Identity-Based Encryption Gone Wild [PDF]

, 2006
In this paper we introduce the notion of identity based encryption with wildcards, or WIBE for short. This allows the encryption of messages to multiple parties with common fields in their identity strings, for example email groups in a corporate hierarchy.

Complete Robustness in Identity-Based Encryption

, 2014
Complete robustness (CROB) was proposed to guarantee that for a public key encryption scheme, decryption attempts will fail with high probability if the wrong decryption key is used to decrypt a ciphertext, even if the keys are maliciously generated by the adversary.

Identity-Based Format-Preserving Encryption [PDF]

Proceedings of the 2017 ACM SIGSAC Conference on Computer and Communications Security, 2017
We introduce identity-based format-preserving encryption (IB-FPE) as a way to localize and limit the damage to format-preserving encryption (FPE) from key exposure. We give definitions, relations between them, generic attacks and two transforms of FPE schemes to IB-FPE schemes.

Scalable Wildcarded Identity-Based Encryption [PDF]

, 2018
Wildcarded identity-based encryption allows a sender to simultaneously encrypt messages to a group of users matching a certain pattern, defined as a sequence of identifiers and wildcards. We propose a new wildcarded identity-based encryption scheme with generalized key delegation, which reduces the ciphertext size to be constant.

Efficient biometric identity-based encryption

Information Sciences, 2018
Abstract As a special case of public key encryption, identity-based encryption (IBE) takes any public known information as public key for encryption and then decrypts a ciphertext by a well-generated private key from private key generator (PKG). Unlike the traditional IBE using a text-based identity (e-mail, etc.) as public key, in this paper, we aim

A tapestry of identity-based encryption: practical frameworks compared [PDF]

International Journal of Applied Cryptography, 2008
This paper surveys the practical benefits and drawbacks of several identity-based encryption schemes based on bilinear pairings. After providing some background on identity-based cryptography, we classify the known constructions into a handful of general

Identity-based Encryption from the Diffie-Hellman Assumption

Journal of the ACM, 2021
We provide the first constructions of identity-based encryption and hierarchical identity-based encryption based on the hardness of the (Computational) Diffie-Hellman Problem (without use of groups with pairings) or Factoring.
