According to one embodiment, a method for implementing secure key management is provided. The method includes populating a section of information associated with a key, the section being populated with information relating to how the key was created. The method also includes populating the section with information relating to how the key was acquired by a secure module; and binding the section to the key, wherein the key is encrypted.

Secure key management

According to one embodiment, a method for implementing computer security is provided. The method includes creating a token and populating a payload section of the token with key material and selecting a wrapping method that specifies how the key material is securely bound to key control information, wherein a structure of the key control information in the token is independent of the wrapping method. The method also includes wrapping the key material and binding key control information to the key material in the token, wherein the key control information includes information relating to usage and management of the key material.

A system for implementing computer security is provided. The system includes a computer processor and an application configured to execute on the computer processor, the application implementing a method that includes creating a token and populating a payload section of the token with key material and selecting a wrapping method that specifies how the key material is securely bound to key control information. A structure of the key control information in the token is independent of the wrapping method. Implementing computer security also includes wrapping the key material and binding key control information to the key material in the token. The key control information includes information relating to usage and management of the key material.

Embodiments relate to wrapping of a common cryptographic architecture (CCA) key token. An aspect includes wrapping, by an exporting computer, the CCA key token using a key wrapping export function, the CCA key token comprising a CCA key data section and an unencrypted control vector. Another aspect includes splitting the control vector into a first control vector portion and a second control vector portion. Another aspect includes encrypting the CCA key data section and the first control vector portion using an key encrypting key (KEK) to generate a wrapped key block. Another aspect includes binding the second control vector portion to the wrapped key block to form an associated data section, wherein the associated data section is not encrypted, and wherein the wrapped key block and the associated data section comprise a wrapped key token.

Secure key management includes populating a section of information associated with a key, the section of information being populated with information relating to a level of protection of the key accumulated over time. Secure key management further includes securely binding the section of information to the key, wherein the key is encrypted.

A computer program product for secure key management is provided. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for creating a token and populating the token with key material, and binding key control information to the key material. The key control information includes information relating to usage of the key material populating one or more key usage fields that define attributes that limit actions that may be performed with the key material.

Key usage policies for cryptographic keys

A computer program product for secure key management is provided. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for creating a token and populating the token with key material, and binding key control information to the key material. The key control information includes information relating to management of the key material populating one or more key management fields that define attributes that limit distribution of the key material.

A system for creating a secure key is provided that includes a computer processor and an application configured to execute on the computer processor, the application implementing a method that includes creating a token and populating a key control information section of the token with a value to indicate a minimum number of key parts used to form a key. Creating the secure key also includes populating a payload section of the token with a first key part, binding the key control information section to the payload section, adding a second key part to the first key part and iterating the value and binding the key control information section to the payload section after the second key part has been added. Creating the secure key further includes indicating the key is complete, wherein the key comprises a combination of the first and second key parts.
