Abstract:
PKI offers authentication via digital certificates, which are signed and provided by Certificate Authority (CA). A certificate can be signed by single CA or multiple CAs. A document signed by multiple CAs has less probability to be forged as compared to signed by a single CA. CA is a single point of failure, if CA issue forged certificate intentionally or maliciously the whole PKI system effected. Still PKI ensures a secure method for exchanging sensitive information over unsecured channels through the use of cryptographic public private key pair, issued by Certification Authority (CA) but eve

Abstract:
With the development of cloud services and the Internet of Things, the integration of heterogeneous systems is becoming increasingly complex. Identity management is important in the coordination of various systems, and public key infrastructure (PKI) is widely known as an identity management methods. In PKI, a certificate authority (CA) acts as a trust point to guarantee the identity of entities such as users, devices, and services. However, traditional CAs that delegate the operations to a specific organization are not always suitable for heterogeneous services, and a new methodology is requi

Abstract In interdomain communication, confirming member identity and ensuring security is critical, yet identity forgery remains a challenge. Traditional solutions rely on a Certification Authority (CA) to issue authentication certificates and create a trust chain for identity verification. However, different security domains often have incompatible signature mechanisms, complicating certificate management and authentication. We propose a novel ring signature algorithm based on SM9 to address these issues. This algorithm enables member authentication across different domains, ensuring securit

Abstract:
Modern Public Key Infrastructures (PKIs) allow users to create and maintain centrally stored cryptographic certificates. These infrastructures use a so-called certificate chain. At the root of the chain, a root Certification Authority (CA) is responsible for issuing the base certificate. Every verification and certification step within the chain is based upon the security of said root CA. Thus, its operation security is of great concern. Since the root certificates are stored locally on the root CA, any Denial of Service (DoS) attack may render the whole certificate chain, which is based on of

Abstract:
Conventionally, public key certificates bind one subject with one static public key so that the subject can facilitate the services of the public key infrastructure (PKI). In PKI, certificates need to be renewed (or revoked) for several practical reasons, including certificate expiration, private key breaches, condition changes, and possible risk reduction. The certificate renewal process is very costly, especially for those environments where online authorities are not available or the connection is not reliable.

Abstract HTTPS is a cornerstone of privacy in the modern Web. The public key infrastructure underlying HTTPS, however, is a frequent target of attacks. In several cases, forged certificates have been issued by compromised Certificate Authorities (CA) and used to spy on users at large scale. While the concept of Certificate Transparency (CT) provides a means for detecting such forgeries, it builds on a distributed system of CT logs whose correctness is still insufficiently protected. By compromising a certificate authority and the corresponding log, a covert adversary can still issue rogue cert

They are self-organized, self-configured and self-controlled infrastructure-less networks. This kind of network has the advantage of being able to be set-up and deployed anywhere and anytime because it has no infrastructure set-up and no central administration.

In this paper we present a new approach for the conventional X.509 Public Key Infrastructures (PKI). Our goal is to reduce the effort to handle signatures in the long term. The novelty is that a Root CA reissues subordinate certificates of final users, but adjusting validity periods to exclude the periods after a revocation. The Root CA also authenticates timestamps. The result is the cleaned PKI, which is simpler than the conventional PKI because: a) there is no revocation; b) there is no intermediary Certification Authority; c) signatures are trustworthy as long as the used cryptographic alg
