Common use of Key Escrow Clause in Contracts

Key Escrow. The trusted authority is the key escrow entity and must be well protected. The TA is able to obtain all of the keys and decipher all previously recorded messages. This may be a desirable feature within some organisations. In the BYka scheme, the master keys generation and storage can be dispersed among a committee of TA’s. In this way, protection against some rouge TA’s is possible, since they must all work together to generate the full set of keys.
