Public key infrastructure

OpenVPN allows authentication using certificates or username/password. OpenVPN can work in two different modes regarding encryption. It can use static encryption or Public Key Infrastructure (PKI). The advantage of static encryption is that it is very easy to configure. The disadvantage of this type setup is that if your encryption key is compromised, all VPN data can easily be decrypted. The PKI mode resolves many of the issues static encryption has. It

Asymmetric cryptographic algorithms, such as RSA, encrypt symmetric keys in key exchange protocols and in hybrid cryptographic systems. Furthermore, entities A and B can now use end-to-end confidentiality and integrity services without the cooperation of any third entity. For example, users can exchange secure e-mail and securely access Web content on an intranet without the immediate cooperation of a mediating server such as CA. Author in [17] introduced a new combined cryptographic method called

DRM Community Cloud (DCC) and consists of the following participants or entities. 3.1. Entities Trusted Service Manager (TSM): Certifying Authority (CA) is responsible for establishing and vouching for the authenticity of public keys. It issues certificates, binds public keys, manages certificate serial numbers, and revokes certificates. In addition to these functions CA also acts as a Trusted Service Manager (TSM) who establishes the link between the RI and MNSP’s worlds from a technical perspective

. PROBLEM STATEMENT & PROPOSED SCHEME This section gives the description about the sensors, respective public and private key pair model and event generation in the network. This is followed by the threat model of the network and the kind of adversaries which pose threat to the network. The design goals of the proposed scheme are also listed. Figure 1. Network model with attack scenario 1 System Model We consider the sensors S={S1,S2, S3, .....Sx} are deployed where x is the population of

The primary explanations behind the Email communication not utilizing encryption is that the current Email encryption results require monotonous operations and hard key administrations. In this way, research about on basic, very secured also effective Email content protection frameworks are in incredible need. This paper will discuss about some background information is provided, state-of-art email encryptions are

combination with a key (number, word, or phrase) to encrypt the plaintext. The same plaintext also encrypts to different cipher text with the use of different keys. The core of modern cryptography is the construction and analyzation of protocols of various aspects in information security such as data integrity and confidentiality, authentication, and non-repudiation. Modern practice of cryptography involves cryptographic method. First cryptographic method is the Symmetric-Key Algorithm also known

Recommendations for Prevention/Mitigation Many ports do not have cyber response plans contained within broader risk plans (Kramek). All of the ports studied by Kramek had a dedicated security officer and a dedicated IT staff, but the security officers’ focus usually remained on traditional physical security threats, and IT was a separate and distinct department from security (Kramek). Kramek states, "cyber security threats were not part of the security officer’s response portfolio". Most security
