What are the advantages and disadvantages of public key cryptography http://www.allinterview.com/showanswers/15398.html The primary advantage of public-key cryptography is increased security and convenience: private keys never need to transmitted or revealed to anyone. In a secret-key system, by contrast, the secret keys must be transmitted (either manually or How to find someone else?s public key ? http://www.allinterview.com/showanswers/15411.html Public will be embedded in the Certificate. Hence, if you have a Certificate then we can get the corrosponding public key from it. Pipe A can fill in 20 minutes and Pipe B in 30 mins and Pipe C can e http://www.allinterview.com/showanswers/60433.html a fill - 1/20 per minute b fill - 1/30 per minute c can empty - 1/40 per minute Suppose this take x minute 1 x +1x - 1x --- -- ---- =1 20 30 40 Solve this x=17(approximately) What is a digital signature? http://www.allinterview.com/showanswers/8926.html A digital signature consists of text that is encrypted using the private key of a public key[md]private key pair. The public key is used to decrypt the signature to verify its authenticity. Can we do the project in ENCRYPTION AND DECRYPTION as a operating sy http://www.allinterview.com/showanswers/16950.html Yes we can. All the information will be stored in encrypted form in memory. During fetching, it must be first decrypted by operating system and then can be read.

What is tamper-resistant hardware ? http://www.allinterview.com/showanswers/15484.html Ensuring that various cryptographic keys are provided by their intended users, and only for their intended purposes, temper resistent hardware is introduced. An example temper resistent device is your "SMART CARD". You have to phy What is quantum cryptography ? http://www.allinterview.com/showanswers/15481.html The science of cryptography has existed in one form or another for centuries. Cryptography is the art of encoding and decoding messages for transmission between two parties, while keeping the message secret from unwanted viewers.
