audio encryption and decryption in matlab

This Algorithm Encrypts Audio file according to user input rate and then perform decryption to access the input information.Encryption is done for security reason for example if you want to transmit some personal audio file into some network and if some hacker hack your network and access that important audio file then he will be not able to perform decryption because data encrypted by sender can only perform decryption so sender may tell the decryption technique to one whom sender want to authorize a ....etc

matlab text encryption and decryption code

Introduction Caeser Cipher

So this is Matlab code for Caesar Cipher Encryption and Decryption.There are many security techniques like Cryptography .The technique which was used in the past days is very simple and easily breakable in its method first a secret key is choosed after choosing key it added to every bit of data for example our data is Data = Attend meeting at noon and Encryption key = 3 so key is of single bit its mean its easily breable in 2.5ms So Now A = C , T = W , E=H , N=Q , D=G , M ....etc

In cryptography the only need of high importance is
security of data.Few ways to achieve it is through public
key cryptography(PKC),secret key cryptography(SKC) and
using hash functions. Generic PKC employs two keys that
are mathematically related although knowledge of one key
does not allow someone to easily determine the other key.
One key is used to encrypt the plaintext and the other key is
used to decrypt the ciphertext(encrypted data). Because a
pair of keys are required, this approach is also called
asymmetric cryptography. T ....etc

RSA

The RSA cryptosystem is a public-key cryptosystem that offers both encryption and digital signatures (authentication). Ronald Rivest, Adi Shamir, and Leonard Adleman developed the RSA system in 1977 .RSA stands for the first letter in each of its inventors' last names.

The RSA algorithm works as follows: take two large primes, p and q, and compute their product n = pq; n is called the modulus. Choose a number, e, less than n and relatively prime to (p-1)(q-1), which means e and (p-1)(q-1) have no common factors except 1. Find another numb ....etc
