private key to decrypt RSA Encryption * Invented in 1978 by Ron Rivest‚ Adi Shamir and Leonard Adleman * Algorithm for public key encryption RSA Encryption Algorithm * 1. Find P and Q two large prime numbers * 2. Choose E such that: 1<E<PQ * E does not have to be prime‚ but must be odd * (P-1)(Q-1) and E must not have no prime factors in common * 3. Compute D such that (DE-1) is evenly divisible by (P-1)(Q-1) * 4. Encryption function is C = (T^E) mod

secured and each packet is stored distributed in different servers‚ log structure is maintained to keep track of each data block. Reconstruction of the data packet makes use of the log files. 2.2 Identify Based Authentication IBE-Identify based encryption/decryption and Identify based signatures are used for ensuring authentication at all levels‚ client and server handshake each other with Random number generated before transferring data establishing a secure connection. 2.3 Effective and secure

Asymmetric algorithms rely on one key for encryption and a different but related key for decryption. These algorithms have the following important characteristics: • It is computationally infeasible to determine the decryption key given only knowledge of the cryptographic algorithm and the encryption key. In addition‚ some algorithms‚ such as RSA‚ also exhibit the following characteristics: • Either of the two related keys can be used for encryption‚ with the other used for decryption

decode data transmitted wirelessly between handheld price-checking devices‚ cash registers‚ and the store’s computers. TJX was using an outdated (WEP) encryption system‚ which made it easy for hackers to crack. The hackers stole user names and password to setup their own TJX account using handheld equipment and also used the data to crack encryption codes. This allowed them to access TJX system from any computer with internet. The hackers also obtained personal information which could be used for
