Deniable encryption

The two methods steganography and cryptography can be used together. Thus it is recommended to use encryption in conjunction with steganography. 3. Motivation This research motivation came after I have studied a Computer Forensics Investigations course at Unitec Institute of Technology. The lecturer provided some useful resources to read and gain more…

Wason Selection tasks What if there are 4 cards on the table: A, K, 2 and 7. On one side of the card there is a number and on the other a letter. You have to decide which cards to turn in order to determine if the following statement is false: If a card has a vowel on one side, then it has an even number on the other side. This is called the Wason Selection task a famous reasoning puzzle (Dawson, Gilovich, Regan, 2002). The answer to this problem is cards A and 7 instead of the most commonly…

The article “Quantum Computer Comes Closer to Cracking RSA Encryption” written by Amy Nordrum, shows that Cryptography needs to be important, because of the fast developing of new technology. In her article Ms. Nordrum tells about computer scientists from the MIT which found a way to crack the RSA (Rivest, Shamir and Adleman)-Code. On the fact, that RSA Encryption is used in all our devices it is quite frightening to know that the government is maybe already using this kind of technology for…

Password strength Password complexity policies are designed to deter brute force attacks by increasing the number of possible passwords. When password complexity policy is enforced, new passwords must meet the following guidelines: • The password does not contain a dictionary word or the account name of the user or company. • The password is at least eight (8) characters long and can be up to 128 characters long. • The password contains characters from three of the following four categories: o…

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…

Decoding the Grimm Brothers "Once Upon a Time" is a very common introduction to a fairy tale. Many fairy tales are well known by people throughout the globe. People may know these tales but they do not actually know what they mean. The Grimm Brothers’ fairy tales contain much symbolism and unique stylistic trends which have the ability to drastically change the meaning of each story that the brothers wrote. Some of these symbolic aspects include childhood innocence, justice and vengeance. A…

• ENCRYPTION: If the data present in the hand held devices are not encrypted, it could lead to the ePHI data that can be accessible to anyone who comes in contact with the device. • WIFI CONNECTION: Most of the hand help devices using the wifi connection provided…

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…

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.…
