asymmetric cryptographic technique
A cryptographic technique that uses two related transformations, a public transformation (defined by the public key) and a private transformation (defined by the private key). The two transformations have the property that, given the public transformation, it is computationally infeasible to derive the private transformation.
source: ISO11770-1, 1996
a cryptographic technique that uses two related transformations, a public transformation (defined by the public key) and a private transformation (defined by the private key). The two transformations have the property that, given the public transformation, it is computationally infeasible to derive the private transformation.
source: ISO15946-3, 2002
cryptographic technique that uses two related transformations, a public transformation (defined by the public key) and a private transformation (defined by the private key). The two transformations have the property that, given the public transformation, it is computationally infeasible to derive the private transformation. [ISO/IEC 11770-1:1996].

cryptographic technique that uses two related transformations - a public transformation (defined by the public key) and a private transformation (defined by the private key) - which have the property that, given the public transformation, it is computationally infeasible to derive the private transformation in a given limited time and with a given limited computing power

a cryptographic technique that uses two related transformations, a public transformation (defined by the public key) and a private transformation (defined by the private key). The two transformations have the property that, given the public transformation, it is computationally infeasible to derive the private transformation. NOTE - A system based on asymmetric cryptographic techniques can either be an encipherment system, a signature system, a combined encipherment and signature system, or a key agreement system. With asymmetric cryptographic techniques there are four elementary transformations: sign and verify for signature systems, encipher and decipher for encipherment systems. The signature and decipherment transformation are kept private by the owning entity, whereas the corresponding verification and encipherment transformation are published. There exist asymmetric cryptosystems (e.g. RSA) where the four elementary functions may be achieved by only two transformations: one private transformation suffices for both signing and decrypting messages, and one public transformation suffices for both verifying and encrypting messages. However, since this is not the general case, throughout ISO/IEC 9798 the four elementary transformations and the corresponding keys are kept separate.

cryptographic technique that uses two related operations: a public operation defined by a public data item, key or number, and a private operation defined by a private data item, key or number (the two operations have the property that, given the public operation, it is computationally infeasible to derive the private operation)
