Universally Composable Symmetric Encryption [PDF]
2009 22nd IEEE Computer Security Foundations Symposium, 2009 For most basic cryptographic tasks, such as public-key encryption, digital signatures, authentication, key exchange, and many other more sophisticated tasks, ideal functionalities have been formulated in the simulation-based security approach, along with their realizations.

, 2017 In this chapter, we focus on symmetric encryption. We begin by identifying two different types of symmetric encryption algorithm, namely, stream and block ciphers. We discuss the basic idea behind a stream cipher and consider their properties and applications. We then introduce block ciphers.

Computationally Efficient Searchable Symmetric Encryption [PDF]
, 2010 Searchable encryption is a technique that allows a client to store documents on a server in encrypted form. Stored documents can be retrieved selectively while revealing as little information as possible to the server. In the symmetric searchable encryption domain, the storage and the retrieval are performed by the same client.

Symmetric Key Encryption Based on Rotation-Translation Equation
Symmetry, 2020 In this paper, an improved encryption algorithm based on numerical methods and rotation–translation equation is proposed. We develop the new encryption-decryption algorithm by using the concept of symmetric key instead of public key.

Dynamic searchable symmetric encryption
Proceedings of the 2012 ACM conference on Computer and communications security, 2012Searchable symmetric encryption (SSE) allows a client to encrypt its data in such a way that this data can still be searched. The most immediate application of SSE is to cloud storage, where it enables a client to securely outsource its data to an untrusted cloud provider without sacrificing the ability to search over it.SSE has been the focus of ...

Randomized symmetric block encryption
Proceedings of the First International Conference on Security of Internet of Things, 2012Most of the trivial symmetric block encryption algorithms give the same cipher text for a given set of plain text and key. This property can be used for performing linear and differential cryptanalysis. Using the concept of random data generation we designed a new scheme to give different cipher texts for a given set of plain text and key (when ...

Searchable Symmetric Encryption
ACM Computing Surveys, 2017Searchable Symmetric Encryption (SSE) when deployed in the cloud allows one to query encrypted data without the risk of data leakage. Despite the widespread interest, existing surveys do not examine in detail how SSE’s underlying structures are designed and how these result in the many properties of a SSE scheme.

Symmetric encryption for error correction
2017 20th Conference of Open Innovations Association (FRUCT), 2017The article presents applying basis of symmetric encryption (block ciphering) in the area of coding theory, a specially in detecting and correcting errors of various types: bit inversion, insertion and skipping. For the case of bit inversion, it has been formulated the conditions of guaranteed fix for a given number of errors.

Boolean symmetric searchable encryption
Proceedings of the 8th ACM SIGSAC symposium on Information, computer and communications security, 2013In this article we tackle the issue of searchable encryption with a generalized query model. Departing from many previous works that focused on queries consisting of a single keyword, we consider the the case of queries consisting of arbitrary boolean expressions on keywords, that is to say conjunctions and disjunctions of keywords and their complement.

Symmetric encryption and XML encryption patterns
Proceedings of the 16th Conference on Pattern Languages of Programs, 2009Most of the time information handled by organizations has been collected and processed by computers and transmitted across networks to other computers. How can we protect this information from unauthorized access when it is being transmitted? Encryption provides confidentiality by protecting sensitive information from being read by intruders.
