Abstract
A method of encrypting data is disclosed. The method comprises determining, at a first node associated with a first public-private key pair of a cryptography system having a first private key (V) and a first public key (P), a common secret (S) common with the first node and a second node, wherein the second node is associated with a second public-private key pair of the cryptography system having a second private key (V) and a second public key (P). The common secret is determined on the basis of the first private key and the second public key, and the properties of the cryptography system are such that the common secret can be determined on the basis of the second private key and the first public key. An encryption key, based on the common secret, is determined for encryption of data (M), and the data is encrypted on the basis of the encryption key, wherein the step of encrypting data includes an exclusive or (XOR) operation.
