Analysis of Available Microcontroller Computing Resources for the Application of Some Cryptographic Hash Functions on Different Internet of Things PlatformsIn the last few years, there have been more and more security vulnerabilities in IoT devices. Some authors suggest the use of security algorithms and...
theory of hash function and thoroughly introduced the implementation process and some attacks;furthermore,the extensive applications of hash functions are analyzed.According to the BLS short signatures scheme,a new short proxy signature scheme is proposed in which the hash function has been effectively ...

1.proof of membership/proof of including如何证明、即上复杂度为O(log(n)) n:假设这根树有n个数据块 2.proof of non-membership 方法是遍历、复杂度为O(n) 但是可以对叶节点按哈希值进行排序,用二分法对两个相邻的数据块分别向上取哈希直到root hash并验证,复杂度为O(log(n))这种Tree称为sorted merkle ...
Eurocrypt is a series of open workshops on the theory and application of cryptographic techniques. These meetings have taken place in Europe every year since 1982 and are sponsored by the International Association for Cryptologic Research. Eurocrypt'93 was held in the village of Lofthus in Norway ...
If someone steals the key, they can easily gain control of the device. Keys should be stored in a safe container and usually not on the user’s device. Some of the popularly used cryptographic protocols for this purpose are MD5 hash and SHA1. Developers should use the latest encryption ...

Hash functions are used as building blocks in certain cryptographic systems. Because of their complexity, program languages with high accuracy performance have to be used. A Python based software application, created by the authors is presented. The main purpose of the application is to ensure the...
This volume presents the proceedings of Eurocrypt '92, held in Hungary. The papers are organized into the following parts: Secret sharing, Hash functions, Block ciphers, Stream ciphers, Public key I, Factoring, Trapdoor primes and moduli (panel report), Public key II, Pseudo-random permutation ...
