Definition Edit

An asymmetric algorithm is

a cryptographic algorithm using different, mathematically-related keys for encryption and decryption.[1]
[a]n algorithm for performing encipherment or the corresponding decipherment in which the keys used for encipherment and decipherment differ.[2]

Overview Edit

"With some asymmetric cryptographic algorithms, decipherment of ciphertext or the generation of a digital signature requires the use of more than one ]]private key]].[3]

"Asymmetric algorithms are poorly suited for encrypting large messages because they are relatively slow. Instead, these algorithms are used to achieve authentication, integrity and non-repudiation, and support confidentiality through key management. Asymmetric algorithms are used to perform three operations: digital signatures, key transport, and key agreement."[4]
