Streszczenie:

Proxy signature is a very useful technique which allows the original signer to delegate the signing capability to a proxy signer to perform the signing operation. It finds wide applications especially in the distributed environment where the entities such as the wireless sensors are short of computational power and needed to be convinced to the authenticity of the server. Due to less proxy signature schemes in the post-quantum cryptography aspect, in this article, we investigate the proxy signature in the post-quantum setting so that it can resist against the potential attacks from the quantum

Streszczenie:

Certificateless Public Key Cryptography (CL-PKC) scheme is a new standard that combines Identity (ID)-based cryptography and tradi- tional PKC. It yields better security than the ID-based cryptography scheme without requiring digital certificates. In the CL-PKC scheme, as the Key Generation Center (KGC) generates a public key using a partial secret key, the need for authenticating the public key by a trusted third party is avoided. Due to the lack of authentication, the public key associated with the private key of a user may be replaced by anyone. Therefore, the ciphertext cannot be decrypted

Broadcast proxy reencryption (BPRE), which combines broadcast encryption (BE) and proxy reencryption (PRE), is a technology used for the redistribution of data uploaded on the cloud to multiple users. BPRE reencrypts data encrypted by the distributor and then uploads it to the cloud into a ciphertext that at a later stage targets multiple recipients. As a result of this, flexible data sharing is possible for multiple recipients. However, various inefficiencies and vulnerabilities of the BE, such as the recipient anonymity problem and the key escrow problem, also creep into BPRE. Our aim in thi

In a proxy re-encryption scheme, a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in public key settings. Hierarchical identity-based cryptography is a generalization of identity-based encryption that mirrors an organizational hierarchy, which allows a root private key generator to distribute the workload by delegating private key generation and identity authentication to lower-level private key generators.

It is an efficient way to solve open problems in access control scenarios, for example, how to provide data confidentiality and expressive access control at the same time.

Proxy Re-Encryption (PRE) is a cryptographic primitive that allows a proxy to turn an Alice’s ciphertext into a Bob’s ciphertext on the same plaintext. All of the PRE schemes are public key encryption and semantic security. Deterministic Public Key Encryption (D-PKE) provides an alternative to randomized public key encryption in various scenarios where the latter exhibits inherent drawbacks. In this paper, we construct the first multi-use unidirectional D-PRE scheme from Lattices in the auxiliary-input setting.

Streszczenie:

This paper proposes a new certificateless forward secure proxy signcryption scheme based on DLP. Compared with other similar schemes, the scheme has overcome key escrow problem in the id-based cryptography and saving certificate problem in PKI cryptography. The scheme has some good nature, such as unforgeability, non-repudiation, strong identifiability, at the same time, it has forward security and verification. Even the adversaries grab the proxy key in the present phase, they can't forge valid previous signcryption.

Streszczenie:

With the advancement of quantum computing, the utilization of quantum algorithms such as Shor’s algorithm enables the efficient resolution of problems that are intractable in classical computing paradigms, posing a significant threat to traditional signature schemes. Lattice-based cryptography is considered one of the most promising post-quantum cryptographic algorithms due to its computational advantages and potential resistance to quantum attacks. Proxy signature is an authorization mechanism that allows the original signer to delegate the signing power to a proxy. The security of existing p

It has been said that quantum cryptography in general offers a secure solution to the problem of key enhancement. This means that two parties who already share a small secret key, can use quantum protocols to establish a new large secret key. This large secret key can be arbitrarily long and is unbreakable. Thus, to date, the main contribution of quantum cryptography has been believed to be quantum key enhancement. This paper shows that quantum cryptography can do significantly more. The quantum protocol described here distributes an unbreakable secret key to the two parties by relying on publ

Streszczenie:

In mobile adhoc networks (MANETs) an efficient and secure key management scheme is extremely crucial. Key management schemes for MANETs are mainly based on identity-based public key cryptography (IDPKC) or certificate-based public key cryptography, both of which has their inherit problem. The ID-PKC has the key escrow problem and certificate based cryptography have a high computational costs of certificates deployment. In this paper, we present a distributed key management scheme, in which a combination of certificate less public key cryptography (CL-PKC) and threshold cryptography is employed

In this paper, we deal with magmas the simplest algebras with a single binary operation. The main result of our research is algorithms for generating chain of finite magmas based on the self-similarity principle of its Cayley tables. In this way the cardinality of a magmas domain is twice as large as the previous one for each magma in the chain, and its Cayley table has a block-like structure. As an example, we consider a cyclic semigroup of binary operations generated by a finite magmas operation with a low-cardinality domain, and a modify the Diffie-Hellman-Merkle key exchange protocol for t

Streszczenie:

Secret ciphers fascinate students and are an ideal subject with which to motivate them to study mathematics. Recent articles in the Mathematics Teacher, for example, have described how various types of ciphers can be taught to high school students to enhance their learning of statistics (Feltman 1979), matrices (Camp 1985), functions and their inverses (Reagan 1986), and remainder arithmetic (Meneeley 1981). Ciphering also offers interesting examples of how so-called “pure” mathematics can be applied to real-world problems (Hilton 1984).
