One of the recent developments in telecommunication industry is the introduction of
communications through Internet. The advantage of this approach is its application in
different and diverse fields like e learning, e commerce, e-mail and so on.
As popularity of electronic mail increases, the problem of privacy and security to
the data transmitted also increases. As there are several techniques that provide security to
the data transmitted, the most power full technique for data security is data
encryption.There are several algorithms for encryption .A new algorithm is going to be
discussed in this article will generate a sequence. The algorithm considers a matrix key and
executes a sequence of steps, which generates the sequence. This sequence is represented by
m*m matrix. The algorithm takes m*m successive plain text letters represent them in matrix
form. This matrix plain text is multiplied with generated matrix key to substitute for m*m
cipher text letters. Thus the cipher text obtained becomes impossible to break with out
knowing the key.
Algorithm, example, security analysis, encryption, and decryption.
The use of Internet to provide communications among different levels of people is becoming
very popular. As more and more people were using internet for communication transfer, the problem
of security is also on the rise. Some one sitting or standing next to receiver can easily see the message.
Any intruder can obstruct the message and may see the message.
