A Study of Demographics, Housing Preferences, Wai Sha Feng Shui Belief and Purchase Intention－An Example from Miaoli County, Tawian
No full textThe residents in Taiwan have experienced two serious earthquakes for the past decades causing house collapse and heavy casualties, which has gradually increased people’s attention on housing safety. In addition to the rapid economic growth bringing about growth in well-being and quality of people’s lives, plus frequently reported builder/contractor fraud cases, purchasing a house is not merely an issue of price; instead, is a demand for home builders/contractors’ brand image and related housing attributes. In view of the fact that many previous researches placed their focuses on people’s intention to purchase real estates in metropolitan areas and a few focuses were placed on less populated counties; this study was then designed with a target population aged 25 to 64 in Miaoli County. The present study investigated the effects of factors of demographic variables, housing preferences, and Wai Sha Feng Shui belief on house purchase intention. This research was conducted using a survey questionnaire, and obtained a total of 235 valid questionnaire copies. The collected data were analyzed with SPSS 18.0 statistics software.
The present study revealed the following findings: (1) House attributes, residency quality, construction safety, and Wai Sha Feng Shui belief had no direct effect on house purchase intention; (2) Area functions had direct effects on house purchase intention; and (3) house purchasing behavior differed in demographic variables. Based on the above findings, some suggestions were proposed to relevant stakeholders for reference.[[abstract]]The residents in Taiwan have experienced two serious earthquakes for the past decades causing house collapse and heavy casualties, which has gradually increased people’s attention on housing safety.

Performance Analysis of Modified SHA-3
No full textAbstractSecurity services have become an inseparable feature of almost all digital transactions. A crucial module of these scheme isintegrity, which is performed using a cryptographic hash function. Secure Hash Algorithm can be an efficient hashing technique.SHA-3 is the most recent and efficient Secure Hash Algorithm. Keccak has been chosen as the official algorithm for SHA-3 in2012. In this paper we propose a modification on the design of Secure Hash Algorithm (SHA-3) on Xilinx Field ProgrammableGate Array (FPGA) device. In order to provide reliable architecture for this algorithm, a concurrent error tolerant scheme forSHA-3 is used. A system based on the combination of SHA-3 and error tolerant scheme is also described. Simulation resultsshows, an efficiency in area and delay of SHA-3 designs

New Disturbance Vector for SHA-0 Collision *
No full textMost of recent collision attacks on SHA-0 are based on the differential path given by Xiaoyun Wang et al. Their disturbance vector was thought to be the best one. We noticed that the way they calculate number of sufficient conditions is not accurate, and we also found some new properties of the third Boolean function MAJ (b ∧ c) ∨ (c ∧ d) ∨ (d ∧ b). In this paper we present a new disturbance vector, and a new differential path is derived from it. In our differential path, there are less sufficient conditions after step 20 but more of them are in the range of message modification techniques, which means this path has great potential in reducing complexity of SHA-0 collision attack. By advanced message modification, all conditions in up to step 23 can be satisfied. The complexity of our attack is 2 35 SHA-0 operations. This is the best single block collision attack on SHA-0
Security and usability of standard has hfunctions, in particular MD-5, SHA-1 and SHA-2
No full textTitle: Security and usability of standard hash functions, in particular MD-5, SHA-1 and SHA-2 Author: Galaczová Barbora Department: Department of Algebra Supervisor: Doc. RNDr. Tůma Jiří, DrSc., Department of Algebra Consultant: Ing. Budiš Petr, Ph.D. Abstract: In the present work we try to digestedly describe standard hash functions, in particular MD-5, SHA-1 and SHA-2. We describe resume of existing attacks on these hash functions. We closely focused on MD-5 collision attacks, because the other hash function collision attacks result from these. Next we describe posibilities of practical usage of hash function collisions, in particular into the qualified certificates area and possible threats. At the end to the present work we describe new hash functions, which could replace current hash functions. This work also contains software to calculate MD-5 hash and search it`s collisions. The software is based on method invented by Czech cryptoanalytist Vlastimil Klíma. Keywords: hash function, collision, qualified certificate, security

Cryptanalysis of Dynamic SHA(2)
No full textIn this paper, we analyze the hash functions Dynamic SHA and Dynamic SHA2, which have been selected as first round candidates in the NIST hash function competition. These hash functions rely heavily on data-dependent rotations, similar to certain block ciphers, e.g., RC5. Our analysis suggests that in the case of hash functions, where the attacker has more control over the rotations, this approach is less favorable than in block ciphers. We present practical, or close to practical, collision attacks on both Dynamic SHA and Dynamic SHA2. Moreover, we present a preimage attack on Dynamic SHA that is faster than exhaustive search. © 2009 Springer-Verlag Berlin Heidelberg.sponsorship: Supported by the Swiss National Science Foundation, project no. 113329.
