Section 3 provides preliminary information used in the context of our work. Section 4 describes the proposed zero-watermarking algorithm for medical color images. Section 5 contains an in-depth experimental analysis and comparison. Section 6 concludes this paper and makes suggestions for further ...
A recent technique called digital watermarking is proposed as a complementary approach to cryptography. Digital watermarking is a process in which security or authentication data is imperceptibly embedded within the host data. In this paper, we propose a robust blind image watermarking algorithm for ...
Specified key is not a valid size for this algorithm 问题:System.Security.Cryptography.CryptographicException:“Specified key is not a valid size for this algorithm.” 解决方法:AES加密中参数key应是32位,如果位数不对会报此错。... Error running ‘Application‘: ‘11‘ is not a valid JRE home ...
Side-channel analysis is a non-invasive implementation attack, focusing on extracting leaked information during the algorithm’s execution. Examples of these leakages include the following: timing [1], power consumption [2], electromagnetic emanation [3], sound [4],or cache-timings [5]. In the...
However, the existing subject-sensitive hashing for HRRS images focuses on the overall performance of the algorithm, while the subject-sensitive hashing used in the blockchain should be more sensitive to tampering than in the conventional environment, because the data on the blockchain are difficult...

Therefore, this article shows an overview of topologies of neural networks for use in cryptography. From the most known as is a Tree Parity Machine, through a Permutation Parity Machine to the use one of...
Peter, who presented LUC public-key encryption in DDJ over a year ago, extends the algorithm by adding three new cryptosystems: a Lucas-function El Gamal public-key encryption, a Lucas-function El Gamal digital signature, and a Lu...
There are so many methods for security. Cryptography and stegnography are two important branches so this paper represents two techniques cryptography and stegnography. This paper discuss Blowfish algorithm...doi:10.1016/0968-0004(79)90102-6Grat...
algorithm is issued as the industry standard in 2012.In 2016,it was published as national standard.It takes a 512-bit message as input and outputs a 256-bit hash value.This paper summarizes the design,properties,softwar...
