10/29/13 Data encryption is the only thing that will secure data transmission. Powerpoint: Confidentiality: Keeps information secret from all but authorized people Integrity: Can enforce integrity with hashes Authentication: Provides a way to authenticate entities Non-repudiation: Prevents a party from denying a previous statement or action Cryptology in Business • Increasing concern about the security of data. • More sophisticated attacks • Tremendous growth of computer-related

Network Security When it comes to networking and the security of networks, there are several different methods of protecting networks. Of these differing methods, some of them sound similar, but provide differing levels of security. In the following paragraphs, I will try to explain the differences between some of the methods used. • Explain the difference between historical and statistical logging. Logging is a simple way of keeping a record of activity on a network. There are several types

of research is going on, to improve the performance of issues like handoffs, routing etc. Security is another key issue that needs to be considered, which comes into picture once the communication channel is setup. Many security protocols are being proposed for different applications like Wireless Application Protocol, 802.11 etc. most of them are based on the public and private key cryptography. This paper provides an insight on these cryptographic protocols and also looks into the current

main groups of cryptography: symmetric and asymmetric encryption. For this propose it is easy to decide which of those two we will be using because the application will be communicating with a local database and there will be no need to verify the identity to make a connection and the database will not be required to decrypt this data therefore only one key will be required which will be held by the application. We will be going with symmetric which only needs one key and it is much faster in encrypting/decrypting

to make sure encryption rules are applied to their system and data is protected. Below is the symmetric and asymmetric encryption method to be used. 1) Public Key 2) Private Key 3) IPsec Public Key (Asymmetric): This encryption method will give pair of keys Message is encrypted using the public key and can only be decrypted by private key. Example RSA, Advanced Encryption Standard (AES) * RSA – It is a public key encryption method * It is a standard encryption method especially

Step 6: Add user s to the existing set of users Step 7: The private key for user is computed as: B.3 Leaving Leaving algorithm is invoked when a user wants to leave from the system. The public parameter is generated in the setup phase using all the user’s attribute values. When a user leaves, first step is to update the public parameter PK. In order to keep the public parameter up to date, the version number of the public parameter is updated. After these operations, the particular leaved

Encryption is a very important aspect of our daily lives. Everywhere we go and everything we do now involves some sort of encryption technology. From turning on our cars to using a card access to gain entry to our workplace, encryption is there. More specifically, encryption in communication is a vital component to everyday life. Without encryption, our lives would be much different and unsecure. According to Oded Goldreich (2004), There are 2 main types of encryption: One is called Symmetric-key

Private key: A private key is a tiny bit of code that is paired with a public key to set off algorithms for text encryption and decryption. It is created as part of public key cryptography during asymmetric-key encryption and used to decrypt and transform a message to a readable format. Public and private keys are paired for secure communication, such as email. Explanation for private key A private key is shared only with the key's initiator, ensuring security. For example, A and B represent

Let me clear up a misconception § RSA public/private key encryption is THE leader, in terms of security. For all practical purposes, it is impossible to crack a RSA algorithm. § PGP (Pretty Good Privacy) is probably the best implementation of RSA. It is now owned by Symantec. § Other free products (which do not tightly integrate into email, for example) are available § Understand that PKI is NOT the same thing as public key encryption Fundamentals of Information Systems Security © 2012 Jones
