Abstract: A system, computer product and method is provided for PKI enabled data communication at a browser. A PKI enabled browser is loaded one or more network-connected device. The PKI enabled browser requests a web page from a web server. The web page is downloaded to the PKI enabled browser. The PKI enabled browser includes a PKI operation module which conducts one or more PKI operations corresponding to the particular web page downloaded. These operations may include encrypting data, decrypting data, authenticating data, or verifying digital signatures. The invention permits PKI enabled posting of data to a remote computer, including from a wireless device, as well as PKI enabled retrieval of data at a computer from a remote computer, including at a wireless device. The PKI enabled browser of the invention is supported by a web server that includes a web application that facilitates PKI enabled data transactions at the PKI enabled browser.

Abstract: An encryption/decryption system for providing restricted use of each key in a plurality of keys to preserve confidentiality of the plurality of keys. Each key is usable by an associated user in a public key infrastructure to encrypt and decrypt data. The encryption/decryption system comprises a key storage means for storing a plurality of keys, user authentication means for determining whether a prospective user of a key in the plurality of keys is the associated user of the key, and an encryption/decryption means for encrypting and decrypting data using the plurality of keys when the user authentication means authenticates the prospective user. The encryption/decryption means is operable in a browser on a client computer.
