🛡️Information Security: Asymmetric Encryption (Definitions)

"Requires a pair of keys to encode and decode information. One key is used to encrypt the plain text, and a second key, which is part of the matched pair, is used to decrypt that cipher text." (Marilyn Miller-White et al, "MCITP Administrator: Microsoft® SQL Server™ 2005 Optimization and Maintenance 70-444", 2007)

"Asymmetric encryption is an encryption model in which the encryption and decryption processes use different keys. Modern asymmetric encryption algorithms are based on the public key/private key pairs, in which the encryption and decryption keys are different but nontrivially related. The public key is widely known and distributed for encryption while the private key is kept secret and used for decryption. Although the keys are related, it is considered infeasible to try to derive the private key from the public key." (Michael Coles & Rodney Landrum, , "Expert SQL Server 2008 Encryption", 2008)

"Asymmetric encryption is encryption that requires two different keys: one to encrypt data and another to decrypt it. The most common form of asymmetric encryption is public key encryption, in which the two keys are mathematically related." (Michael Coles, "Pro T-SQL 2008 Programmer's Guide", 2008)

"Asymmetric encryption, also known as public-key encryption, is a form of data encryption where the encryption key (also called the public key) and the corresponding decryption key (also called the private key) are different. A message encrypted with the public key can be decrypted only with the corresponding private key. The public key and the private key are related mathematically, but it is computationally infeasible to derive the private key from the public key. Therefore, a recipient could distribute the public key widely." (Ninghui Li, "Asymmetric Encryption", 2009)

"Encryption that requires two different keys: one to encrypt data and another to decrypt it. The most common form of asymmetric encryption is public key encryption, in which the two keys are mathematically related." (Miguel Cebollero et al, "Pro T-SQL Programmer’s Guide" 4th Ed., 2015)

"Public-key cryptography refers to a cryptographic system requiring two separate keys, one of which is secret and one of which is public. Although different, the two parts of the key pair are mathematically linked. One key locks or encrypts the plaintext, and the other unlocks or decrypts the cipher text. Neither key can perform both functions by itself. The public key may be published without compromising security, while the private key must not be revealed to anyone not authorized to read the messages."
