industry‚ company and merchant is susceptible and at risk‚ that’s why the steady pace of breaches reinforces the need for an advanced encryption standard (AES) as a last line of defence. In this proposed project‚ we shall be implementing a block level cipher encryption algorithm and technique where vital credit card payment information will be encrypted for a secure payment process and will be decrypted by an authorised administrator. An implementation of an online e-commerce portal where goods/products

this paper are used in protocol composition logic (PCL). Three innovative ideas presented are essential for formal proofs for DHAUTH.(i) Bugs in DH axiom are fixed (ii) The secrecy conditions for DHKE are proved using general inductive method (iii) Cipher text integrity assumptions based axiom reasoning are established. Computational PCL reasons directly about properties of probabilistic polynomial time execution of protocols. As formulated

Thomas Jefferson Have you ever wondered how the wheel cipher worked‚ who made it‚ and how has it helped people? Thomas Jefferson was an inventor and a president of the United States. His invention of the wheel cipher helped translate hidden words‚ improve spy work‚ and it helped soldiers receive plans in letters secretly without the enemy knowing what it meant. The effectiveness of the word cipher was due to Thomas Jefferson’s desire to learn‚ his creativity in problem solving‚ and his desire to

Locard’s Exchange Principle and the use of Fingerprints: Edmond Locard (1877-1966) was a French scientist specialised in both medicine and law. Inspired by the work of Hans Gross‚ it was Edmond that created the concept that all objects of any material should leave traces of itself upon whatever it touches‚ even if it is the minutest amount‚ simply put as “Every Contact leaves a trace‚” Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such as

3.1. Other Methods 3.1.1. Trusted Certificate Authority (CA) CAs are used to issue trusted certificates‚ digital signatures or keys to the person using it. This way we can have systems in place that’ll revoke any certificate coming from a non-trusted source (Truth‚ S‚ 2011). For example‚ an attacker may have generated their own key or certificate but it isn’t recognised as a trusted source and therefore our systems can deny it. 3.1.2.

CHAPTER 1 INTRODUCTION INTRODUCTION TO STEGANOGRAPHY Steganography is the science of writing hidden messages in such a way that no one apart from the sender and intended recipient realizes there is a hidden message. In this technique‚ a secret message is hidden within an ordinary message and the extraction of it is done at its destination. The term steganography combines the two Ancient Greek words Steganos and graphein‚ where “steganos” means “covered‚ concealed‚ or protected” and “graphein”
