Secure, anonymous and unobservable communication is becom ing increasingly important due to the gradual erosion of pri vacy in many aspects of everyday life. This prompts the need for va rious anonymityand privacy-enhancing techniques, e.g., group signatures, anonymous e-cash and secret handshakes. In this paper, we investigate an interesting and practical c ryptographic construct – Oblivious Signature-Based Envel op s (OSBEs) recently introduced in [15]. OSBEs are very useful in an onymous… CONTINUE READING
