The objective of this is to support a structure for issuing public keys, basing itself on the principle of the trusted third party, offering a mediation of credibility and trust in transactions between parties that use digital certificates.

Since NOSi is in the process of becoming a second level certification entity, it can issue certificates to people and entities. It will define a set of techniques, practices and procedures to be adopted by entities in order to establish a digital certification system based on public keys. All certificates issued by NOSi's PKI shall be used by the various holders, systems, applications, mechanisms and protocols, in order to guarantee the following services: Access Control; Confidentiality and Integrity; Authentication; Non-Repudiation.

Such services will be obtained using cipher algorithms, the use of public key cryptography, managed by certified cryptographic equipment.
