Abstract
The Escrowed Encryption Standard (EES) proposed by U.S. government has gained much attention in the last two years. It was claimed that EES can provide cryptographic protection to unclassified, sensitive data, while at the same time, allow for the decryption of encrypted messages when lawfully authorized. Later, some criticism was proposed to reveal the weakness of the EES proposal.
In this paper we propose a new key escrow cryptosystem. The system eliminates many known weaknesses of the EES proposal. Particularly, the new system strengthens the weakest part of the EES proposal, i.e., the checksum generation, and provides other benefits that the original EES proposal did not have.
