Cloud Computing is now a fast growing segment of the IT Industry due to the economical

DES III challenge- it took 22 hours and 15 minutes to crack the message. AES(advanced encryption standard) It was first published in year 2001and is more mathematically efficient and elegant cryptographic algorithm [4]. Its main strength rests in the option for various key lengths. It allows to choose 128-bit, 192-bit, or 256-bit key.it is exponentially stronger than the 56-bit key.it uses Permutation-Substitution that is, it involves a series of substitution and permutation steps to create the

Symmetric and Asymmetric Encryption Ian Pierre Gomes Santos 1. Introduction When it comes to information and about this concept related to the digital medium, particularly in the use of public computer networks like the Internet, various services relevant to human’s credibility in computing systems are performed. In fact, they are really important in the fundamentals of security information that are defined by the availability, integrity, confidentiality, authentication, non-repudiation, and

The application and development of quantum computing is still in progress and there aren’t any fully developed quantum computers out there right now. In spite of that, there are many advantages of quantum computing based on the theory and calculations provided by the scientists will benefit us in the future. First of all, there is a difference between quantum computer and traditional computer need to be explained. For example, traditional computer uses long strings of “bits”, which is either zero

Data encryption is the key role in current and future technologies. Many public key cryptography algorithms were presented depending on a specific mathematical problem. It is desired to communicate data with high security over insecure network. Due to sensor technology biometrics has lead to rising concerns about the network security, privacy, trust issues and accuracy. Hence, securing biometric template in public network is great challenge. Because once it is compromised or stolen it cannot be revoked

is used to implement cryptographic algorithms. Operations include RSA, SHA-1, and random number generation. With this operations, TMP can have random data, keys and private data with digital signature. RSA asymmetric algorithm is implemented for encryption with digital signatures. Keys should be 2048-bits RSA keys. TPM is enforced to support the RSA algorithm and use it to encrypt and sign data. Key generation is used to create RSA public and private

It was invented in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman and it is one of the most sued encryption systems used today and it easy to understand and implement in my program. There are 4 Main parts in encrypting and decrypting using RSA. Part 1 Generating Public and Private Keys Before any messages are sent server does this calculations independently 1.1) we should pick two prime numbers we will pick p = 3 and q = 11 1.2) we then calculate n which is p * q it equals 3*11=33 1.3) Then

key. Asymmetric uses multiple different protocols, including, SSL/TLS, IPSec, VPNs, S/MIME, and SSH tunnels. The most popular cipher used in asymmetric encryption is RSA (Rivest, Shamir, Adleman) created in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman. It is based on factoring large numbers in their prime value (Wikipedia). RSA is the most secure. It ranges from 512 bits to 8,000 bits, which is about 2,401 digits.
