Identity-Based Encryption and Beyond
IEEE Security & Privacy Magazine, 2008In June 2008, the US National Institute for Standards and Technology (NIST) held a workshop entitled, "Applications of Pairing Based Cryptography: Identity-Based Encryption and Beyond," in Gaithersburg, Maryland. In a series of 14 talks and two panel discussions, the presenters at this workshop discussed several aspects of identity-based encryption ...

In real applications, public-key encryption typically requires a mechanism such as public key infrastructure (PKI) to authenticate public keys, e.g., to generate a certificate that some entity or person owns the public key. However, the use of PKI and certificates might be very heavy and cumbersome in some applications.

Downgradable Identity-Based Encryption and Applications
2019In Identity-based cryptography, in order to generalize one receiver encryption to multi-receiver encryption, wildcards were introduced: WIBE enables wildcard in receivers’ pattern and Wicked-IBE allows one to generate a key for identities with wildcard.

Identity-Based Encryption in the Internet of Things
2021 29th Signal Processing and Communications Applications Conference (SIU), 2021Internet of Things (IoT) has been developing rapidly with the use of new technologies today. In addition to offering new applications that make our lives easier, it also reveals serious security and privacy problems. Hundreds of sensors around us or the applications we use can share our private data with other objects without our knowledge.

Universally Composable Identity-Based Encryption
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006Identity-based encryption (IBE) is one of the most important primitives in cryptography, and various security notions of IBE (e.g., IND-ID-CCA2, NM-ID-CCA2, IND-sID-CPA etc.) have been introduced. The relations among them have been clarified recently.

Key Dependent Message Security for Revocable Identity-Based Encryption and Identity-Based Encryption
2018In a revocable identity-based encryption (RIBE) system, the private key and update key are generated separately and combined together to obtain the decryption key. Since the update key is distributed in a public channel, for each user, the private key and the decryption key are essential to his information security. Careless key management, e.g.

Identity-Based Group Encryption Revisited
2018In this paper, we focus on identity-based group encryption. We have revisited “Identity-Based Group Encryption (IBGE)” proposed by Xiling et al. Their scheme claims to achieve anonymity of the receiver. We have shown that the zero-knowledge proof they have used leaks much more information, due to which the verifier who is honest but curious will be ...

Identity-Based Online/Offline Encryption
2008We consider a scenario of identity-based encryption (IBE) where the encryption device (such as a smartcard) has low power. To improve the computation efficiency, it is desirable that part of computation can be done prior to knowing the message and the recipient (its identity or public key).

Identity-based encryption based on DHIES
Proceedings of the 5th ACM Symposium on Information, Computer and Communications Security, 2010Most traditional public key cryptosystems are constructed upon algebraically rich structures, which makes their key pairs combinable, i.e., the combination of some private keys and their corresponding public keys could form a new key pair. Exploring such combinable property, this paper proposes a novel Identity-Based Encryption (IBE) scheme based on ...

Attribute Specified Identity-Based Encryption
2013Fine-grained access control of encrypted data without trusted third party is a challenging task. Using the simple attribute-based encryption has the problem of key escrow, since there exists a trusted authority who is able to generate the secret keys of all users.
