Abstract

The invention discloses a method and a device for calling a cipher card by JCE (Java Cryptography Extension) to implement an internal RSA secret key operation. The device comprises terminal equipment and the cipher card; the terminal equipment comprises an application module, a JCE implementation module and a cipher card management tool; the cipher card is inserted on the terminal equipment, and is connected with the cipher card management tool for storing a generated RSA secret key pair; the application module is connected with the JCE implementation module for sending the RSA secret key pair lead-out or RSA secret key operation request; and the JCE implementation module is connected with the cipher card for sending the processed RSA secret key pair lead-out request or RSA secret key operation request to the cipher card, and the cipher card responds to the request of the JCE implementation module. The method and the device which are disclosed by the invention achieve an effect that the JCE calls an RSA secret key stored in the cipher card to carry out the secret key operation, and ensure safety storage of a private key and safety of communication.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and a device for JCE calling a cipher card to realize built-in RSA key calculation. Background technique [0002] Java is an object-oriented programming language that can write cross-platform application software. It is an assembly of the Java programming language and the Java platform launched by Sun Microsystems in May 1995. Java technology has excellent versatility, efficiency, platform portability and security, and is widely used in personal PCs, data centers, game consoles, scientific supercomputers, mobile phones and the Internet. In the industrial environment of global cloud computing and mobile Internet, Java has more significant advantages and broad prospects. [0003] The Java platform defines a set of APIs that span major security areas, including cryptography, public key infrastructure, authentication, secure communication, and access control. ...
