A k-out-of-n oblivious transfer scheme is the interaction between a receiver and a sender where the sender possesses the messages m₁, m₂, … m_n. The receiver needs to access k messages out of the n messages. The scheme is a mechanism in which the receiver ...

NIST has recently selected CRYSTALS-Kyber as a new public key encryption and key establishment algorithm to be standardized. This makes it important to evaluate the resistance of CRYSTALS-Kyber implementations to side-channel attacks. Software ...

The evolution of quantum computers is considered a serious threat to public‐key cryptosystems (e.g. RSA, ECDSA, ECDH, etc.). This is indeed a big concern for security of the Internet and other data communication and storage systems. The reason ...

Quantum computing threatens public‐key cryptosystems. QKD may solve this problem. QKD has only been evaluated for certain situations. This restricts QKD technology use. This letter proposes an SDN–IoT QKD paradigm. The suggested method distributes ...

The evolution of Connected and Autonomous Vehicles (CAVs) promises improvements in our travel experience and the potential to enhance road safety and reduce environmental impact. This will be utilising highly diverse traffic environments that ...

This paper proposes a method for the integration of QKD in 6G‐V2I networks to enable secure data communication. QKD is used in the end‐to‐end path of vehicle‐to‐infrastructure (V2I) networks. Furthermore, an overarching Software‐Defined Network (SDN), ...

A Verifiable Random Function (VRF) is the public key version of a keyed cryptographic hash. Only the holder of the secret key can compute the hash, but anyone with the public key can verify the correctness of the hash. VRFs are useful for preventing ...

Trilemma in blockchain refers to the infamous problem of simultaneously not delivering the three critical aspects of a ledger: security, scalability, and decentralisation. While security and scalability hinder decentralisation, security is ...

The proposed technique solves the infamous trilemma issue of blockchain. InterPlanetary File System (IPFS), a P2P‐based off‐chain storage, is utilised to ensure that the security is not compromised while stabilising scalability and decentralisation. image ...

As past works have shown, information‐theoretically secure implementations transmitters of Y00 quantum noise randomised cypher are possible. An advance to the provably secure Y00 protocol by bridging gaps between experimental results and ...

Recently proposed security evaluations under the collective attacks with known‐plaintext were too abstract to apply to experiments. Therefore, security analyses directly evaluable with the equipped Y00 transmitters under attack are offered. image image

Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access policy for the other party. In IB‐ME, data encryption is performed by not only a ...

RIB‐ME provides the features of data confidentiality, sender authenticity and efficient revocation, where the security can be reduced to static assumptions in the standard model. image image

Digital signature schemes are used for the authentication and verification of signatures. The Courtois–Finiasz–Sendrier (CFS) digital signature is a well‐known code‐based digital signature scheme based on the Niederreiter cryptosystem. However, ...

A new code‐based digital signature based on McEliece cryptosystems is proposed. To the authors knowledge, the proposed scheme is the first code‐based digital signature based on McEliece with the lower processing time required to construct a valid digital ...

One of the most extensively utilized mechanisms for person authentication is a system built using biometric‐based authentication. However, many applications use biometric authentication devices that do not support any device authentication ...

The most commonly used public key cryptographic algorithms are based on the difficulty in solving mathematical problems such as the integer factorization problem (IFP), the discrete logarithm problem (DLP) and the elliptic curve discrete logarithm ...

Quantum computing poses fascinating challenges for current cryptography, threatening the security of many schemes and protocols widely used today. To adapt to this reality, the U.S. National Institute for Standards and Technology (NIST) is ...

In this article, the authors report on the implementation of a post‐quantum group key exchange protocol, which is proven secure in the so‐called Quantum Random Oracle Model. It is based on a two‐party design called Kyber, which is a finalist in the NIST ...

The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives. Due to solid security and desirable ...

SM2 digital signature algorithm (SM2-DSA) is a Chinese public key cryptography standard, which is also ISO/IEC standard. However, seldom publications show the evaluation results for combination analysis of side-channel and lattice ...

The security of most early fully homomorphic encryption schemes was based on the hardness of the Learning with Errors (LWE) problem. These schemes were inefficient in terms of per gate computations and public‐key size. More efficient schemes were ...

Internet integrating sensor network (IISN) has gained much importance and exponential growth has been seen over the last 20 years. It is typically installed in remote and unattended terrains to monitor, process and collect time-critical and sensitive ...

Identity‐based encryption (IBE), introduced by Shamir, eliminates the need for public‐key 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 ...

A simultaneous Diophantine approximation (SDA) algorithm takes instances of the partial approximate common divisor (PACD) problem as input and outputs a solution. While several encryption schemes have been published and their securities depend on ...

The supersingular isogeny Diffie–Hellman key exchange protocol (SIDH) was introduced by Jao and De Feo in 2011. SIDH operates on supersingular elliptic curves defined over Fp2, where p is a large prime number of the form p=4eA3eB−1 and e_A and e_B ...
