FIELD: information technology.
SUBSTANCE: processor for providing functional capabilities of cipher hashing cycle includes a decoding stage for decoding the first command for executing cipher protected hashing algorithm using triple data encryption standard (TDES), while the first command indicates the source data and one or more key operands, and one or more hardware executing units configured in response to the decoded first command to execute primary exchange over the source data for generating the source data, subjected to exchange, to execute one or more cyclic iterations of cipher protected hashing algorithm over the source data, subjected to exchange, using one or more key operands to generate the encrypted data, while one or more cyclic iterations is less than 16, as indicated by the first command, to execute reverse primary exchange over the encrypted exchange data and to save the execution result of the first command in the recipient register, while the first command indicates the recipient register with the operand of the recipient register with one command and a plurality of data (SIMD).
EFFECT: providing functional capabilities of a cipher protected hashing cycle.
