IT Security techniques — Entity authentication — Part 3: Mechanisms using digital signature techniques

IT Security techniques — Entity authentication — Part 3: Mechanisms using digital signature techniques

This document specifies entity authentication mechanisms using digital signatures based on asymmetric techniques. A digital signature is used to verify the identity of an entity. Ten mechanisms are specified in this document. The first five mechanisms do not involve an on-line trusted third party and the last five make use of on-line trusted third parties. In both of these two categories, two mechanisms achieve unilateral authentication and the remaining three achieve mutual authentication. Annex A defines the object identifiers assigned to the entity authentication mechanisms specified in this document.

Information security — Prime number generation

This document specifies methods for generating and testing prime numbers as required in cryptographic protocols and algorithms. Firstly, this document specifies methods for testing whether a given number is prime. The testing methods included in this document are divided into two groups: — probabilistic primality tests, which have a small error probability. All probabilistic tests described here can declare a composite to be a prime; — deterministic methods, which are guaranteed to give the right verdict. These methods use so-called primality certificates. Secondly, this document specifies methods to generate prime numbers. Again, both probabilistic and deterministic methods are presented. NOTE It is possible that readers with a background in algorithm theory have already had previous encounters with probabilistic and deterministic algorithms. The deterministic methods in this document internally still make use of random bits (to be generated via methods described in ISO/IEC 18031), and "deterministic" only refers to the fact that the output is correct with probability one. Annex A provides error probabilities that are utilized by the Miller-Rabin primality test. Annex B describes variants of the methods for generating primes so that particular cryptographic requirements can be met. Annex C defines primitives utilized by the prime generation and verification methods.

Information technology — Security techniques — Authentication context for biometrics

This document defines the structure and the data elements of Authentication Context for Biometrics (ACBio), which is used for checking the validity of the result of a biometric enrolment and verification process executed at a remote site. This document allows any ACBio instance to accompany any biometric processes related to enrolment and verification. The specification of ACBio is applicable not only to single modal biometric enrolment and verification but also to multimodal fusion. The real-time information of presentation attack detection is not provided in this document. Only the assurance information of presentation attack detection (PAD) mechanism can be contained in the BPU report. Biometric identification is out of the scope of this document. This document specifies the cryptographic syntax of an ACBio instance. The cryptographic syntax of an ACBio instance is defined in this document applying a data structure specified in Cryptographic Message Syntax (CMS) schema whose concrete values can be represented using a compact binary encoding. This document does not define protocols to be used between entities such as BPUs, claimant, and validator. Its concern is entirely with the content and encoding of the ACBio instances for the various processing activities.

IT Security techniques — Entity authentication — Part 2: Mechanisms using authenticated encryption

This document specifies entity authentication mechanisms using authenticated encryption algorithms. Four of the mechanisms provide entity authentication between two entities where no trusted third party is involved; two of these are mechanisms to unilaterally authenticate one entity to another, while the other two are mechanisms for mutual authentication of two entities. The remaining mechanisms require an on-line trusted third party for the establishment of a common secret key. They also realize mutual or unilateral entity authentication. Annex A defines Object Identifiers for the mechanisms specified in this document.

IT Security techniques — Hash-functions — Part 3: Dedicated hash-functions

This document specifies dedicated hash-functions, i.e. specially designed hash-functions. The hash-functions in this document are based on the iterative use of a round-function. Distinct round-functions are specified, giving rise to distinct dedicated hash-functions. The use of Dedicated Hash-Functions 1, 2 and 3 in new digital signature implementations is deprecated. NOTE As a result of their short hash-code length and/or cryptanalytic results, Dedicated Hash-Functions 1, 2 and 3 do not provide a sufficient level of collision resistance for future digital signature applications and they are therefore, only usable for legacy applications. However, for applications where collision resistance is not required, such as in hash-functions as specified in ISO/IEC 9797‑2, or in key derivation functions specified in ISO/IEC 11770‑6, their use is not deprecated. Numerical examples for dedicated hash-functions specified in this document are given in Annex B as additional information. For information purposes, SHA-3 extendable-output functions are specified in Annex C.

Information technology — Security techniques — Vulnerability disclosure

This document provides requirements and recommendations to vendors on the disclosure of vulnerabilities in products and services. Vulnerability disclosure enables users to perform technical vulnerability management as specified in ISO/IEC 27002:2013, 12.6.1[1]. Vulnerability disclosure helps users protect their systems and data, prioritize defensive investments, and better assess risk. The goal of vulnerability disclosure is to reduce the risk associated with exploiting vulnerabilities. Coordinated vulnerability disclosure is especially important when multiple vendors are affected. This document provides: — guidelines on receiving reports about potential vulnerabilities; — guidelines on disclosing vulnerability remediation information; — terms and definitions that are specific to vulnerability disclosure; — an overview of vulnerability disclosure concepts; — techniques and policy considerations for vulnerability disclosure; — examples of techniques, policies (Annex A), and communications (Annex B). Other related activities that take place between receiving and disclosing vulnerability reports are described in ISO/IEC 30111. This document is applicable to vendors who choose to practice vulnerability disclosure to reduce risk to users of vendors' products and services.

Guidance for developing security and privacy functional requirements based on ISO/IEC 15408

This document provides guidance for: — selecting and specifying security functional requirements (SFRs) from ISO/IEC 15408-2 to protect Personally Identifiable Information (PII); — the procedure to define both privacy and security functional requirements in a coordinated manner; and — developing privacy functional requirements as extended components based on the privacy principles defined in ISO/IEC 29100 through the paradigm described in ISO/IEC 15408-2. The intended audience for this document are: — developers who implement products or systems that deal with PII and want to undergo a security evaluation of those products using ISO/IEC 15408. They will get guidance how to select security functional requirements for the Security Target of their product or system that map to the privacy principles defined in ISO/IEC 29100; — authors of Protection Profiles that address the protection of PII; and — evaluators that use ISO/IEC 15408 and ISO/IEC 18045 for a security evaluation. This document is intended to be fully consistent with ISO/IEC 15408; however, in the event of any inconsistency between this document and ISO/IEC 15408, the latter, as a normative standard, takes precedence.

Information technology — Application security — Part 7: Assurance prediction framework

This document describes the minimum requirements when the required activities specified by an Application Security Control (ASC) are replaced with a Prediction Application Security Rationale (PASR). The ASC mapped to a PASR define the Expected Level of Trust for a subsequent application. In the context of an Expected Level of Trust, there is always an original application where the project team performed the activities of the indicated ASC to achieve an Actual Level of Trust. The use of Prediction Application Security Rationales (PASRs), defined by this document, is applicable to project teams which have a defined Application Normative Framework (ANF) and an original application with an Actual Level of Trust. Predictions relative to aggregation of multiple components or the history of the developer in relation to other applications is outside the scope of this document.
