Privacy-Preserving Collective Learning With Homomorphic Encryption
IEEE Access, 2021 Deep learning models such as long short-term memory (LSTM) are valuable classifiers for time series data like hourly clinical statistics. However, access to health data is challenging due to privacy and legal issues.

Towards Secure and Efficient "white-box" Encryption [PDF]
Journal of Universal Computer Science, 2019 In many applications implemented in mistrusted environments all operations with the secret key during an encryption operation are "obfuscated" in a way that while an attacker has access to all routines of operations, it will nevertheless be ...

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...

Metasurface-based key for computational imaging encryption
Science Advances, 2021 A single metasurface operates as a reusable generator of different keys to encode various secret images in a computational way. Optical metasurfaces can offer high-quality multichannel displays by modulating different degrees of freedom of light ...

On the Optimality of Quantum Encryption Schemes
, 2005 It is well known that n bits of entropy are necessary and sufficient to perfectly encrypt n bits (one-time pad). Even if we allow the encryption to be approximate, the amount of entropy needed doesn't asymptotically change.

Attribute‐based encryption implies identity‐based encryption [PDF]
IET Information Security, 2017 In this study, the author formally proves that designing attribute‐based encryption schemes cannot be easier than designing identity‐based encryption schemes. In more detail, they show how an attribute‐based encryption scheme which admits, at least, and policies can be combined with a ...

Serial encryption using the functions of real variable
Радіоелектронні і комп'ютерні системи, 2021 Context. Using the functions of a real variable in cryptosystems as keys allow increasing their cryptographic strength since it is more difficult to select such keys. Therefore, the development of such systems is relevant. Objective.

Quantum Information and Computation, 2003 Quantum states cannot be cloned. I show how to extend this property to classical messages encoded using quantum states, a task I call ``uncloneable encryption.'' An uncloneable encryption scheme has the property that an eavesdropper Eve not only cannot read the encrypted message, but she cannot copy it down for later decoding.
