investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Related Key Differential Attacks on 27 Rounds of XTEA and Full-Round GOST
In this paper, we present a related key truncated differential attack on 27 rounds of XTEA which is the best known attack so far. With an expected success rate of 96.9%, we can attack 27 rounds of XTEA using 2 chosen plaintexts and with a complexity of 2 27round XTEA encryptions. We also propose several attacks on GOST. First, we present a distinguishing attack on full-round GOST, which can dis...
متن کاملMeet-in-the-Middle Attacks on Reduced-Round GOST
The block cipher GOST (GOST 28147-89) is a Russian standard for encryption and message authentication that is included in OpenSSL 1.0.0. In this paper, we present meet-in-the-middle attacks on several block ciphers, each consisting of 22 or fewer rounds of GOST. Our 22-round attack on rounds 10–31 requires only 5 known plaintexts and a computational effort equivalent to testing about 2 keys for...
متن کاملFirst Differential Attack on Full 32-Round GOST
GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and thus increasingly popular and used [12,15,13,20]. Until 2010 researchers have written that: “despite considerable cryptanalytic efforts spent in the past 20 years...
متن کاملImproved Cryptanalysis on Reduced-Round GOST and Whirlpool Hash Function
The GOST hash function family has served as the new Russian national hash standard (GOST R 34.11-2012) since January 1, 2013, and it has two members, i.e., GOST256 and GOST-512 which correspond to two different output lengths. Most of the previous analyses of GOST emphasize on the compression function rather than the hash function. In this paper, we focus on security properties of GOST under th...
