4. Strong collision: given a message M1, it is not possible to find two distinct messages such that h (M1’) = h (M1). The probability of this collision is 2n/2.
Hash function is used in message authentication which uses a secret code before hashing so that no one else can modify the message and hash and then can encrypt the message for confidentiality. There are several ways of applying hash for message authentication:
1. One is to apply hash to the message and encrypt it and decrypt it using the same key.
2. Hash is applied to the message and encrypted now the encrypted hashed message and message is sent to the receiver and the receiver decrypts it using the same key
3. Hash is applied to the message and encrypted using the sender’s public key now the encrypted hashed encrypted message and the message is

Secret code is applied to the message and hashed and is sent to the receiver
6. Secret code is applied to the message and hashed and this hashed message is encrypted and sent to the receiver.
It is used in digital signatures the hash is encrypted using sender’s private key and then encrypted using public key and sent to the receiver and the receiver decrypts the message using the private key. It is used in password storage A good system does not store the plaintext equivalent but store something else which include some randomness .so now if we use hash and because of its onewayness it is impossible to get back the password. If we use pure hash in the password and encrypt it, it can be broken easily by exhaustive search so that is why we have add some randomness to the password before the hash function is applied. The randomness is stored with the password hash. So now instead of pure hash and pure password we store the hash o/p of password chosen by me and some random number chosen by the system. From now whenever we use the password the system associates with the random number and gives access. This is how a hash is used in password storage.

There was a heavy downpour of rain and the driver of Vehicle 1 did not see Pedestrian 1 crossing Fletcher Avenue. Pedestrian 1 was walking southbound across Fletcher Avenue, in or near the marked crosswalk, on the west side of 22nd Street. Pedestrian 1 was walking against the “Do Not Walk” signal, for pedestrian traffic.
Once, the current rating and voltage rating are chosen, one needs to look at the data sheet of the connector to check whether it meets the given specifications. In the datasheet, one should look at the test procedure used to arrive at the specifications and check whether it meets the test standard. Not everyone uses the same testing criteria, so ensure you understand how these specifications were derived. It should also be confirmed that the contact will support the conductor size that has been chosen. A non-compatible conductor could cause overheating issues, leading to premature connector failure.
Multilinear principal component analysis (MPCA) is a mathematical procedure that uses multiple orthogonal transformations to convert a set of multidimensional objects into another set of multidimensional objects of lower dimensions. There is one orthogonal (linear) transformation for each dimension (mode); hence multilinear. This transformation aims to capture as high a variance as possible, accounting for as much of the variability in the data as possible, subject to the constraint of mode-wise orthogonality. MPCA is a multilinear extension of principal component analysis (PCA).

subsection{Recommending Unexpected Relevant Items} Once the forgotten items have been identified, we need to distinguish relevant ones from the rest. Given user taste shifts, as well as the changes in the system as a whole, not all unexpected items remain relevant, and consequently useful for recommendation. The key concept to identify relevant items is the extbf{relevance score} of the items at each moment. We propose four strategies to define the relevance score of each unexpected item.
The computer I have chosen for Adam is a custom gaming PC called The Rebel T3. The computer I have chosen for Adam is from NCIX (ncix.com) costing $4,276.86 CAD, including tax and shipping. The computer may seem a lot, however, the cost for the specifications is justifiable for what Adam requires. Since Adam enjoys running multiple operating systems, the computer will come with Windows 10 Home and will provide different operating systems such as Linux and Mac OS X. The CPU is an Intel core i7-6700K with quad core at 4.2Ghz.
Liven up your living space with a range of patio designs The current trend of making your home look better is catching on and there are many people who have joined the bandwagon and it is quite easy to see why the people are getting so hooked into this trend because as we know reconstruction expenses on a house are enormous and no matter what the finance company may tell you that it adds value to your house, the end result is that it takes a lot of time and effort just to build up a few thousand dollars, in turn, people have now taken up a less expensive and effective way to expand their homes with the use of a simple patio which is now becoming very quickly adopted throughout the suburban neighbourhoods and this has given rise to a whole new range of patio designs as well as more and more people adopt the trend. In basic, the patio is made up of
The encryption key (public key) does not have to be secret and anyone can use it to encrypt data. However, the corresponding decrypted key (private key) is known to a single entity that can decrypt data encrypted with the encryption key. When we need to send an encrypted message to someone else, we first obtain the person’s public encryption key and transform the message with it. Only the recipient knows the corresponding private key. The recipient can decrypt the message.
After compiling all of the ingredients into a numbered list, I find out that every product “purchased” at Harris Teeter would account for $116.19 over the budget. The few adjustments I made to my shopping list beforehand did not help reduce the total to a reasonable price either. While I was going through all of the products at home, I crossed out a few unnecessary items that were optional or switched to products with a lower price just to see if I could be within the budget. Eventually, after I was done “shopping” and tallying up all of the prices, the cost still exceeded the price that I calculated in my head. As I went down the aisles searching for foods on my grocery list, I kept a close eye out for products that had nutritious labels such as organic, fresh, or low in sodium so that the college student I chose could receive the right amount of nutrients needed for a healthy lifestyle.
Network internet layer This can be used to set the border line of what people can think of about the network. With this layer it will be able to interconnect with networks and will decide how the layers can do this process. It will be able to can concentrate and determine how the data will get from one remote network to the computer. Also it will take care with devices which are local. This is mainly tasked to take care of is routing which allows data to be moved the data across the series of networks which are connected.
We take the character which is different and convert the character into binary format. We use this differed character to embed our secret message which is also converted into binary format. Then binary value of the secret message and the cover text is compared to find matching substring in the string. If it is not matched then we eliminate the last bit of the secret message and continue the process until we find matching substring in the string. When the matching pattern is found we create a matrix file with word number, starting delimiter and ending delimiter which acts as key for retrieving the secret
An algorithm is a process or set of rules to be followed in calculation or other problem-solving operations, especially by a computer. One of the algorithms for encrypting information is called the symmetric-key or single key algorithm. It has this name because both, the encrypting and decrypting process are mirror opposites of each other. This method requires both, the receiver and the sender to have the same encryption key. Since both of them have the encryption key, they can write their plaintext and translate cipher text and whoever needs to read the cipher text can just use the encryption key to translate the cipher text to readable plaintext.
Cryptography basically makes any transaction secure between two parties. Security is very important, because every person with Bitcoins, their Bitcoins, and every transaction is logged to a public ledger visible by every computer on the
This code is used for Emergency Signaling (SOS) for all kinds of receivers. This code can also be used by the people with several disabilities. The Morse code is mostly used by the hams because they ensure systematic transmission of the signals. However, it is not very easy to learn these codes.
