Method and system for handling security in an IP multimedia gateway

A system for communication, the system comprising:

• at least one of a processor and a circuit in an IP multimedia gateway (IMG), configured to:
• identify a client device communicatively coupled to said IMG, the client device having a security capability incompatible with a security capability of a service manager;
• and
• initiate a security conversion process between a first authentication method of said client device and a second authentication method of said service manager to enable said client device to receive a service from said service manager, wherein the first authentication method comprises an authentication via an identifier and the second authentication method comprises a digital certificate.

A method, comprising:

• identifying, by an IP multimedia gateway (IMG), a client device communicatively coupled to said IMG, the client device having a security capability incompatible with a security capability of a service manager, said client device not having an authorization to access content received from said service manager;
• and
• enabling, by said IMG, a security translation process between said client device and said service manager by performing access control conversion on said content to authorize said client device to access said content;
• and
• based on the security capability of the identified IMG, initiating said security translation process between a first cryptography method of said client device and a second cryptography method of said service manager to enable said client device to interpret said content received from said service manager, wherein said first cryptography method comprises a first authentication via a first cipher and said second cryptography method comprises a second authentication via a second cipher, wherein said first cipher is different from said second cipher.
