Security Using Colors and Armstrong Numbers
In real world, data security plays an important role where confidentiality, authentication, integrity, non repudiation are given importance. The universal technique for providing confidentiality of transmitted data is cryptography. This paper provides a technique to encrypt the data using a key involving Armstrong numbers and colors as the password. Three set of keys are used to provide secure data transmission with the colors acting as vital security element thereby providing authentication. In the present world scenario it is difficult to transmit data from one place to another with security. This is because hackers are becoming more powerful now-a-days.
