advance hardware devices are available like security bridges, routers and switches, these devices can easily save all the data at the time of an incident. On the other hand, there are strong softwares which can provide disaster and incident recovery applications and they can easily retrieve the last working stage of the system by using the advance data storage functionalities and we can retrieve the last working stage of the system by enabling the safe mode property of these tools (Jonathan). This chapter tells the reader that we can make our network communication more secure and reliable by deploying different encryption techniques and that is why Advanced Encryption Standard (AES) for secure communication is used for this purpose. In this technique symmetric key encryption method is used for encrypting the data and traffic as it is being used for high level of encryption and security.…
be assured of success in data or information security. To counter data privacy and security issues, various approaches such as a genetic algorithm or data mining as well as encryption algorithm among others that can be used to effectively prevent and eradicate phishing. Once an algorithm has been settled for, it is essential to understand it which facilitates the implementation which can be in any programming language chosen (Limosani et al., 2016). Encryption algorithms It is essential that…
packets. This will drain the battery of the Zigbee module and can be used to disable the device [9]. The second and most overlooked attack is a physical attack on the actual Zigbee device. Zigbee devices are not very secure. They often store the network key information in plain text without encryption or password protection. Simple AT commands can often be used to retrieve this information if the device is physically accessible. All Zigbee devices in the network have access to the encryption…
Abstract— the focus in this paper is on the symmetric encryption. There are some basic information about this type of cryptography will be reviewed. Then, symmetric cryptography advantages and problems will be covered. After that, comparison on several symmetric algorithms are discussed. These algorithms are DES, Triple DES, AES, RC2, RC4, RC6, and Blowfish. Keywords—Cryptography, Symmetric Encryption, Encryption, Decryption, DES, Triple DES, AES, RC2, RC4, RC6, Blowfish. I. INTRODUCTION…
He also explored that the organizations are really unaware of the process where the data should be encrypted and through which device it is required to be decrypted. There are certain misconception about the encryption that is required to be removed through focusing over the research and the latest findings in the relevant field of interest. Most of the organization believed that the data needs to be decrypted especially in the case when it is being used on mobiles. David was also having the…
R. Buckminster Fuller once said “Humanity is acquiring all the right technology for all the wrong reasons.” ( The words of R. Buckminster Fuller are more relevant now than ever before; especially with the invention and use of dangerous technology such as encryption. Encryption works by using complex mathematical algorithms to scramble the contents of a file or message to another form, called ciphertext, which renders it unreadable to outside parties. Various encryption algorithms, many of which…
Android version greater than 3.0 supports whole disk encryption. Though it is not mandatory and only if the user chooses to encrypt the device he can do so from the device settings. Device Encryption has become mandatory for Android’s latest version 5.0. Various cryptographic algorithms are used for encryption. It also uses hardware based storage for the key using Trusted Execution Environment (TEE) signing capability. It uses 128 bit AES as the encryption algorithm with Cipher Block Chaining…
One such example is the homomorphic encryption which has been embedded into cloud computing, an emerging technology too. Homomorphic encryption allows for data to be in ciphertext form while transmitting it. When retrieving the encrypted data, it is necessary to decrypt it after which it goes back to plain text form. The recent cloud computing technology has been able to incorporate homomorphic encryption but with one disadvantage, it is impossible to search homomorphically encrypted documents…
Recently, a suspect in a Manhattan felony, speaking on a recorded jailhouse call, noted that “Apple and Google came out with these softwares” that the police cannot easily unlock. Apple, Google and other proponents of full-disk encryption have offered several rationales for this new encryption technology. They have portrayed the new policy as a response to the concerns raised by Edward J. Snowden about data collection by the National Security Agency. They say full-disk encryption makes devices…
Diffie-Hellman (DDH) problem: We say that the decisional Diffie-Hellman (DDH) problem is hard if, for any PPT distinguisher A, the function |Pr[A(G_1,q,g,g^a,g^b,g^c )=1]-Pr[A(G_1,q,g,g^a,g^b,g^ab )=1]|, is negligible. 2.2. Outline of the Conjunctive Keyword Searchable Encryption [16] A conjunctive keyword searchable encryption (CKSE) consists of the following four algorithms: KeyGen(1^k): It is run by the senders to initiate the scheme. It takes a security parameter k, and returns a secret…
