RQ 1 A function for one block of bits in a hash function is referred to as a compression function. RQ 2 The main arithmetic and logical functions in SHA algorithms include AND, OR, NOT, XOR and the circular shift. RQ 3 The requirement in the replacement of a hash function is to remove the existing hash function and the insertion of the desired function. RQ 4 A one-way function is an algorithm or a function that is used to turn a piece of text into a fixed string of digits and is nearly…

A and B and C), he can create a trapdoor in arbitrary order as one search token, that’s mean he can send one of the following combined keywords (A∥B∥C), (A∥C∥B), (B∥A∥C), (B∥C∥A), (C∥A∥B) or (C∥B∥A) as a query to the remote server. Then the server tests the Bloom filter against the trapdoor and retrieves the associated matched document to DU without needing for the posting list intersection protocol. Our scheme consists of six algorithms KeyGenerator, BuildIndex, DocEncrypt, Trap- doorGen,…

2 DESCRIPTION OF THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data…

IV Methodology The AES algorithm has 4 phases that execute the process in sequential manner. The encryption process is achieved by processing plain text and key for initial and 9 rounds, Same decryption is takes place but in reverse manner. A 4x4 state is formed in each round and particular length data is introduced in it for encryption process.The 10, 12, 14 rounds are there for 128, 192,256 bits in length respectively. Initially a key expansion process is used to expand the basic 16 byte key…

built on conforming to social norms. Likewise, there have always been individuals, throughout history, who have ventured outside of those norms, many times to the dismay or even apathy of their respectively societies. E.E. Cummings’ “anyone lived in a pretty how town,” is perfect example of how individualism is viewed in a conformist society, as well as sheds light on the poet’s own views of conformity. Although conforming to social norms is how people understand the world around them, it is so…

Poets use various poetic devices in their pieces to express more meaning than the words do alone. Each poem is different in the way it uses these poetic devices and illustrates an idea. Alfred Lord Tennyson and Edgar Allen Poe are two great poets with very different styles of poetry. Despite using some of the same literary techniques, they each incorporate poetic devices to express meaning in their poems. Both Tennyson’s “Charge of the Light Brigade” and Poe’s “The Raven” use narrative,…

readers to place themselves in the character’s shoes, allowing them to picture themselves in E.E. Cummings’ “anyone lived in a pretty how town.” The ambiguous pronouns allow Cummings’ reader to place themselves in the characters’ shoes, thereby allowing them to realize that they, too, are on the same path of life as anyone and noone. Cummings describes anyone as living “in a pretty how town” (Cummings 1). This seemingly generic town is brought to a more intensified version, with Cummings’…

where everything is constantly moving at rapid speeds. Just simply watching the waves roll in and out at its own pace can be astonishing and a moment to remember. The beach is great to look at. This paper will include information about a beach’s pretty white sand, gorgeous blue oceans, and clear baby blue skies. Walking along the beach , I can see smooth sand beneath my feet. The grainy texture underneath me as I walk toward the big blue ocean. With each step I take, looking…

She approached the monster shyly, "E-ehm... e-excuse me, c-can you tell me where one can get out of the rain and s-some place warm...?" she said. "Huh...? You must be pretty new here, huh? Well Snowdin is pretty small, Grillby's is the social spot right over there, and if ya don't gotta a place to go, the inn lady is pretty leniant, so she'll probably let ya stay the night." The bunny said. The girl nodded in thanks as she ran towards Grillby's.…
