works as a medium of exchange and uses cryptography to secure all transactions and to control the creation of additional units of the currency. An example of such cryptocurrencies is the bitcoin. In this article, we will understand the following: • Basic meaning of blockchain • What it comprises of • How it works • What it is used for • And its benefits. Basic Meaning of Blockchains: Basically, blockchains are a distributed database of records or public ledger of all transactions…

other string. So in order to know if data is modified or not, key generation from the image [54] is performed on the shares of secret before sending data on servers. For understanding key generation, [54] should…

the reason the field of cryptography was developed, from its early stages of moving letters around in words to the present use of computer programming to keep certain data safe. Cryptography is the reason we can securely use many day to day applications, but with all these developments come issues of unwanted government surveillance that threatens the privacy of citizens. These issues may be detrimental to the privacy of the information sent and received but cryptography is here to stay as a…

Holmes/Scarpetta Project- The Valley of Fear What discipline was involved? Digital Forensics (cryptology)- The process of encrypting messages and examining digital media forensically to find, analyze, and present facts and opinions. What was the equipment used? The ciphers represent the pages of previous editions of Whitaker's Almanack. The first number represented the page number in the Almanac. The second number, C2, was the column number on the page in the book. The numbers that…

1.1 Overview Cryptography is the science/practice of “writing in secret” (“crypto”= “secret, “graphy” = “writing”). Cryptographic functions are generally defined as algorithms or protocols, rules that govern how data is processed to turn plaintext (unencrypted data) into cipher text (encrypted data) [1]. Cryptography is a method of storing and transmitting data in a form that only those it is intended for can read and process. It is considered a science of protecting information by…

communicate. Cryptography is the way we can transmit secret messages so that only the person it is meant for can understand it. The art of coding and decoding messages has progressed immensely through time, and has become increasingly difficult to break with the use of technology. Cryptography’s evolution has transformed the computing world into what it is today, and this comes with positive and negative effects. As long as people have secrets and want to transmit them, cryptography will…

point. Basic idea of Cryptography is to convert original message to encrypted message. Converting can either make the encryption process hidden, so that an intruder remain unknow it Or, can use a known technique and use a hidden key. Some terminology such as Plaintext - original message ,Ciphertext - encrypted message ,Cipher - transforming algorithm for plaintext to ciphertext,Key - infomation used in cipher known…

Decoding the Grimm Brothers "Once Upon a Time" is a very common introduction to a fairy tale. Many fairy tales are well known by people throughout the globe. People may know these tales but they do not actually know what they mean. The Grimm Brothers’ fairy tales contain much symbolism and unique stylistic trends which have the ability to drastically change the meaning of each story that the brothers wrote. Some of these symbolic aspects include childhood innocence, justice and vengeance. A…

message of any length) that is asserted to be as one of a kind to that particular information as a unique mark is to the particular person. Proposed where a vast record must be "compacted" in a safe way before being scrambled with a private key under an open key cryptosystem such as PGP. There are a lot of applications and we will take about two of them, first one is digital signature a numerical plan for exhibiting the credibility of an advanced message or records. A substantial computerized…
