What is a secure encryption?
Encryption is a process of translating a message from the Plaintext, into an encoded message, called the Ciphertext. This is usually accomplished using a secret Encryption Key and a cryptographic Cipher. ss of translating a message, called the Plaintext, into an encoded message, called the Ciphertext. This is usually accomplished using a secret Encryption Key and a cryptographic Cipher.
What are three broad categories of applications of public-key cryptosystems?
Encryption/decryption, Digital signature and Key exchange
The combination of a public key and a private key is known as a?
This is known as RSA encryption. Encryption involving a public and private key combination is known as asynchronous cryptography, as opposed to synchronous cryptography. It is also known as public key cryptography. RSA is an algorithm that may be used (but there are others that can be used), in public key cryptography. (A key pair)
Which fields are required within digital certificates in a public key infrastructure?
Type your answer here... Serial Number and IssuerAnswer Explanation: Digital certificates in a PKI have nine required fields, two of which are the Serial Number and Issuer fields. The Serial Number is an identification number for the certificate. The name of the organization that issued the certificate is required in the Issuer field. Other required fields include the following: Version, Algorithm ID, Validity, Subject, Subject Public Key Info, the digital signature of its issuer, and an algorithm identifier.
How does Public Key Encryption work?
The exact mathematics of the encryption differ depending on the algorithm used, but in principle, this is how it works. An algorithm is used to generate a pair of keys that are related mathematically. In many cases they are factors of a very large number. One of the keys is the Public key, which is published to a key registry. The other is the Private key which is held by the owner alone. The important thing is that it is supposed to be impossible to derive the Private key from the Public key. When the owner wants to send a message, the use the Private key to encrypt it or to sign it. Since only the corresponding Public key can decrypt it, that establishes that the sender is who they say they are (because only they should have the Private key). If the sender used their Private key to sign the message, the receiver can use the Public key verify that the message has not been tampered with. On the flip side, some can encrypt a message to the owner of the Private key by using that person's Public key. Only the holder of the Private key can decrypt the message. This can provide confidentiality. Two correspondents can establish secure communications by using each others Public keys to encrypt their messages. Often the public key is deposited with a trusted Certificate Authority. Assuming the user trusts the key repository, they can use them to authenticate the key they are using as belonging to the person it is supposed to belong to. To get more details on the mathematics of encryption and decrption using Public Key Encryption, aka asymmetric encryption. Do a web search for the particular algorithm involved, be it SSH, PGP, TLS, or some other protocol.
What are the difference between DES and RSA algorithm?
DES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in DES, while you use separate keys (public and private keys) in RSA. DES uses 56-bit keys for encryption while RSA uses 2600-bits of KEY
What is the difference between AES and RSA?
AES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in AES, while you use separate keys (public and private keys) in RSA. The strength of a 128-bit AES key is roughly equivalent to 2600-bits RSA key.
What is the best public-key cryptography algorithm and why?
RSA (Rivest, Shamir, and Adelman) is the best public key algorithm.
Which algorithm do you use to exchange shared private keys?
The diffie hellman key exchange uses prime numbers to generate an asymmetric key pair which is used to create a secure channel over which a privet symmetric key can be sent.
What is meant by SMOCK a scable method of cryptographic key management?
SMOCK is a scaleable way of managing cryptographic keys.
Which file system is specially design to provide more security?
Generally, you are referring to the class of Filesystems known as Cryptographic file systems. A crypto filesystem uses a symmetric algorithm to encode the contents of disk; it requires a special key to be able to use. Several common filesystems now support a Cryptographic mode.
Symmetric cryptographic algorithms are also called?
private key
Is knapsack algorithm is a public key encryption algorithm?
yes
Enterprise Key Management System?
JISASoftech provides the most versatile key management solutions on the market. Our key management systems, as all-in-one-box cryptographic modules, spin up individual cryptographic operations in the VirtuCrypt cloud and combine them with critical infrastructure. JISA’s key management servers handle both symmetric and asymmetric encryption.
Which key is often used to securely distribute symmetric algorithm keys?
Session key
What is the minimum number of cryptographic keys required for secure two-way communications in asymmetric key cryptography?
