Fall 2010 - Data Encryption Compression Simulator VU Project
  • admin January 2011
    Security is the key concern in the current electronic era. There are multiple techniques used for data
    encryption and decryption like ACK (Acknowledgement), AES(Advanced Encryption Standard), AKA
    (Authentication and Key Agreement ),CBCM(Cipher Block Chaining with Output Feedback Masking),CHAP
    (Challenge Handshake Authentication Protocol), DES(Data Encryption Standard )etc.
    When we use encryption technique it increases the length of data as well cost of sending it. Use compression
    technique to reduce its length and RSA algorithm to encrypt data to secure data. RSA (which stands for
    Rivest, Shamir and Adleman who first publicly described it) involves a public key and a private key concept.
    The public key known to everyone and is used for encrypting messages. Messages encrypted with the public
    key can only be decrypted using the private key. Signature can be added to the message using private key
    Used for authentication. Pubic key will be used to encrypt data

    Following steps are involved:

    - Write message.
    - Check the message length.
    - Convert message into fixed size packets
    - Compress the message.
    - Encrypt the compressed message using RSA algorithm.
    - Add signature to the message.
    - Send the secure message.
     -Message will be extracted and decrypted using compression algo and private key at recipient

    Maths Puzzle consists of simple questions, you have limited (a few seconds only) to answer each question, The more you answer the maths puzzle more it gets difficult.
    This app ( maths puzzle ) is based on Maths questions from just arithmetic operations i.e Addition, Subtraction, Multiplication and Division. The more you play the more you understand. Your calculations need to be best to become top in your scores in maths puzzle.
