Unknown (2006 film)

Unknown is a 2006 American mystery thriller film directed by Colombian filmmaker Simon Brand and starring Jim Caviezel, Greg Kinnear, Bridget Moynahan, Joe Pantoliano and Barry Pepper about a group of men kidnapped and locked in a factory with no memory of how they arrived there. Piecing together information around them, they realize that some were kidnapped and some were the kidnappers. They decide they must work together to figure out how to get away before the gang that captured them returns.

The film was previewed before a theater audience for the first time in New York City on December 13, 2005.

Plot

In an abandoned warehouse, a handful of men slowly regain consciousness, but they have amnesia and have no idea who they are, where they are, or what has happened to them. All five seem to have been in some sort of serious scuffle; one is tied up on a chair (Joe Pantoliano), another has been handcuffed and shot (Jeremy Sisto), a third has a broken nose (Greg Kinnear), and the other two have their share of scrapes and bruises (Jim Caviezel and Barry Pepper). Everyone is asleep at the start. Caviezel's character wakes up first. He checks to make sure everyone is alive and then decides to walk around and try to find out what is going on. He discovers that all the windows have bars over them and the only door has a mechanized lock. He finds a ringing phone and picks it up. The caller asks what is going on and Caviezel tells the caller that everyone is fine. The Caller tells him he will be back in a few hours. Meanwhile, somewhere else a money drop off is going down. Mr. Coles has been kidnapped.

Jun Kazama

Jun Kazama (風間 準, Kazama Jun) is a fictional character from the Tekken fighting game series, who has made her debut in Tekken 2, her only canonical appearance to date. Following an ambiguous relationship with Kazuya Mishima, she became the mother of Jin Kazama, both of whom are main characters in the series. She is also related to Asuka Kazama and her father.

A nature lover and the mother of Jin Kazama, Jun plays an important role in the story despite of her absence for most of the series. While she was cut from the main series after her debut, Jun has continued to appear in the series' spin-offs, including the Tekken Tag Tournament series, where her alter-ego, Unknown serves as the final boss in all Tag Tournament entries so far. Despite her relatively few appearances, the character has gained a considerable popularity among the fans of the series.

X.509

In cryptography, X.509 is an ITU-T standard for a public key infrastructure (PKI) and Privilege Management Infrastructure (PMI). X.509 specifies, amongst other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.

History and usage

X.509 was initially issued on July 3, 1988 and was begun in association with the X.500 standard. It assumes a strict hierarchical system of certificate authorities (CAs) for issuing the certificates. This contrasts with web of trust models, like PGP, where anyone (not just special CAs) may sign and thus attest to the validity of others' key certificates. Version 3 of X.509 includes the flexibility to support other topologies like bridges and meshes. It can be used in a peer-to-peer, OpenPGP-like web of trust, but was rarely used that way as of 2004. The X.500 system has only ever been implemented by sovereign nations for state identity information sharing treaty fulfillment purposes, and the IETF's Public-Key Infrastructure (X.509), or PKIX, working group has adapted the standard to the more flexible organization of the Internet. In fact, the term X.509 certificate usually refers to the IETF's PKIX Certificate and CRL Profile of the X.509 v3 certificate standard, as specified in RFC 5280., commonly called PKIX for Public Key Infrastructure (X.509).
