This paper evaluates the preimage resistance of the Tiger hash function. We will propose a pseudo-preimage attack on its compression function up to 23 steps with a complexity of 2, which can be converted to a preimage attack on 23-step Tiger hash function with a complexity of 2. The memory requirement of these attacks is 2 words. Our pseudo-preimage attack on the Tiger compression function adop...
Tiger is a cryptographic hash function proposed by Anderson and Biham in 1996 and produces a 192-bit hash value. Recently, weaknesses have been shown in round-reduced variants of the Tiger hash function. Collision attacks have been presented for Tiger reduced to 16 and 19 (out of 24) rounds at FSE 2006 and Indocrypt 2006. Furthermore, Mendel and Rijmen presented a 1-bit pseudo-near-collision fo...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
Conservation investment, particularly for charismatic and wide-ranging large mammal species, needs to be evidence-based. Despite the prevalence of this theme within the literature, examples of robust data being generated to guide conservation policy and funding decisions are rare. We present the first published case-study of tiger conservation in Indochina, from a site where an evidence-based a...
there is limited data in the literature on the normal size of the anterior fontanelle. this cross- sectional study was to determine normal values of anterior fontanelle size on the first day of life, using standard methods. anterior fontanelle size was measured in 400 term and healthy neonates delivered at the shariati hospital, tehran, iran. examination included assessment of head circumferenc...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
the present survey is a correlation study designed to determine extent and type of relation between mid-arm circumference and weight in order to offer a scale for assumption of weight. 390 healthy, adults who are resident in tehran and between the ages 18-65 were selected from visitors at three hospital censers at random. input accumulation was carried out by means of a questionnaire and ...
