Trust establishment can be very delicate when it involves the exchange of sensitive information, such as affiliation to a secret society or to an intelligence agency. However, almost all of the applications are centralized and a trusted server is necessary. A private matchmaking protocol, she studied the matchmaking problem in the secret handshak IARIA is the owner of the publication and of editorial aspects.
Later, some authenticated key agreement [ 19 — 24 ] and anonymous key agreement [ 2526 ] protocols were developed and proposed.
This removes the main drawback found in previous protocols. Private handshaking is a useful tool for mutual authentication, demanded by many pervasive applications including RFID for privacy.
Facebook, LinkedIn, Myspace, Flicker, Plurk, and Twitter, for instance, are successful applications of social networking services. Beside privacy consideration, authentication [ 9 ] is also an important issue for matchmaking schemes, and authentication protocols, such as password-based authentication schemes [ 1011 ], are required.
Private set intersection PSI allows two parties to com-pute the intersection of their sets without revealing any information about items that are not in the intersection.
This approach reveals personal private information to anyone. However, prior to password authentication, key establishment and key agreement [ 12 — 16 ] are needed as well.
The application aims to find common friends of two users via their personal devices, such as cell phones or PDA, directly, wirelessly and privately. We present simple and efficient protocols for both the single group and multiple group membership case.
Furthermore, it authenticates the exchanged information and avoids forging problems. Only necessary and minimal information about the private attributes of the participating users is exchanged to limit the risk of privacy exposure. This approach allows the server to track users. Our implementations are efficient enough to support such usually resource constrained scenarios.
The schemes proposed in the literature are either limited versions of secret handshake supporting revocation, or they support more complete versions of secret handshake with no possibility of introducing revocation. Private Matching Freedman et al.
However in their schemes [ 731 ], trusted third parties, identity signer and personal interest signer, are required to issue identity certificates and create interests signatures, and social networking friendships cannot be proved directly. The proposed scheme is demonstrated to be secure, effective, and efficient.
The complex security solution is split into smaller parts, which are described in an abstract way.

Keywords-security patterns; secret handshake; cryptographic protocols; mutual authentication; I. The structured description together with motivating scenarios makes the security so-lution better understandable for non-security experts and helps to disseminate the security knowledge to application developers.
Some common problems are the authenticity of social contacts, the privacy of online communication, and the lack of physical interaction. Revocation of credentials in Secret Handshakes is a difficult challenge, as it mixes the conflicting requirements of tracing revoked users and of the untraceabilit The implementation of the proposed algorithms on Android system mobile devices allows users to securely find their target via mobile phones.
Abstract—A security pattern describes a particular recurring security problem that arises in specific contexts and presents a well-proven generic solution for it. This work merges characteristics of Secret Handshake with features peculiar to Secure Matchmaking.LEVEL Connections is a modern approach to traditional matchmaking to make dating more rewarding and effortless.

For example. Private matchmaking is interesting because it has conflicting requirements for anonymity and authentication.
A private matchmaking protocol allows two or more mutually suspicious parties with matching credentials to locate and authenticate each other without revealing their credentials or identities to anyone including the matchmaker. A private matchmaking protocol allows two or more mutually suspicious parties with matching credentials to locate and authenticate each other without revealing their credentials or identities to anyone including the matchmaker.
