Public-key cryptography

are accessible to practically anyone. In order to protect our information, we create passwords that allow us-and us alone-to view our most private data, similar to the way in which one would have a key to a safety deposit box with valuables stored carefully within. However, much like any lock and key in existence, the security provided by such a password is not guaranteed. Those with the right resources and knowledge may have the ability to bypass the aforementioned security measures and obtain…

/*************************** Kerberos authentication protocol that establishes a trusted connection between hosts in the untrusted network. The key function of this protocol is that it allows a single sign-on in a distributed network. It's best features lays in the fact that the password does not get shared over the network between nodes. In addition, it uses KDC - key distribution center which keeps the access maintained.…

The Enigma of the 20th Century “Send the U-Boat to (51° 15' 43", -6° 45' 4"); attack at 15:00.” This could have been a message that was ciphered using a secret code during times of war. Cryptography, the study of securely coding messages, has been around for thousands of years (The Enigma Machine Explained). It started out with pencil-and-paper codes, made of substituting letters for each other in the alphabet. Then, there were more geometric codes, relying on using grids to write out messages…

What defines a code is, a system of words, letters, figures or symbols used to replicate a realistic message, which can convey meaning/clues to people. They are generally used for secrecy. Codes function by exchanging given words, letters, figures or symbols into the realistic language that everyone is familiar with. Rather, simultaneously cracking gibberish codes until it reveals a somewhat revealing message. Innumerable codes have been introduced to the world, yet only a few have stood out,…

User connectivity will be controlled and authenticated through active directory. User devices will require and object to be created in active directory which will be used to authenticate the device using 802.1x. When a user device is connected to the network it will initially communicate on a VLAN will only be allowed to communicate with active directory. Then once the device has been authenticated it will place the device on the appropriate VLAN that it will operate on. Any device that has not…

first symmetric key schemes for keyword search over encrypted data are proposed in [27]. The authors consider a setting in which the sender of file encrypts each word of a file separately. Goh [15] proposed a method for secure index using Bloom filters and introduced the notion of semantic security against adaptive chosen-keyword attacks. Determining whether a file contains a keyword can be done securely in constant time. In the public key setting, Boneh et al.[5] first proposed public key…

(Rouse, n.d.). The three most common categories are often described as something you know, something you have and lastly something you are (Rouse, n.d.). So if Linen Planet server was requiring as second factor of authentication with say such as a key fob, an employee ID card or common access card (CAC), the entire compromise would have been impossible. Even with the Linen Plant use of encryption for connections to these servers would not have done anything to stop this type of compromise. The…

Security and integrity, as well as the privacy of user data, remain an important aspect of any computing-related business. Considering that all businesses have turned to technology in a bid to enhance efficiency, it is common to face security related issues. Cloud robotics which is one of the algorithmic processes is a good example of what can be attained using algorithms. This paper is bent on focusing on practical differences in which algorithms are used in solving problems (phishing) through…

the application signs the application with their key as their identity. Developers are required to sign their applications digitally using their private key and through this signature, trust is developed between Google and developers. All applications must be signed. Signature makes applications more tamper resistant because they are difficult to be broken. Once the application is developed, its .apk file is created and is signed with the private key of the developer. The embedded certs are…

to an extent through the encryption of data and proper access control management. Still even with these security measures in place, dubious attackers can breach the security measures and gain access to the data in the following ways [4]. • Cross-site scripting • Cross-site request forgery • Cookie manipulation • OS and SQL injection • Insecure storage • Hidden field manipulation Due to the vulnerabilities listed above, achieving data security in cloud remains a mammoth task. 1) Network…
