| Authentic I-PDU | An Authentic I-PDU is an arbitrary AUTOSAR I-PDU the content of which is secured during network transmission by means of the Secured I-PDU. The secured content comprises the complete IPDU or a part of the I-PDU. | 969 | 7 | |
| Authentication | Authentication is a service related to identification. This function applies to both entities and information itself. Two parties entering into a communication should identify each other. Information delivered over a channel should be authenticated as to origin, date of origin, data content, time sent, etc. For these reasons, this aspect of cryptography is usually subdivided into two major classes: entity authentication and data origin authentication. Data origin authentication implicitly provides data integrity (for if a message is modified, the source has changed). | 969 | 7 | |
| Authentication Information | The Authentication Information consists of a Freshness Value (or a part thereof) and an Authenticator (or a part thereof). Authentication Information are the additional pieces of information that are added by SecOC to realize the Secured I-PDU. | 969 | 7 | |
| Authenticator | Authenticator is data that is used to provide message authentication. In general, the term Message Authentication Code (MAC) is used for symmetric approaches while the term Signature or Digital Signature refers to asymmetric approaches having different properties and constraints. | 969 | 7 | |
| AUTOSAR | AUTomotive Open System Architecture | 55 | 1 | |
| AUTOSAR Authoring Tool | An AUTOSAR Tool used to create and modify AUTOSAR XML Descriptions. Example: System Description Editor. | 535 | 70 | |
| AUTOSAR Definition | This is the definition of parameters which can have values. One could say that the parameter values are Instances of the definitions. But in the meta model hierarchy of AUTOSAR, definitions are also instances of the meta model and therefore considered as a description. Examples for AUTOSAR definitions are: EcucParameterDef, PostBuildVariantCriterion, SwSystemconst. | 535 | 70 | |
| AUTOSAR Meta-Model | This is an UML2.0 model that defines the language for describing AUTOSAR systems. The AUTOSAR meta-model is an UML representation of the AUTOSAR templates. UML2.0 class diagrams are used to describe the attributes and their interrelationships. Stereotypes, UML tags and OCL expressions (object constraint language) are used for defining specific semantics and constraints. | 535 | 70 | |
| AUTOSAR Meta-Model Tool | The AUTOSAR Meta-Model Tool is the tool that generates different views (class tables, list of constraints, diagrams, XML Schema etc.) on the AUTOSAR meta-model. | 535 | 70 | |
| AUTOSAR Model | This is a representation of an AUTOSAR product. The AUTOSAR model represents aspects suitable to the intended use according to the AUTOSAR methodology. Strictly speaking, this is an instance of the AUTOSAR meta-model. The information contained in the AUTOSAR model can be anything that is representable according to the AUTOSAR meta-model. | 535 | 70 | |
| AUTOSAR Partial Model | In AUTOSAR, the possible partitioning of models is marked in the meta-model by atpSplitable. One partial model is represented in an AUTOSAR XML description by one file. The partial model does not need to fulfill all semantic constraints applicable to an AUTOSAR model. | 535 | 70 | |
| AUTOSAR Processor Tool | An AUTOSAR Tool used to create non-AUTOSAR files by processing information from AUTOSAR XML files. Example: RTE Generator | 535 | 70 | |
| AUTOSAR Specification Element | An AUTOSAR Specification Element is a named element that is part of an AUTOSAR specification. Examples: requirement, constraint, specification item, class or attribute in the meta model, methodology, deliverable, methodology activity, model element, bsw module etc. | 535 | 70 | |
| AUTOSAR Template | The term "Template" is used in AUTOSAR to describe the format different kinds of descriptions. The term template comes from the idea, that AUTOSAR defines a kind of form which shall be filled out in order to describe a model. The filled form is then called the description. In fact the AUTOSAR templates are now defined as a meta-model. | 535 | 70 | |
| AUTOSAR Tool | This is a software tool which supports one or more tasks defined as AUTOSAR tasks in the methodology. Depending on the supported tasks, an AUTOSAR tool can act as an authoring tool, a converter tool, a processor tool or as a combination of those (see separate definitions). | 535 | 70 | |
| AUTOSAR Validation Tool | A specialized AUTOSAR Tool which is able to check an AUTOSAR model against the rules defined by a profile. | 535 | 70 | |
| AUTOSAR XML Description | In AUTOSAR this means "filled Template". In fact an AUTOSAR XML description is the XML representation of an AUTOSAR model. The AUTOSAR XML description can consist of several files. Each individual file represents an AUTOSAR partial model and shall validate successfully against the AUTOSAR XML schema. | 535 | 70 | |
| AUTOSAR XML Schema | This is a W3C XML schema that defines the language for exchanging AUTOSAR models. This Schema is derived from the AUTOSAR meta-model. The AUTOSAR XML Schema defines the AUTOSAR data exchange format. | 535 | 70 | |

