Abstract
Methods, systems, and computer programs for using hybrid encryption schemes are disclosed. In some implementations, a random value is obtained by a pseudorandom generator. A symmetric key is generated based on the random value. A public component is also generated based on the random value. Additionally, an initialization vector is generated based on the random value. The symmetric key and the initialization vector are used to generate an encrypted message based on an input message. The encrypted message and the public component are transmitted to an entity. At least one of the public component or the symmetric key is generated based additionally on a public key of the entity.
