to show them the harmful effects that surveillance can have. In order to do that, I have to provide some background. First, I need to explain encryption. Encryption is a fundamental part of today’s technology. It allows for secure exchange of data between two or more parties. Every time you buy something online or log in to your Facebook account, encryption keeps your credit card details and password safe. It does this by scrambling the information before sending it. Using a special set of…

Aegis Secure Key 3.0 has military grade full disk AES 256-bit XTS hardware encryption and is FIPS 140-2 Level 3 validated. You unlock the drive by entering your 7-16 digit PIN before you connect it to your device that way hackers cannot use software on your device to capture your password, and it automatically locks when you unplug it. If an incorrect password is typed 20 consecutive times all the data and the encryption key are erased. It is also dust and water resistant as well as a wear…

1.1 Overview Cryptography is the science/practice of “writing in secret” (“crypto”= “secret, “graphy” = “writing”). Cryptographic functions are generally defined as algorithms or protocols, rules that govern how data is processed to turn plaintext (unencrypted data) into cipher text (encrypted data) [1]. Cryptography is a method of storing and transmitting data in a form that only those it is intended for can read and process. It is considered a science of protecting information by…

enhancements in UMTS that overcome GSM design weaknesses? Ans: 1. Encryption algorithms used in GSM were not disclosed, aiming to achieve ‘security through obscurity’. Their shortcomings were discovered by reverse engineering an actual GSM phone. The design of algorithms was kept secret (it was disclosed only on a need-to-know basis, under and non-disclosure agreement, to GSM manufacturers). A secret authentication or encryption algorithm may be vulnerable since it does not benefit from the…

infrastructure is the combination of software, encryption technologies and services that enables enterprises to maintain the security of their business transactions on over the internet. It integrates digital certificates, public key cryptography and certification authorities into a complete enterprise-wide network security architecture. It is also defined as a set of roles, policies and procedures needed to create, revoke digital certificates and manage public-key encryption. It is used to bind…

It is broadly divided into two types: lockscreen ransomware and encryption ransomware (Microsoft Malware Protection Center). The former prevents access to files by using a full-screen message, while the latter encrypts files with a key known only to the attackers (Microsoft Malware Protection Center). In both cases, the…

CFS has been reported in [40]. CFS pushes encryption services into the file system. CFS supports secure storage at the system level through a standard UNIX file system interface to encrypted files. Users associate a cryptographic key with the directories they wish to protect. Files in these directories…

of security via an open sea. The communication channel between the secure environments is unsecure. The security goals can be met from time to time using encryption. There are three main types of classical encryption methods or ciphers: transposition, substitution and product ciphers. One of the well known and most widely used asymmetric encryption methods is RSA algorithm. Another technology for hiding data within the contents is ‘Digital Watermarking’. Traditional watermarks may be applied to…

shows a surface of the entire process involved in achieving this task. The steps would be divided into two phases. The first phase outlines the encryption and data hiding process while the second phase shows the steps involved in un-hiding and decrypting the record. Phase One Encryption and Data Hiding The following are the steps involved in the encryption and data hiding process 1. The patient would be prompted to login. For a new user, he/she would have to register in order to gain access. 2.…
