Claim 14:
15. A method comprising:
parsing input data to be encrypted, the parsing to determine a combination of two or more context values from the input data;
mapping a first key identifier to a first context rule defined for a first one of the two or more context values, and generating a first key corresponding to the first key identifier;
mapping a second key identifier to a second context rule defined for a second one of the two or more context values, and generating a second key corresponding to the second key identifier;
mapping a third key identifier to a combination of context rules defined for the combination of two or more context values, and generating a third key corresponding to the third key identifier, the combination of context rules including the first context rule and the second context rule; and
encrypting the input data based on the third key to obtain encrypted data.
