Public key infrastructure

Project: With the increased focus on wireless communications, mobile ad hoc networks (MANETs) are attracting much attention in recent years. MANET is an infrastructure less mobile network formed by a number of self-organized mobile nodes; it is different from traditional networks that require fixed infrastructure. Owing to the absence of infrastructure support, nodes in MANET must be equipped with all aspects of networking functionalities, such as routing and relaying packets, in addition to playing

Blockchain Technology supports a distributed ledger system and maintains a growing list of records that are confirmed by the participating people. In blockchain framework, each transaction is recorded in public ledger and stores the information of the transaction. In Current scenario, all the currency transactions between persons or entities are centralized and controlled by some other organizations (Interoperability team). Transferring money will needs bank and merchants who process the payments

In Public Key Cryptosystem there are two keys used i.e. a public key and a private key. Consider an example of Alice and Bob. I Bob wants to send a message to Alice, Bob uses Alice’s public key to encrypt the message and then send that encrypted message to Alice. Alice uses her private key to decrypt the message. Here how does Bob know the Public Key of Alice? Alice might have distributed its Public key through a secure communication channel. This method is applicable only if there is trust/familiarity

Q1: Public Key Infrastructure (PKI) is a popular encryption and authentication approach used by both small businesses and large enterprises for exchanging information based on, it make securely exchange data over networks such as the Internet and verify the identity of the other party. The foundation of a PKI is the certificate authority (CA), which issues digital certificates that authenticate the identity of organizations and individuals over a public system such as the Internet, and the certificates

8. What is the X.509 standard and how does it relate to PKI? The X.509 formatted public key certificate is one of the most important components of PKI. This certificate is a data file that binds the identity of an entity to a public key. The data file contains a collection of data elements that together allow for unique authentication of the own ingenuity when used in combination with the associated private key. 9. What is the difference between Identification and Verification in regard to

Network Security 4th Block With the upraise of Internet use around the world from businesses, private computers and networks there are bound to be people out there trying to get easy money. Hackers and viruses and just human error all represent a potential threat to your networks and sometimes more personal stuff like credit card numbers and social security numbers. This is where the Network Security industry comes into play; it protects your network from viruses

(EFS), which employs public key encryption privileges (Strengthen

communication had become a major role within the people. Communication is done by a medium with sender and receiver. In internet the way of communication takes place by medium of wired and wireless. There is a rapid growth in both wired and wireless infrastructures. It makes use of the customers for the internet connection in many possible ways .In most of the places wireless internet has been used. Most of the wireless spontaneous network is not secure because it is not a planned network and network boundaries

information / data content stored in the cloud server during auditing process. In the proposed work, the reinforcement of TPA handles multiple audit sessions from an outsourced data files and extend the existed Privacy-Preserving Public Auditing Protocol (P3AP) into an Multi-User Public Auditing Protocol (MUPAP). It performs an efficient Multiple Auditing Tasks (MAT) to typically eliminate the burden of tedious and expensive auditing task and improves outsourced data leakage Cloud computing is more convenient

Operating System Security (OS Security) What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and
