Is A function with a graph that is symmetric about the origin an even function?
An even function is symmetric about the y-axis. If a function is symmetric about the origin, it is odd.
Prove that a matrix which is both symmetric as well as skew symmetric is a null matrix?
Let A be a matrix which is both symmetric and skew symmetric. so AT=A and AT= -A so A =- A that implies 2A =zero matrix that implies A is a zero matrix
What is the symmetric property?
A relation ~ is symmetric ifX ~ Y if and only if Y ~ X.This may seem trivial, but it is easy to see that "is less than" or "is a factor of" are not symmetric.
If the mean of a symmetric distribution is 130 which of these values could be the median of the distribution?
If it is a symmetric distribution, the median must be 130.

Is DES symmetric or asymmetric cryptography?

Which symmetric cryptography solution uses a block size of 64 bits and a key size of 168 bits?
3DES
What are the different types of cryptography?
There are 2 types of cryptography such as: 1- Symmetric-key or Secret key Cryptography 2- Asymmetric-key or Public key Cryptography
What the the different types of cryptography?

Which is not a disadvantage of symmetric cryptography speed no true means to authenicate the sender or breaking one key compromises multiple parties?
The option that is not a disadvantage of symmetric cryptography is "speed." In fact, symmetric cryptography is generally faster than asymmetric cryptography because it uses simpler algorithms and smaller key sizes for encryption and decryption. The other options—lack of true sender authentication and the risk of compromising multiple parties if one key is broken—are indeed disadvantages of symmetric cryptography.
Which is not a disadvantage of symmetric cryptography in IA?
Math algorithms are complex and can easily be broken
Does symmetric cryptography use the same key to encrypt and decrypt a message?
Yes
How asymmetric cryptography both requires and support the use of symmetric cryptography?
Lmfao - do Richard kays coursework by yourself instead of asking others to answer it for you.
What is a disadvantage of symmetric cryptoghrapy?
Symmetric cryptography only requires one key for both encryption and decryption and therefore in some cases are a issue.
What are the steps involved in symmetric cryptography Also explain key management in conventional cryptography using some example?
following steps are involved in symmetric cryptography 1- sender creates a ciphertext message by encrypting the plain text message with a symmetric encryption algorithm and a shared key. 2- the sender sends the ciphertext message to the recipient. 3- the recipient decrypts the ciphertext message into plain text with a shared key.
What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
What statement relating to access control is accurate?
Symmetric cryptography is impractival when a large group is involved.
What is the two types of cryptography?
Three methods of cryptography are Substitution (substituting one symbol for another), Transposition (rearranging the order of the characters), and Steganography (hiding the existence of the message).
What kind of cryptography?
Cryptography can be broadly categorized into symmetric and asymmetric cryptography. Symmetric cryptography uses the same key for both encryption and decryption, making it fast but requiring secure key distribution. Asymmetric cryptography, on the other hand, employs a pair of keys: a public key for encryption and a private key for decryption, enhancing security but typically being slower. Additionally, there are other forms like hash functions and digital signatures, each serving specific purposes in securing data and communications.
What is a disadvantage of symmetric cryptography?
In symmetric key encryption there is one key that is shared with the person you want to share with your data. The largest disadvantage is that you have to make sure that the key remain secret.
What does the word symmetric encryption mean?
The term "symmetric encryption" refers to a form of computerized cryptography that uses a singular encryption key to guise an electronic message so that it can be sent in a secure manner.
Which is not a disadvantage of symmetric cryptography a. Speed b. No true means to authenticate the sender c. Breaking one key compromises multiple parties d. Math algorithms are complex and can easil?
d. Math algorithms are complex and can easily be broken is not a disadvantage of symmetric cryptography. In fact, symmetric cryptography typically involves simpler mathematical operations that allow for fast encryption and decryption. The other options highlight significant drawbacks, such as the speed of encryption, lack of sender authentication, and the risk of compromising multiple parties if a single key is broken.
How is cryptography used?
Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
What is symmetric cryptography?
There are two general types of modern cryptography; symmetric cryptography and asymetric (also known as public key) cryptography. Symetric crypto is where both sides have the same shared encryption key, and that key is used to both encrypt and also decrypt any encrypted information. Symmetric crypto is more efficient (faster) than asymmetric crypto, but asymetric crypto works without having to share a key.
How many different keys will be required to give four people the ability to encrypt and decrypt the message using a symmetric cryptography algorithm?
ONEAnswer Explanation: Only one key would be required for everyone to be able to encrypt and decrypt the message. Symmetric cryptography uses the same "shared secret" key for encrypting and decrypting a message. A message encrypted using a symmetric encryption algorithm can be decrypted by anyone with the key. For this reason it is very important to ensure that the key is protected from unauthorized use. One of the primary security issues surrounding the use of symmetric cryptography is the method used to transport the key to users who need it, as most forms of communication are susceptible to eavesdropping.
