motion graphic piece from semiotic point of view. I decided to analyse a motion graphic piece by Estonian creative agency called TOLM and extract denotative and connotative meanings of its imagery. The video piece is about WhiteCryption encryption solution that they offer for their clients. Encryption is a process where message is crypted (encoded, converted) so, that only parties who authorised the encryption can read or decrypt it. Video link can be found at the end of the essay. My plan is to firstly analyse the overall look of the video, what kind of elements are used any why, also the color choice. And what kind of a feel it should give off to its viewers. Then i will look main animated elements which have simple meaning when glancing it quickly, but also deeper meaning when focusing into it a bit more. Overall visual

For example encrypting data and having strong passwords, which are not as easy to bruteforce as for instance is to bruteforce a PIN code. ’’ Some researchers have proposed attribute based encryption method and access controls in cloud computing environments. However, a huge number of devices as a characteristic of IoT was not considered in the existing schemes. Through context extraction based on detection, data owner performs encryption and decryption. In decryption process, each user can decrypt only desired data. Therefore user can receive data in low overhead environment even though there are a large amount of device exists. In the end, access control using context has shown some benefit, but also needs more study about it. ’’ [13]. The issue of privacy should be tackled alongside, so that the devices do not collect and forward too much information nor do the companies sell it to any third parties. The duration
Permuteeritud parem pool aga vasakule. Uut paremat poolt kombineeritakse nüüd XOR funktsiooni kasutades teise 48bitise alamvõtmega, permuteeritakse ning liidetakse XOR-ga vasaku poolega. Toimub jälle kohtade vahetus ja nii edasi 16X järjest. 48bitine alamvõti genereeritakse 56bit peavõtmest. Dekrüpteerimine toimub samu funktsioone vastupidises järjekorras rakendades. /// ==> PILT: (vasask pool, ülevalt alla): 64-bit plaintext => Encrypt K1 // Decrypt K2 // Encrypt K1 => 64-bit cliphertext &&& (parem pool, ülevalt alla): 64-bit plaintext <= Decrypt K1 // Encrypt K2 // Ddecrpyt K1 <= 64-bit cliphertext 50.

an intelligent analysis broke through, and he admitted that the cryptanalyst was on the right track. On September 3, as an airplane was about to fly copies of the trigonometric notebook to an ally's cryptanalysts, the two haggard colonels cracked Mobasheri's cipher. The roster proved to be as detailed as an official army register in describing the officers, making identification easy. But it was so extensive that it took several days to decrypt it and locate the conspirators. A week later all 400 were arrested. This enormous conspiracy, Iranian security 376 THE CODEBREAKKKS police discovered, had not only obtained detailed information on the strength and disposition of Iran's entire armed forces, but had wormed into vital posts that would have enabled it to assassinate on a moment's notice members of the government from the Shah on down. It was ready either to pull a coup and set up its own Communist puppet government
