Universally Composable Symmetric Encryption
2009 22nd IEEE Computer Security Foundations Symposium, 2009For 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.

Abstract This chapter concerns symmetric encryption and introduces core concepts and algorithms. It explains the difference between stream and block ciphers and demonstrates how their different properties result in different uses. Two important block ciphers are considered in some detail.

Index based symmetric block encryption
2011 2nd National Conference on Emerging Trends and Applications in Computer Science, 2011Based on the principle of symmetric key encryption we present a new method of symmetric block encryption using indices called Index-Based Symmetric Block Encryption. Instead of going through a number of tedious rounds while encrypting the data, the data can be encrypted in just two rounds.

Forward secure searchable symmetric encryption
2017 12th International Conference for Internet Technology and Secured Transactions (ICITST), 2017Data outsourcing to third party clouds poses numerous data security threats. Access by unauthorized users is one of the security threat to the outsourced data. Unauthorized access can be avoided by encrypting the data before outsourcing. However, encrypting data before outsourcing renders it unsearchable to the data owner. Searchable encryption schemes

Attribute-Based Symmetric Searchable Encryption
2020Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly on their outsourced encrypted data while preserving the privacy of both the files and the queries. Unfortunately, majority of the SSE schemes allows users to either decrypt the whole ciphertext or nothing at all.

Symmetric-Key Homomorphic Encryption for Encrypted Data Processing
2009 IEEE International Conference on Communications, 2009The difficulty of processing data in encrypted form has long been the barrier to the widespread use of encryption in data storage applications; improved security or privacy would always imply a sacrifice of functionality. Many applications, such as ASP, requiring a significant amount of processing at the data storage servers are hence precluded from ...
