METHOD AND APPARATUS TO ROTATE DATA ENCRYPTION KEYS IN DATABASES WITH NO DOWN TIME

摘要

A database includes a first instance and a second instance. The first and second instances of the database are encrypted with a first encryption key and have content that is synchronized. Database queries from a user computing device are directed to the first instance of the database. A third instance of the database is created from one of the existing two instances of the database. The third instance is decrypted from the first encryption key and is encrypted with a second encryption key. Database queries from the user computing device are redirected from the first instance of the database to the third instance of the database without interrupting service to the user computing device. The process is repeated by creating additional instances of the database, encrypting the additional instances with new encryption keys, and by redirecting database queries to the additional instances of the database.
