What is an accurate description of an asymmetric encryption technology?
It is an encryption process that uses a public and private key pair to encrypt/decrypt data.
Which key is used to encrypt data in an asymmetric encryption system?
This answer depends on who is sending the information in a secure manner. If confidentiality is required, then the public key of the receiver is used to encrypt the message. If integrity is desired then your private key would be used to encrypt the message.
What is conventional encryption?
Conventional encryption ciphers rely on a single key for both encryption and decryption. Modern protocols will use a private key for encryption and a different public key for decryption. These two keys are mathematically related in a fashion that allows them to encrypt/decrypt the same data successfully.
Why is it necessary to use encryption when transmitting data to a scure website?
If you are communicating to a secure website via https (port 443) then the communications are encrypted by default. The use of https means a secure communication to another web server. The only way to ensure confidentiality (security) in the data transmission is to encrypt it. Since you don't know which public access lines or networks the data packet will travel through, without encryption anyone could read the information. To make that not possible, encryption is used in the data transmission.
Utilizing Public Key Encryption How would John and Jim send an encrypted message between parties?
John would use Jim's public key to encrypt and Jim would use his private key to decrypt.Public Key Cryptography (Asymmetric encryption)An algorithm where data encrypted with a public key can only be decrypted by the matching private key. Vice versa is true, what is encrypted with a private key can only be decrypted with a public key.
Which encryption process uses two keys and includes RSA as a common solution?
Type your answer here... AsymmetricAnswer Explanation: Asymmetric encryption uses a key pair, a public key, and a private key for the encryption and decryption process. One key is used to encrypt the information, and the other key is used to decrypt it. Asymmetric encryption uses Rivest Shamir Adleman (RSA) as a common asymmetric solution to encrypt information.It could be that the person posing the question was looking for SSL (or TLS) which use encryption to secure communications. While RSA is not the only encryption method accepted, both SSL and TLS can, and commonly DO, use RSA as the negotiated encryption scheme.
What is encrypting data?
Data encryption is the act of changing electronic information into an unreadable state by using algorithms or ciphers. Originally, data encryption was used for passing government and military information electronically. Over time as the public has begun to enter and transmit personal, sensitive information over the internet, data encryption has become more widespread. Nowadays Web Browsers will automatically encrypt text when connecting to a secure server. You can tell you are on a secure, encrypted website when the URL begins with "https", meaning Hypertext Transmission Protocol, Secure.
What is symmetric and asymmetric?
From another user: Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric.
Public key encryption is also known as asymmetric encryption?
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
What is the meaning of asymmetric encryption?
Asymmetric Encryption is a form of Encryption where keys come in pairs. What one key encrypts, only the other can decrypt. Frequently (but not necessarily), the keys are interchangeable, in the sense that if key A encrypts a message, then B can decrypt it, and if key B encrypts a message, then key A can decrypt it. While common, this property is not essential to asymmetric encryption. Asymmetric Encryption is also known as Public Key Cryptography, since users typically create a matching key pair, and make one public while keeping the other secret. Users can "sign" messages by encrypting them with their private keys. This is effective since any message recipient can verify that the user's public key can decrypt the message, and thus prove that the user's secret key was used to encrypt it. If the user's secret key is, in fact, secret, then it follows that the user, and not some impostor, really sent the message. Users can send secret messages by encrypting a message with the recipient's public key. In this case, only the intended recipient can decrypt the message, since only that user should have access to the required secret key. The key to successful use of Asymmetric Encryption is a Key Management system, which implements a Public Key Infrastructure. Without this, it is difficult to establish the reliability of public keys, or even to conveniently find suitable ones.
What kind of encryption uses the concept of public keys?
Asymmetric encryption employs the use of public/private key pairs.
Why do you use passwords to generate keys for encryptions?
i stored some private files on my usb drive, and i don't want others to view them when i misplaced or lost it. So i use usb drive encryption softwrare to encrypt it. The encryption appliaction allows me to add password to protect it. You use passwords as a means of generating keys because encryption techniques require a key to either encrypt or decrypt the information. This may be a secret private key or a public key (or both), depending on what you want to do with the information, either provide confidentiality or integrity. Without the password key the receiver would not have a means of decoding the message.
