Performance Study on Image Encryption Schemes

چکیده
Image applications have been increasing in recent years. Encryption is used to provide the security needed for image applications. In this paper, we classify various image encryption schemes and analyze them with respect to various parameters like tunability, visual degradation, compression friendliness, format compliance, encryption ratio, speed, and cryptographic security.

رمزنگاری تصاویر با استفاده از اتوماتای سلولی برگشت پذیر
In this paper, a new structure for image encryption using recursive cellular automatais presented. The image encryption contains three recursive cellular automata in three steps, individually. At the first step, the image is blocked and the pixels are substituted. In the next step, pixels are scrambledby the second cellular automata and at the last step, the blocks are attachedtogether and the ...
متن کاملBrowse searchable encryption schemes: Classification, methods and recent developments
With the advent of cloud computing, data owners tend to submit their data to cloud servers and allow users to access data when needed. However, outsourcing sensitive data will lead to privacy issues. Encrypting data before outsourcing solves privacy issues, but in this case, we will lose the ability to search the data. Searchable encryption (SE) schemes have been proposed to achieve this featur...
متن کاملImage encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...

The growing amount of information that has arisen from emerging technologies has caused organizations to face challenges in maintaining and managing their information. Expanding hardware, human resources, outsourcing data management, and maintenance an external organization in the form of cloud storage services, are two common approaches to overcome these challenges; The first approach costs of...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...
