“…In our future work, we will explore methods of obtaining more flexible and revocable tracing keys. Additionally, we will consider whether the traceability system can be incorporated into other lattice-based schemes, such as revocable IBE [70][71][72], identity-based proxy re-encryption [73][74][75], and IBE schemes with equality test [76,77].…”

Identity-based encryption (IBE), introduced by Shamir, eliminates the need for publickey infrastructure. The sender can simply encrypt a message by using the recipient's identity (such as email or IP address) without needing to look up the public key. In particular, when ciphertexts of an IBE do not reveal recipient's identity, this scheme is known as an anonymous IBE scheme. Recently, Blazy et al. (ARES '19) analysed the trade-off between public safety and unconditional privacy in anonymous IBE and introduced a new notion that incorporates traceability into anonymous IBE, called anonymous IBE with traceable identities (AIBET). However, their construction is based on the discrete logarithm assumption, which is insecure in the quantum era. In this paper, we first formalize the consistency of tracing key of the AIBET scheme to ensure that a ciphertext cannot be traced with the use of wrong tracing keys. Subsequently, we present a generic formulation concept that can be used to transform structure-specific latticebased anonymous IBE schemes into an AIBET. Finally, we apply this concept to Katsumata and Yamada's compact anonymous IBE scheme (Asiacrypt '16) to obtain the first quantum-resistant AIBET scheme that is adaptively secure under the ring learning with errors assumption without random oracle.

“…According to the striking development of quantum computers, we need PREs which can resist quantum attacks. Since the Shore algorithm [110] solves the number-theoretic problems in polynomial time, Hou et al recently proposed not only quantumresistant but also identity-based PRE over lattice sets [111]. Dutta et al designed another quantum-resistant PRE which is collusion-resistant, non-transitive, and transparent [112].…”

The Internet of Things (IoT) is increasingly becoming widespread in different areas such as healthcare, transportation, and manufacturing. IoT networks comprise many diverse entities, including smart small devices for capturing sensitive information, which may be attainable targets for malicious parties. Thus security and privacy are of utmost importance. To protect the confidentiality of data handled by IoT devices, conventional cryptographic primitives have generally been used in various IoT security solutions. While these primitives provide just an acceptable level of security, they typically neither preserve privacy nor support advanced functionalities. Also, they overly count on trusted third parties because of some limitations by design. This multidisciplinary survey paper connects the dots and explains how some advanced cryptosystems can achieve ambitious goals. We begin by describing a multi-tiered heterogeneous IoT architecture that supports the cloud, edge, fog, and blockchain technologies and assumptions and capabilities for each layer. We then elucidate advanced encryption primitives, namely wildcarded, break-glass, proxy re-encryption, and registration-based encryption schemes, as well as IoT-friendly cryptographic accumulators. Our paper illustrates how they can augment the features mentioned above while simultaneously satisfying the architectural IoT requirements. We provide comparison tables and diverse IoT-based use cases for each advanced cryptosystem as well as a guideline for selecting the best one in different scenarios and depict how they can be integrated.

“…Because images have inherent characteristics, like high redundancy and a significant correlation between adjacent pixels, it's simple to obtain the value of a pixel's neighbors. As a result, images require an effective way for achieving invulnerability [4]. Image encryption methods majorly use three approaches: (1) pixel permutation: the pixels are scrambled by the algorithm [5,6], (2) pixel substitution: the pixel value is modified by the encryption technique, and (3) visual transformation.…”

In this age of the multi-media, images have an important impact on communication. When users upload images over an insecure communication network, total security is a difficult problem to address in order to maintain image confidentiality. Also, encryption is a technique for keeping images secret. This study gives a basic introduction to cryptography, as well as a concise overview regarding the many image encryption algorithms' elemental security criteria. This paper includes an overview of several image encryption approaches as well as a comparison of discrete image encoding techniques, before coming to a conclusion and recommending future research.
