Abstract
Techniques are provided for encryption technique rotation using input/output (I/O) operations. One method comprises obtaining an I/O request to write designated data to a storage device, wherein at least some of the existing data stored by the storage device prior to the obtaining is protected using a first encryption technique associated with a first time period; protecting the designated data using a second encryption technique associated with a second time period that is subsequent to the first time period; and writing the protected designated data to a sector of the at least one storage device. The sector may be marked as comprising re-encrypted data. For an I/O request to read data, a determination is made as to whether the requested read data is stored in a sector comprising re-encrypted data; and the requested read data is decrypted using a decryption key obtained based on a result of the determining.
