What is a trapdoor function?
 
04:06
Modern cryptography depends on the existence of several special kinds of mathematical functions. One important kind is a trapdoor function. Trapdoor functions are somewhat similar to hash functions in that they are easy to compute but hard to invert…​ except if you know a secret piece of information. So if someone does not have the secret or key, they cannot invert the function. If they do, they can open the trapdoor and invert the function. Trapdoor functions form the basis of modern cryptographic techniques that are widely-used online.

When used in conjunction with American National Standards Institute (ANSI) X9.52 standard, this publication provides a complete description of the mathematical algorithms for encrypting (enciphering) and decrypting (deciphering) binary coded information. Encrypting data converts it to an unintelligible form called cipher. Decrypting cipher converts the data back to its original form called plaintext. The algorithms described in this standard specifies both enciphering and deciphering operations which are based on a binary number called a key computer security cryptography data encryption standard animation

Extracting Speed Spectrum Hidden Data From Digital Media
 
01:24
Title: Extracting Spread-Spectrum Hidden Data from Digital Media Domain: Networking - Steganography Key Features: 1. We consider the problem of extracting blindly data embedded over a wide band in a spectrum (transform) domain of a digital medium (image, audio, video). We develop a novel multicarrier/ signature iterative generalized least-squares (M-IGLS) core procedure to seek unknown data hidden in hosts via multicarrier spread-spectrum embedding. 2. Neither the original host nor the embedding carriers are assumed available. Experimental studies on images show that the developed algorithm can achieve recovery probability of error close to what may be attained with known embedding carriers and host autocorrelation matrix. 3. We propose the information hiding concept to reduce the risk of using cryptographic algorithms alone. Data hiding techniques embed information into another medium making it imperceptible to others, except for those that are meant to receive the hidden information and are aware of it presence. 4. It focuses on methods of hidden data in which cryptographic algorithms are combined with the information hiding techniques to increase the security of transmitted data. We focus our attention on the blind recovery of secret data hidden in medium hosts via multi-carrier/signature direct-sequence spread-spectrum transform domain embedding. MODULE DESCRIPTION Steganography: Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol Digital steganography can hide confidential data (i.e. secret files) very securely by embedding them into some media data called "vessel data." The vessel data is also referred to as "carrier, cover, or dummy data". In Steganography images used for vessel data. The embedding operation in practice is to replace the "complex areas" on the bit planes of the vessel image with the confidential data. The most important aspect of Steganography is that the embedding capacity is very large. For a 'normal' image, roughly 50% of the data might be replaceable with secret data before image degradation becomes apparent. Multi-Carrier Spread Spectrum Embedding: The technique of spread spectrum may allow partly to fulfill the above requirements. Advantages of spread spectrum techniques are widely known: Immunity against multi-path distortion, no need for fiequency planning, high flexibility and variable data rate transmission. The capability of minimising multiple access interference in direct-sequence code- division-multiple-access system is given by the cross-correlation properties of spreading codes. In the case of multi-path propagation the capability of distinguishing one component fiom thers in the composite received signal is offered by the auto-correlation roperties of the spreading codes. Image encryption and watermarking: The host image is an 8-bit or higher grey level image which must ideally be the same size as the plaintext image or else resized accordingly using the same proportions. Pre-conditioning the cipher and the convolution processes are undertaken using a Discrete Fourier Transform (DFT). The output will include negative floating point numbers upon taking the real component of a complex array. The array must be rectified by adding the largest negative value in the output array to the same array before normalization. For color host images, the binary cipher text can be inserted into one or all of the RGB components. The binary plaintext image should have homogeneous margins to minimize the effects of ringing due to 'edge effects' when processing the data using Fourier transform. Image decryption and extraction: (i) The correlation operation should be undertaken using a DFT. (ii) For color images, the data is decomposed into each RGB component and each 1-bit layer is extracted and correlated with the appropriate cipher. (iii) The output obtained in Step 3 has a low dynamic range and therefore requires to be quantized into an 8-bit image based on floating point numbers within the range max (array)-min (array).

This time we attack greedy.c!!! About CS50. CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike, with or without prior programming experience. An entry-level course taught by David J. Malan, CS50 teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. Languages include C, Python, SQL, and JavaScript plus CSS and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. As of Fall 2016, CS50, was Harvard's largest course. The Deliberate Think LIVE Show is an attempt to help students get the feel of the PROCESS and the struggle of conquering technical stuff like computer science and mathematics. We solve problems that we have SEEN FOR THE FIRST TIME. (All material used belong to their respective owners. FAIR USE) Here at Deliberate Think we believe that it's just not enough to sit in classrooms, watching lectures or cramming right before an exam. There is no short-cut to actually putting in the work. Conquering technical material needs a lot of work. But it doesn't have to be overwhelmingly painful. The key is to do it ONE STEP AT A TIME.

Gung Ho! - Packets Don't Lie (Bob loves Alice)
 
03:37
Bob learns that life is a test and, THERE IS MATH ON THE TEST! His love for Alice must withstand the most modern of trials. First, before he can lock up secret messages to her, he must first give her the secret key to the lock. How? He can't lock that up. He must also realize that there are somethings, Alice will never share (nor should she, to protect her most vital interests). Finally it is likely impossible to determine what is true, but Bob learns that he can prove what is false. Good luck to our heroes Bob and Alice. The future of the world depends on people like you two. There is evil in this world that will spy, lie and cheat. No one is invulnerable to these challenges. But good will always triumph over evil. Gung Ho! For over 30 years, like Jedi Knights, have been defending the world from the forces of evil. A Nebulazone hookup. Produced by Otto Capobianco Labs (optional) Prerequisites: computer with Wireshark, web browser(s) and an internet connection. Lab1) Sniff the SSL handshake. Start capturing and open a session to an SSL site, e.g. Gmail. After you get the HTTPS in the URL, stop the capture. Filter on SSL and examine the Client Hello (try capture filter "ssl.handshake.type"). How many cipher suites does your browser support? Identify which symmetric, asymmetric and hashing algorithms are used in cipher spec 0x000005. Lab2) Examine the Server Hello. What cipher spec did the server negotiate? What algorithms make up the cipher spec? Lab3) Examine the Server's certificate and answer the following questions: Who signed the certificate? What hashing and asymmetric algorithms are used in the signature? Where is the CRL for this certificate? Does this certificate support OCSP? Lab 4) Filter on OCSP. How did the client identify the certificate in question? Who signed the response? EXTRA CREDIT! Change browsers and repeat the above. How many differences do you see? Did you expect that many?
