The international Common Criteria standard was developed to unify and supersede national IT security certification schemes from several different countries, including the US, Canada, Germany, the UK, France, Australia, and New Zealand. Common Criteria certified solutions are required by governments and enterprises around the world to protect their mission-critical infrastructures. It is a prerequisite that the individual components, which are combined to create a signing system that will produce qualified digital signatures, have relevant common criteria certifications under the European Union digital signature laws. Under Common Criteria, a product is evaluated to one of seven specific Evaluation Assurance Levels (EALs). Entrust nShield Connect, nShield Connect+, nShield Solo, nShield Solo+ and now nShield Solo XC and nShield Connect XC have all been certified to EAL4+, ensuring customers have the utmost confidence in Entrust's range of advanced cryptographic solutions.
