Encryption

1. Introduction In line with the tradition of newer technologies being designed to satisfy upcoming needs, Bluetooth was developed to take over the place of cables that connect mobile devices to their peripherals including but not limited to notebook computers, digital cameras, cellular phones, and personal digital assistants (PDAs). Bluetooth can be defined as open standard that permits communication between diverse devices using a standard short-range wireless radio connection. Even though…

writing. According to Dictionary.com, "Cryptography is the science or study of techniques of secret writing and message hiding." In today 's fast paced and tech savvy world, it isn 't strange to have at least a fleeting knowledge of cryptology and encryption specifically but this relatively young science and field of engineering has very deep roots. The generally agreed upon first example of cryptography at work occurred nearly four thousand years ago and is found in the ancient tomb of the…

802.15.4 protocol and also the implementation of ZigBee radios in the IoT devices. The numerous attacks against ZigBee has been identified and can be classed under the following categories namely, • Sniffing Some ZigBee networks do not use proper encryption and attackers can take this advantage to sniff all the communications with the use of proper equipment’s. Sniffing attack in a ZigBee network generally refers to the process of collecting all the available information from a network, which is…

What is a VPN? It stands for virtual private network. Its main purpose is to secure the connections between the host and the server. It fulfills that purpose by using tunneling protocols, encryption, data encapsulation and certified connections to protect the identity of the host. The simplest way to think about it is to compare it to a LAN connection but without wiring. The History of VPN: Early VPNs were often set up to give individual employees secure remote access to their company…

to this ransomware like Cerber, Hakuna Matata, havoc, and many others. All of them encrypt the behavior or more or less the same - the request for the victim's file and fee. The only major difference is the size of the type of ransom and use of encryption technique but the distribution method is same. Why Jhon Woddy Ransomware is dangerous? Once this scareware infiltrated the computer then, it encrypts the file of the victim and adds the file name with ".KilledXXX" extension like "Sample.jpg"…

tunnels with IPsec/TSL/DTSL encryption capabilities provide security in transit. To further increase security, one can encrypt the data before the transmission encryption process. Data in archive and rest is less vulnerable than in use data, if sufficient safeguards are in place. Data at rest resides on storage devices such as hard drives. Drive encryption such as bit locker which encrypts the entire hard drive except for the boot volume can be beneficial. This encryption used in conjunction…

message, so that it cannot be found easily, in cryptography the aim is to hide the meaning of the message through the means of encryption. These all are part of secret writing. Written with the purpose of covering or hiding the message so that no other individual, except the…

Professor Doupé, Thank you for your reply, and for your questions. We are excited to potentially have your guidance in our research, and hope we have provided clear explanations to your questions below: 1. SSL/TLS encryption secures data flowing between client and server. Using SSL during an authentication attempt could provide a secure way for a non malicious server to authenticate with the device, while blocking out sign in attempts from malware. 2. It seems that many drive by downloads…

Protocol. The drawback of PPTP is that it doesn't give encryption and it depends on the PPP (Point-to-Point Protocol) to implement efforts to establish safety. 2. Site-to-Site VPN Site-to-site is much the same thing as PPTP aside from there is no "dedicated" line being used. It permits distinctive sites of the same company, each with its own particular actual network, to connect together to structure a VPN. Unlike PPTP, the routing, encryption and decryption is finished by the routers on…

force behind the dispute between Apple and the FBI. One of Apple’s primary security features on their iPhones is the random, embedded encryption key that is generated at the time of production. This allows users to only have the ability to access their phones with the correct pin and encryption key combination. If the pin is entered more than ten times, the encryption key is erased, and even Apple claims to have no way to recover the data on the locked phone. The FBI wanted Apple to change this…
