“…Cryptography is an imaginative transformation of data into an unreadable format such that it can only be interpreted and used by the intended receiver. The art and science of cryptography is the defense against improper access to sensitive or confidential information [17][18][19][20]. In general, therefore, cryptography is all about shielding and safeguarding information from cybercriminals or someone other than the intended recipient.…”

The concept Web of Things (WoT) goes well beyond the emphasis on the Internet as a means of sharing data, instead of introducing all resources and connections involving computers, data, and people to the Web. It, therefore, focuses on a range of problems and opportunities, thus paving the way for several exciting industries applications. In cryptography a range of main characteristics of chaotic systems such as non-linearity, initial condition sensitivity, and mixing properties are available. These characteristics provide an essential connection between cryptography and chaos. GOST block cipher is based on secret key secrecy. However, when the encryption process with the same key is used for plaintext, the same cipher text is created. Message replication can be easily detected by an adversary who is a bad link in every communication. In this paper, propose to use a 5d chaotic system combined with GOST block cipher to create a new secure Web of Things (WoT) cryptography system. The 5D chaotic system was used to generate chaotic random keys used in GOST algorithm to provide proper security with as high hardness randomly enhances the NIST fifteen statistical tests and modifies key schedule as security operations.

“…As for the second column, it includes the random numbers for the three-dimensional box locations, which it contains the record numbers that include the first name in the first column in the database. Table (3)(4)(5)(6)(7)(8)(9) shows the structure of inverted table that derived from the first column of the original database (database of Iraqi voter). We notice that the first column in the table (3)(4)(5)(6)(7)(8)(9) contains all the names of the first column of the database without repetition while the second column includes numbers )038,849,213,237) refer to the locations of 3D box that contain all the names of ‫.…”

The increase in the amount of data in encrypted databases has caused problems in data processing and retrieval time. In traditional query processing methods, there are many difficulties in execute query over an encrypted database because it is time- consuming. In this paper, proposes technique for querying encrypted databases records, allows authorized users to execute queries without decrypting all the records of the encrypted database. In this technique, inverted tables include the numbers of 3D box cover locations that were created to enhance and speed up the retrieval time of query and improve an approach of data embedding according to the random 3D box. The proposed method has been examined on the Iraqi voter encrypted Database. The retrieval time in (second, millisecond) has been computed for the traditional method of query processing and proposed technique that using inverted tables. The retrieval time of query executing of proposed techniques without retrieval of all the records of the encrypted database is 10.870 (seconds, millisecond) where the retrieval time of query executing of conventional method that’s retrieval of all the records of the encrypted database is 40.682 (seconds, millisecond).

“…Data encryption is one of the most critical areas in information and communication technology, which shields data from alteration or manipulation to prevent security breaches. Additionally, as technology has advanced, image encryption has become popular due to concerns about user privacy [1] and the fact that information security should always be considered [2]. The two forms of encryption are block ciphers and stream ciphers; the stream cipher algorithms encrypt the message using a secret key generator mechanism.…”

A secure image could be achieved by encryption, a technique for securing images over different media transmission lines with privacy and keeping them safe for the receiver. This paper proposes an image encryption approach to achieve excellent security by combining a lightweight encryption algorithm with the chaotic Peter De Jong map. The Lilliput algorithm, lightweight encryption, uses the Peter De-Jones map to produce keys. The suggested approach achieved a suitable level of complexity that matched the historical demands for transmission images. Two methods were used to conduct the tests on a standard image collection: an encrypted image and a generated key. Standard metrics find the similarity between the input and output images to achieve an accurate proposal performance. The encrypted image's entropy was assessed and discovered that it matched the original image values exactly. The results were satisfactory regarding obtaining a precise correlation rate between the original and encrypted photos. The decryption and reconstruction of the image were completed quickly and steadily, with a high success rate and excellent outcomes. The proposed approach was evaluated on a dataset of well-known test photos with unique features, including varying degrees of lightness and shade to create the perfect test.
