Abstract
In some aspects, an encryption method comprises encrypting a first portion of a message using a first secret key. The first secret key is generated based on the public key of an entity. A one-way function is used to generate a second secret key from the first secret key, and the first secret key is subsequently discarded. A second portion of the message is encrypted using the second secret key. The encrypted first portion of the message and the encrypted second portion of the message are provided to the entity.