| Distinction unilateral / bilateral authentication | In unilateral authentication, one side proves identity. The requesting side is not even authenticated to the extent of proving that it is allowed to request authentication. In bilateral authentication, the requester is also authenticated at least (see below) to prove the privilege of requesting. There is an efficient and more secure way to authenticate both endpoints, based on the bilateral authentication described above. Along with the authentication (in the second message) requested initially by the receiver (in the first message), the sender also requests an authentication. The receiver sends a third message providing the authentication requested by the sender. This is only three messages (in contrast to four with two unilateral messages). | 969 | 7 | |

| Entity authentication | Entity authentication is the process whereby one party is assured (through acquisition of corroborative evidence) of the identity of a second party involved in a protocol, and that the second has actually participated (i.e., is active at, or immediately prior to, the time the evidence is acquired). Note: Entity authentication means to prove presence and operational readiness of a communication endpoint. This is for example often done by proving access to a cryptographic key and knowledge of a secret. It is necessary to do this without disclosing either key or secret. Entity authentication can be used to prevent record-and-replay attacks. Freshness of messages only complicates them by the need to record a lifetime and corrupt either senders or receivers (real-time) clock. Entity authentication is triggered by the receiver, i.e. the one to be convinced, while the sender has to react by convincing. Record and replay attacks on entity authentication are usually prevented by allowing the receiver some control over the authentication process. In order to prevent the receiver from using this control for steering the sender to malicious purposes or from determining a key or a secret ("oracle attack"), the sender can add more randomness. If not only access to a key (implying membership to a privileged group) but also individuality is to be proven, the sender additionally adds and authenticates its unique identification. | 969 | 7 | |

| M0: AUTOSAR objects | This is the realization of an AUTOSAR system at work: For example a real ECUs executing a software image containing for instance the windshield wiper control software. | 1024 | 69 | |
| M1: AUTOSAR models | Models on this meta level are built by the AUTOSAR developers. They may define a software component called "windshield wiper" with a certain set of ports that is connected to another software component and so on. On this level all artifacts required to describe an AUTOSAR system are detailed, including re-usable types as well as specific instances of such types. The AUTOSAR software is loaded in to individual ECUs for individual vehicles. This loading means that the M1 Model is instantiated. Note that such an AUTOSAR model can be represented using various formats ranging from XML, to C even to PDF. | 1024 | 69 | |
| M2: AUTOSAR meta-model | On this meta level the vocabulary for AUTOSAR templates is defined. This vocabulary later can be used by developers of AUTOSAR based ECU systems. For example it is defined on M2 that in AUTOSAR we have an entity called "software component" which among others aggregate an entity called "port". This definition ensures that the developer of an AUTOSAR software component can describe his particular component and its ports. This description is called an AUTOSAR model and resides on M1. | 1024 | 69 | |
| M3: UML profile for AUTOSAR templates | The AUTOSAR templates on M2 are built according to the meta-model defined on M3. As discussed before this is UML tog | 1024 | 69 | |

| MAY | This word, or the adjective „OPTIONAL“, means that an item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because the vendor feels that it enhances the product while another vendor may omit the same item. An implementation, which does not include a particular option, MUST be prepared to interoperate with another implementation, which does include the option, though perhaps with reduced functionality. In the same vein an implementation, which does include a particular option, MUST be prepared to interoperate with another implementation, which does not include the option (except, of course, for the feature the option provides.) | 599 | 83 | |
