Abstract:
Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfying the policy. ABS has many applications, such as anonymous authentication, and attribute-based messaging systems. But many applications may require a user obtaining attributes from different authorities, which calls for multi-authority ABS schemes.Keywords:

AbstractThe signatures in the real world represent and reveal the senders identity. They also bind the signer with the contents of message. Requirement of any signature system is two folded, first it represent a unique mark by creator of the document in a distinguished manner, secondly the recipient as well as third party may verify the ‘genuineness’ of the document. The authentication and verification of signed document in digital medium is far more complex then hand written signatures. Adoption of digital signature system addresses several issues like privacy, confidentiality and integrity of the document apart from authentication and verification of the document. For digital message system, a solution must be found to these problems simultaneously addressing the legal requirement as laid down in IT Act 2000. In this paper, we present the general model of cryptographic system and will show how public key cryptographic system serves the requirement of digital signature in the light of IT Act 2000.

Recently, an interesting primary transmitter authentication scheme was proposed. The main idea of this scheme is to have the primary transmitter embed cryptographic authentication tag at the physical layer. There are a number of features that make this scheme attractive. In this paper, we investigate the effective coverage areas for the primary and secondary receivers before and after applying this scheme. During the process, we reveal a serious limitation of this scheme, which may prohibit its application in practice.

Key management plays a fundamental role in cryptography as the basis for securing cryptographic techniques providing confidentiality, entity authentication, data origin authentication, data integrity, and digital signatures. The goal of a good cryptographic design is to reduce more complex problems to the proper management and safe-keeping of a small number of cryptographic keys, ultimately secured through trust in hardware or software by physical isolation or procedural controls. Reliance on physical and procedural security (e.g., secured rooms with isolated equipment), tamper-resistant hardware, and trust in a large number of individuals is minimized by concentrating trust in a small number of easily monitored, controlled, and trustworthy elements.

ABSTRACT
Digital signatures are a restrained technique is used to validate the secrete document without any tampering. The hand-written signatures and Digital signature are both rely on the fact that it is very hard to find two signatures with the same person. Nowadays People use public-key cryptography to compute digital signatures by connecting something unique with another person's signature. Sometimes this digital signature called an electronic signature used for acknowledging online transactions. These signatures are commonly used for financial transactions, online transactions, software distribution, and in some common cases these signs are used for security purposes. The digital signatures are using different algorithms and procedures for cryptocurrency and other applications. This paper performs security analysis and the understanding of Digital Signature.

Digital signature authentication scheme provides secure communication between two users. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (authentication and non-repudiation) and that the message was not altered in transit (integrity). The focus Synopsis of this paper is to discuss how to protect communications that occur in a transaction so as to guide against fraudsters and in other cases where it is important to detect forgery or tampering.
