Two stage password check(one of them being device specific) is used for decoding the message. To avoid data being modified while transmission, different types of feedback function for 100 characters(3-bit sequence specific and different for adjacent row and column input devices in the register shown in figure 4 arranged in a 10 * 10 matrix) having different bit sequence is devised. If a data is lost or extra bit gets added while transmission, the system will automatically show error as all the processes are synchronised. Index Terms - octal word time generation, linear feedback shift register, feedback function, data security, priority encoder, email server, SMTP(simple mail transfer protocol) ,POP(post office protocol), device sensitive password check.Īn efficient method to modify the plain text into an encoded cipher text, not easily predictable ensuring that the key value is irrecoverable when data is attacked while being transmitted. It can provide about 80-85% data security as decoding of data involves inverting the feedback function or generating the binary sequence which will help in retrievi ng the data after some recombination operation. Subhra Mazumdar, Tannishtha Som Abstract - A data encryption technology which ensures secrecy of the data while being transferred over a long distance.
