    question regarding cryptography

    try to device your algorithm in such a manner that the key is generated from the data bits itself. In this way, the key will change itself at every time making its decryption very difficult for an outsider. in the decryption algo, the logic must be exactly opposite to that of encryption...

    alternate power source even in power-off condition

    thanks for the quick reply. I was eagerly waitin for that. I dont want to use any battery for the alternate power source. Capacitor in discharging mode is a good option. I already used capacitor ; but it discharges very quickly as soon as i connect it to 555. I think may be it is getting...

    alternate power source even in power-off condition

    hello sir/mam i am using 555 timer for a circuit. But the problem is that the 555 ic should remain energized for 4-5 minutes even when the main power goes off. Can u suggest any circuit which can work as alternate power source when the main power goes off??? Thanks in advance!
