Mathematical physics by satya prakash pdf download Mathematical physics deals with the study of mathematical models which describe the physical world. As such, it continues to be relevant to society, especially as science and technology advances at a rapid pace. The content below is an introduction to this topic. It should give you a better idea of whether or not it's worth reading more about...##Introduction to Cryptography (pdf) An Introduction to Cryptography (in Section 1.1) discusses different techniques used by cryptographers, explains how they work and why they are important for modern-day security systems. ##Introduction to RSA encryption RSA stands for Rivest-Shamir-Adleman algorithm, named after its creators Ron Rivest, Adi Shamir and Leonard Adleman. The article below provides a good introduction to RAmDA encryption. An RSA public key consists of the modulus N = pq, where p and q are two large prime numbers, and "e" is an integer relatively prime to (p-1)(q-1), that is, gcd(e,(p-1)(q-1))=1. An RSA private key is the pair (n,d), where n = pq and d is an integer such that de ≡ 1 mod (p-1)(q-1). The RSA algorithm depends on finding two large prime numbers p and q. Given those two prime numbers the algorithm generates the third number e such that e = 1 mod (p – 1)(q – 1). Next a number d is chosen such that de ≡ 1 mod (p – 1)(q – 1). This process can be performed in polynomial time by the Euclidean algorithm. RSA encryption can be performed by a call to a function named RSADP, component D from CRT. It will have the parameters shown below. where e is the public exponent, n is the public modulus, p and q are the private exponents, x is the plaintext to be encrypted and c = m^e (mod n). The decryption function can be rewritten as follows. where x = c^d (mod n) and c = m^d (mod n). The RSA encryption function can be implemented in C++ using an RSA class that holds various components for use with RSA encryption. The private key can then be generated using this class. Once this has been done, RSA encryption can then be performed using either two keys or one key. cfa1e77820
