Quantum Indistinguishability for Public Key Encryption [PDF]
, 2021 In this work we study the quantum security of public key encryption schemes (PKE). Boneh and Zhandry (CRYPTO\u2713) initiated this research area for PKE and symmetric key encryption (SKE), albeit restricted to a classical indistinguishability phase ...

, 2007 A procedure is described for securely initializing cryptographic variables in a large number of network terminals. Each terminal has a cryptographic facility which performs all necessary cryptographic functions. A key distribution center is established, and a public and secret key pair is generated for the key distribution center.

Lattice‐based unidirectional Proxy Re‐Encryption and Proxy Re‐Encryption+ schemes
IET Information Security, 2021 The concept of Proxy Re‐Encryption (PRE) was introduced by Blaze, Bleumer and Strauss at Eurocrypt in 1998. In this concept, a semi‐trusted proxy user acquires a re‐encryption key from the delegator.

Key Recovery: Inert and Public [PDF]
, 2017 We propose a public key infrastructure framework, inspired by modern distributed cryptocurrencies, that allows for tunable key escrow, where the availability of key escrow is only provided under strict conditions and enforced through cryptographic measures.

Leakage-Resilient Certificateless Public Key Encryption
, 2013 In certificateless public key encryption (CL-PKE), the Private Key Generator (PKG) keeps a master secret key to generate a partial private key corresponding to a user's identity.
