1. A method comprising:

  • initializing a pseudo-random number generator (PRNG);

    obtaining local seeding information from a host;

    securely obtaining additional seeding information from one or more remote entropy servers using a secure entropy collection protocol, wherein the secure entropy collection protocol to perform;

    generating a key pair including, a temporary asymmetric public key and a temporary asymmetric private key, encrypting the temporary public key with a public key associated with a remote entropy server, decrypting the temporary public key with a private key associated with the remote entropy server, encrypting the additional seeding information with the temporary public key, and decrypting the additional seeding information with the temporary private key; and

    stirring the PRNG with the local seeding information and the additional seeding information.
