Message Integrity Check (MIC, also named Michael) is a function designed to detect if someone has covertly altered data packets. The receiver and the transmitter each compute and compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped.
Message Integrity Code. A cryptographic “tag†attached to transmitted data to ensure the data's validity. The recipient of the data generates its own MIC and compares it to the one that was sent; if they're equal, the message is valid. Some MICs, such as those generated by gss_get_mic(), are visible to the application, while others, such as those generated by gss_wrap() or gss_init_sec_context(), are not.
Message Integrity Check. A technology that is employed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If it does not match, the data is assumed to have been tampered with and the packet is dropped. (See Packet, TKIP, WPA, WPA2). close

MIC (Message Integrity Check) prevents attacks on encrypted packets called bit-flip attacks. During a bit-flip attack, an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver accepts the retransmitted message as legitimate. The MIC, implemented on both the bridge and all associated client devices, adds a few bytes to each packet to make the packets tamper-proof.
Message Integrity Check. Also known as a "cryptographic checksum." For PICS, the importance of a MIC is that a rating service can compute the MIC of a piece of information when the label is created and that MIC can be put into the label itself. A client can retrieve the label and the information to which it is supposed to be attached, recompute the MIC and compare it to the one in the label. If they match, for all practical purposes, it is a proof that the label really belongs to the information that has been retrieved. The particular algorithm specified by PICS to compute the MIC is MD5.
Message integrity check. MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack, an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver accepts the retransmitted message as legitimate. The client adapter's driver must support MIC functionality, and MIC must be enabled on the access point.
Model-Integrated Computing ( MIC) addresses the problems of developing software integrated systems by providing rich, domain-specific modeling environments including model analysis and model-based program synthesis tools. This technology is used to create and evolve integrated, multiple-aspect models using concepts, relations, and model composition principles routinely used in the specific field, to facilitate systems/software engineering analysis of the models, and to automatically synthesize applications from the models. MIC has been used to develop many different technologies and solutions for industry and government. Please browse our updated web presense for more details of our technology, research, and projects.
message integrity check. Originally defined in Privacy Enhanced Mail (PEM) for authentication using MD2 or MD5. Message integrity calculation (Micalg) is used in secure MIME implementations.
Message Integrity Codes. A non-keyed message digests made without a secret key ; also known as Modification Detection Codes (MDC). Most public key digital signatures use non-keyed message digests.
