod N is invertible, it must be a bijection; hence statement 2 implies statement 1 To prove statement 2, we start by observing that e is invertible modulo (p 1)(q 1) because it is relatively prime to this number To see that (x e )d x mod N , we examine the exponent: since ed 1 mod (p 1)(q 1), we can write ed in the form 1 + k(p 1)(q 1) for some k Now we need to show that the difference xed x = x1+k(p 1)(q 1) x is always 0 modulo N The second form of the expression is convenient because it can be simpli ed using Fermat s little theorem It is divisible by p (since x p 1 1 mod p) and likewise 39.

Another common way to express a linear function is known as the point-slope form As the name suggests, we can draw the graph of a function if we know the coordinates of any single point on the line, and if we also know the slope of the line Let s call this the PS form

Figure 19 RSA Bob chooses his public and secret keys He starts by picking two large (n-bit) random primes p and q

For Voltage Consider a circuit with an rms ac input voltage of Ein and an rms ac output voltage of Eout, specified in the same units as Ein Then the voltage gain of the circuit, in decibels, is given by this formula:

The form Here is the standard PS form for a linear function Later in this chapter, we ll figure out how this form is derived:

y y0 = m(x x0) where x is the independent variable, y is the dependent variable, m is the slope, and (x0, y0) are the coordinates of a known point on the graph

His secret key is d, the inverse of e modulo (p 1)(q 1), computed using the extended Euclid algorithm Alice wishes to send message x to Bob

Gain (dB) = 20 log(Eout /Ein ) The base-10 logarithm of a value x is written log x Log functions of base 10 and base e (another type of logarithm sometimes used in physics and engineering) can be determined easily using scientific calculators From now on, when we say logarithm, we mean the base-10 logarithm unless otherwise specified

An example Suppose we re told that there s a linear function whose graph contains the point ( 1, 2) We are also told that the slope of the graph is 2 The independent variable is x, and the dependent variable is y Our task is to draw a graph of the function Let s begin by assigning x0 = 1 and y0 = 2 When we plug these numbers into the stan-
