, 2012 We performed a sanity check of public keys collected on the web and found that the vast majority works as intended. Our main goal was to test the validity of the assumption that different random choices are made each time keys are generated. We found that this is not always the case, resulting in public keys that offer no security.

Public-Key Encryption with Delegated Search [PDF]
, 2011 In public-key setting, Alice encrypts email with public key of Bob, so that only Bob will be able to learn contents of email. Consider scenario when computer of Alice is infected and unbeknown to Alice it also embeds malware into message.

3D CUBE Algorithm for the Key Generation Method: Applying Deep Neural Network Learning-Based
IEEE Access, 2020 Current encryption systems are run with a hybrid mode in which symmetric and asymmetric key methods are mixed. This hybrid mode is devised to employ the fast processing speed of the symmetric key while circumventing the difficulty of providing services ...

Privacy Enhancement Scheme (PES) in a Blockchain-Edge Computing Environment
IEEE Access, 2020 With the public key being the parameter users are mostly addressed by on blockchain network, an intruder can connect transactional patterns to the public key and make a probable revelation of the identity of the user.

Public-Key Steganography [PDF]
, 2004 Informally, a public-key steganography protocol allows two parties, who have never met or exchanged a secret, to send hidden messages over a public channel so that an adversary cannot even detect that these hidden messages are being sent. Unlike previous settings in which provable security has been applied to steganography, public-key steganography is ...

A Complete Public-Key Cryptosystem [PDF]
Groups – Complexity – Cryptology, 2009 We present a cryptosystem which is complete for the class of probabilistic public-key cryptosystems with bounded error. Besides traditional encryption schemes such as RSA and El Gamal, this class contains probabilistic encryption of Goldwasser-Micali as well as Ajtai-Dwork and NTRU cryptosystems.

Generic Construction of Dual-Server Public Key Encryption With Keyword Search on Cloud Computing
IEEE Access, 2020 Chen et al. indicated the inner keyword guessing attack coming from the low entropy of keywords, which eliminates the semantic security of most keyword search schemes.
