Automated Proofs for Asymmetric Encryption

Automated Proofs for Asymmetric Encryption: First results in the random oracle model

Chosen-ciphertext security is by now a standard security property for asymmetric encryption. Many generic constructions for building secure cryptosystems from primitives with lower level of security have been proposed. Providing security proofs has also become standard practice. There is, however, a lack of automated verification procedures that analyse such cryptosystems and provide security p...

Flexible Interface for Automated Proofs

The aartifact system [1] is an automated assistant for formal reasoning. It is currently architected using a client-server model. In order to better support in-class use, and enable greater scalability a JavaScript implementation of key functional areas of the sytem is desired. The automated proof landscape has to date concentrated little effort towards creating suitably usable interfaces. Towa...

Lecture 10 Asymmetric Encryption

Recall that in the last lecture we discussed cryptographic security in the symmetric setting. The typical arrangement is that Alice and Bob share a common key that they use for encryption and decryption. This shared secret creates an distinction between the communicating parties (Alice and Bob) and the adversarial eavesdropper (Eve). The goal in this setting is to ensure that without the shared...

Distributed Searchable Asymmetric Encryption

Searchable asymmetric encryption (SAE) can also be called Public Key Encryption with Keyword Search (PEKS), which allows us to search the keyword on the data of having been encrypted. The essence of Asymmetric searchable encryption is that users exchange the data of encryption, one party sends a ciphertext with key encryption, and the other party with another key receives the ciphertext. Encryp...
