Embodiment Construction

[0014] In the following description, reference is made to the accompanying drawings, which form a part hereof, and which show several embodiments of the invention. It is to be understood that other embodiments may be utilized and structural and operational changes may be made without departing from the scope of the present invention.

[0015] Figure 1 shows details of a computing architecture according to certain embodiments. The automated data storage library 100 includes a library controller 110, data storage drives 120a...120n (e.g., tape drives), and media inserted into the data storage drives 120a...120n, such as data storage media 124a... 124n. Each data storage drive 120a...120n is loaded with a data storage medium 124a...124n (eg, a magnetic tape cartridge). The data storage drives 120a...120n enable the reading of information from and the writing of information to the data storage media 124a...124n (eg, magnetic tape cartridges). It should be understood that in the...

Abstract

Provided are techniques for key generation and retrieval. Unique identifiers of two or more key servers are stored, wherein each key server is capable of generating keys for encryption of data and of returning keys for decryption of data. A key request is received. A technique for selecting one of the key servers to which the key request is to be forwarded is identified. One of the key servers isselected using the identified technique. The key request is sent to the identified key server.

Description

technical field [0001] Embodiments of the invention relate to key generation and retrieval using a key server. Background technique [0002] Automated data storage libraries (eg, tape libraries including tape drives) are known for providing cost-effective storage and retrieval of large amounts of data. Data in an automated data storage library is stored on data storage media (e.g., magnetic tape cartridges), which in turn are stored in storage slots (or storage slots) inside the library by rendering the data storage media and its resident data. shelf, etc.), where they are accessible for physical retrieval. Accessors may be used to move data storage media (eg, tape cartridges) between storage slots and data storage drives (eg, tape drives). Such data storage media are often referred to as "removable media." Data storage media may include any type of media that can store data and that can be used as removable media, including but not limited to magnetic media (such as magn...
